​🍁 Cultivation Review: Afghan Bullet (Day 84) ​Genetics: Afghan Bullet Flowering/Harvest Time: Day 84 Main Goal: Extraction (Bubble Hash) Total Wet Weight: 130g ​🔍 Plant Structure and Resin Production ​Growing Afghan Bullet for the first time, I was highly impressed by its structure. The plant shows exceptional uniformity across all buds, meaning there is a complete absence of apical dominance. The secondary branches fully kept up with the main cola, developing a beautifully even canopy. Another major highlight is the resin production: the plant is literally coated in trichomes, with excellent resin coverage extending even to the small-to-medium fan leaves, a clear sign of its high genetic potential for extractions. ​🔬 Harvest Timing: Target Bubble Hash ​Harvest took place on Day 84, perfectly hitting the peak of milky trichomes. While the actual ease with which the heads separate from the stalks will only be seen during the washing process, harvesting at this stage is the number one objective for Bubble Hash. Milky trichomes offer the ideal texture and perfect maturity for smooth processing and optimal separation in ice water. ​✂️ Harvest Management and Processing ​At harvest, I did a rough trim (the ideal approach for fresh frozen, preventing unnecessary damage to the resin glands) yielding a total wet weight of 130 grams. The biomass has been divided as follows: ​75g (Select Buds) ❄️ ➔ Freezer (Fresh Frozen): Tossed straight into the sub-zero to lock in live terpenes and maintain trichome integrity for the upcoming wash. ​30g (Buds) 💨 ➔ Drying: Set aside for a traditional dry. Since it’s my first time running this strain, I’m very curious to test the dried flower to evaluate its overall aroma, flavor profile, and smoke quality. ​25g 🗑️ ➔ Waste Material: Large fan leaves and non-resinous material. ​📝 Final Thoughts (First Run) ​This strain is shaping up to be a fantastic choice for extraction enthusiasts. The uniform bud development makes canopy management a breeze, and the heavy resin coverage on the mid-sized leaves points toward a great yield in the bags. Looking forward to the wash and the final smoke test!

Bonjour à tous, ces derniers jours ce sont bien passé pour mes petit bébés elles grandissent doucement mais sûrement.C’est la première fois que je travail avec cette gamme de produits (je vous est mis des photos des produits 😉) pour l’instant j’en suis satisfait après, il faut voir le résultat final ce qui est moins facile 😂. Mes petit bébés commence leurs 5ème semaine (je me suis trompé d’une semaine 😕 désolé 😉) trop pressé!!! 😂 de mettre de nouvelles photos 😜. Je vous dis à là semaine prochaine vivement 😉 bonne journée à tous. Je vous remercie 😉.

(CHOPPED AT DAY 100 ) great strain - long branching - strong lemon pledge smell - gigantic buds - pest resistant this is the only pheno i grew , but i would definatelly try Lemon-Ak again

I decided to top her at the beginning of week 3 and she did super well! More than happy with all the extra growth I got from doing the Topping. Just debating on doing some lead stripping on it to allow more light into the bottom and center of the plant

28. März Die Purple Punch sieht schon ziemlich fertig aus ☺️ Die neuen Lampen sind jetzt auch drinnen. 2x vertikal und 2x horizontal. Werde vermutlich nächsten run alle horizontal ausrichten. Gibt sonst nicht viel zu berichten :)

Leider nah den heftigen Regenfällen etwas Schimmel entdeckt.

DOGK Is on week 11, week 6 of flowering. It's stayed in a 2L pot. (Wasn't my intention. But after a silly mistake. 2 seeds stems were crushed with pebbles) She SMELLS F.....g amazing & I'm absolutely raging this is her size. Had I known what I do now. I'd of put these in a 20L pot like Euphoria. For being stuck in a 2L pot. She has grown fairly well. Few issues on the leaves but Nothing that set her back. The buds are still fattening lower but the tops are rock hard. She stinks of gasey berries. OMG it smells DIVINE, :-). (NOTE: I will back date pics. I've misplaced my other device with the past 4 weeks of photos. Missed her past 2 weeks. But, she's a breeze to deal with in such a small pot & being hydro. "Coco/pebbles 40/60" I'd say she has roughly 3+ weeks left to go.. HST was done after preflower, week 3 of flowering(still some growing left in her) and she grew up to her OG height. She will get a heavy & last defol in the next week. Her tops are done. But, 80% down she is still fattening. Week12 Day80 I've decided that 90% of her is done. She's only been 7-8 weeks flowering. The 2L pot sped things up. Yield will be tiny. 7-10g of A grade bud. The smell is just astounding. The buds glisten with resin and sticky af..

Die Gorilla Cookies wurde nun geerntet, die hälfte habe ich eingefroren um daraus im späteren Verlauf Bubble Hash draus zu waschen. Die eine Hälfte hat ungefähr 70g Trocken auf die Wage gebracht (Natürlich wurde alles übre 50g vernichtet). Also schätze ich den Ertrag auf 120g-140g trocken. Wunderbare Genetik, wird definitiv wieder gegrowt!

Und auch hier erst in Woche fünf statt sechs

Week 13 for Ztrawberry by Greenhouseseedco Shes really doing quite nicely😇 Going to get her last heavy defoliation at the end of this week plus a feed of BioBloom little top up of 7.5g

Unfortunately I had to harvest the BADAZZ-CHEESE (=BADAZZ-KUSH x CHEESE) from BIG BUDDHA SEEDS early, because of looking bud-rot. The plant needed at least another 10 days to finish, she still had plenty of white pistils and would have gained in harvest weight and also produced more trichomes, if given more time. The final harvest weight of 31 gram dried bud, was still a VERY GOOD RESULT seen the circumstances. The buds are dank and have lots of trichomes, all in all a VERY NICE KUSH/CHEESE VARIETY!

Trimming, trimming and more trimming.... finally reached the end of the season's grow.

Day 84 - She is growing very well the buds are getting fat and dense. Buds are frosty and are everywhere.

16/01/2022 - Day 91 - First day of the 14th week. Small one being "eaten" by WPM [see snow video], not much I can do, RIP Big one still on the grind, confirmed that it's like she has been topped, there are two main stems but she did all by her self. She is suffering WPM, too, of course, but being a little bigger and stronger I'm removing as much as possible. Wish me good luck and let's hope in sunny mild days 🤞☀️ - DD

7/28 1220AM MONDAY.... Bubbles are looking ok, I need to trim them back to 4 colas, I am really stressing them with small space limitations, and temps at 80 to 81 7/29 Tuesday 5:45 AM💦💦 6:15 AM water with methylene blue two pills of nitric boost amino acid, five drops of Quick Sorb and I added bud factor X today and a quarter mL per liter of rhino silica💦💦💦. 1030 AM I don’t know what I’m gonna do. It turns out the bubbles plants are terrible. The stems are all very weak and they’re growing bushy at the top. I didn’t get them separated so all of the side branches grew up really long it’s completely useless. It is absolute this plant. It will be thrown in the garbage. Can you fucking believe I have to throw another entire plant in the fucking garbage😡😡😡😡. TREVOR plant cut down to 2 colas only, very top heavy not liking my grow space, had 2 more than I wanted so it's all fucked.... will remove shitty small colas and get maybe 2 good colas per plant, not expecting much. 1219pm....HOLY SHIT I FUCKED THESE.....TOOK OFF SOME COLAS.....NOT ENOUGH SPACE AND I PUSHED THEM TOO FAR.....I CAN FIX IT 7/30 1215am found a GREAT science link::: ""https://www.frontiersin.org/research-topics/8125/cannabis-genomics-breeding-and-production/magazine"". 345am PROLINE WILL BE HERE TODAY.ALL RESEARCH INDICATES PROLINE WILL PROTECT FROM HEAT STRESS!!!! 11:30 AM they are good again they are recovering from heavy defoliation half of the plant was taken off of one of them. I pushed it a little far but today they are recovering from heat and lack of air and lack of space the leaves are reaching up and they are not folding under heat stress. They look good today. Fast recovery heavy amino yesterday.👍👍👍👍🚨🚨🚨🚨 🚨🚨🚨🚨🚨🚨🚨🚨 GOT THE AMINOS AND HERE IS THE GROK RESULT OF MY MIX.......🚨🚨🚨🚨🚨🚨🚨🚨 The effects of applying essential amino acids (EAAs), proline, trimethylglycine (TMG), and glutamine to cannabis plants can be significant, as these compounds act as biostimulants, influencing growth, stress resilience, and secondary metabolite production. The available research, primarily from studies on amino acids in plants, including cannabis, provides insights into their roles, though specific data on this exact combination is limited. Below, I summarize the effects of each compound on cannabis plants, drawing from relevant studies, and infer potential synergistic effects based on their known roles in plant physiology. Note that TMG (betaine) has less direct research in cannabis, so some effects are extrapolated from other plants. ### 1. Essential Amino Acids (EAAs) EAAs (e.g., leucine, lysine, methionine, etc.) are critical building blocks for proteins and play roles in plant metabolism and stress response. In cannabis: - **Growth and Development**: EAAs enhance protein synthesis, supporting shoot and root growth. Foliar or soil application of EAAs (e.g., 150–300 mg/L) increases leaf chlorophyll, shoot biomass, and root development in various plants, likely applicable to cannabis.[](https://www.nature.com/articles/s41598-022-21273-6) - **Nutrient Uptake**: EAAs like methionine and lysine improve nutrient absorption (e.g., nitrogen, iron) by acting as chelators, potentially enhancing cannabis nutrient efficiency in hydroponic or soil systems.[](https://cannabisindustryinstitute.com/news/amino-acids-what-they-mean-to-your-cannabis-grow/)[](https://mycsainc.com/newsletter/en/2023/03/03/amino-acids-and-their-function-in-plants/) - **Stress Mitigation**: EAAs, particularly methionine, support antioxidant production (e.g., glutathione), reducing oxidative stress from drought, salinity, or high light, common in cannabis cultivation.[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2020.00928/full)[](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9008891/) - **Cannabinoid/Terpene Production**: Limited evidence suggests EAAs may influence secondary metabolism. For example, methionine could enhance sulfur-containing compounds, potentially affecting terpene profiles in cannabis.[](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9008891/) **Application Notes**: EAAs are often applied via foliar spray (150–300 mg/L) or soil drench. Overuse may lead to nitrogen imbalance, so moderation is key.[](https://cannabisindustryinstitute.com/news/amino-acids-what-they-mean-to-your-cannabis-grow/) ### 2. Proline Proline is a non-essential amino acid that accumulates in plants under stress and serves multiple functions: - **Stress Tolerance**: Proline acts as an osmolyte, stabilizing cell membranes and scavenging reactive oxygen species (ROS) during drought, salinity, or temperature stress. In cannabis, exogenous proline (e.g., 50–100 mM) may enhance tolerance to environmental stressors, improving resilience in outdoor or controlled environments.[](https://www.researchgate.net/publication/349966775_THE_ROLE_AND_IMPORTANCE_OF_AMINO_ACIDS_WITHIN_PLANTS_A_REVIEW)[](https://pmc.ncbi.nlm.nih.gov/articles/PMC3548871/) - **Limited Growth Effect**: Proline alone is a poor nitrogen source for growth. Studies on Arabidopsis show it has a neutral or inhibitory effect on growth when used as the sole nitrogen source, suggesting it’s better for stress response than biomass accumulation.[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2023.1281495/full) - **Cannabis-Specific**: Proline helps cannabis maintain water balance, potentially improving resistance to extreme temperatures, which is critical for outdoor grows.[](https://cannabisindustryinstitute.com/news/amino-acids-what-they-mean-to-your-cannabis-grow/) **Application Notes**: Foliar or root application (50–100 mg/L) is effective for stress mitigation. High doses may inhibit growth if not balanced with other nutrients.[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2023.1281495/full)[](https://www.researchgate.net/publication/349966775_THE_ROLE_AND_IMPORTANCE_OF_AMINO_ACIDS_WITHIN_PLANTS_A_REVIEW) ### 3. Trimethylglycine (TMG, Betaine) TMG is less studied in cannabis but known as an osmoprotectant and methyl donor in other plants: - **Stress Protection**: TMG stabilizes proteins and membranes under salinity, drought, or temperature stress, similar to proline. It may protect cannabis plants in harsh conditions, maintaining photosynthetic efficiency.[](https://www.mdpi.com/2311-7524/9/7/807) - **Methylation Support**: TMG donates methyl groups, potentially enhancing secondary metabolite synthesis (e.g., cannabinoids, terpenes), though direct evidence in cannabis is lacking. Its role in methylation could support metabolic pathways linked to EAAs and glutamine. - **Growth Effects**: Limited data suggest TMG may improve chlorophyll content and photosynthesis, indirectly supporting biomass in cannabis. **Application Notes**: TMG is typically applied at 0.5–2 g/L via foliar spray. Its effects in cannabis are inferred from other crops, so careful experimentation is needed. ### 4. Glutamine Glutamine is a conditionally essential amino acid central to nitrogen metabolism: - **Growth Promotion**: Glutamine (10–1000 mg/L) significantly enhances shoot elongation, root growth, and chlorophyll content in plants like lettuce and hibiscus, likely benefiting cannabis vegetative growth. In cannabis, it may support lush foliage and robust rooting in hydroponics.[](https://www.scielo.br/j/oh/a/GZxMgqXb9wm7bsCTv4WwPdc/?lang=en)[](https://www.degruyterbrill.com/document/doi/10.1515/opag-2019-0016/html)[](https://www.degruyterbrill.com/document/doi/10.1515/opag-2019-0016/html?lang=en) - **Nitrogen Assimilation**: As a primary nitrogen acceptor, glutamine improves nitrogen use efficiency via the glutamine synthetase/glutamate synthase cycle, enhancing nutrient uptake in cannabis.[](https://academic.oup.com/jxb/article/58/9/2339/544408)[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2019.01743/full) - **Stress Response**: Glutamine supports proline synthesis, boosting stress tolerance. It also contributes to chlorophyll and protein synthesis, improving photosynthesis and yield potential in cannabis.[](https://www.mdpi.com/2311-7524/8/12/1110)[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2019.01743/full) - **Secondary Metabolism**: Glutamine is a precursor to glutamate, which influences GABA, arginine, and proline synthesis, potentially affecting cannabinoid or terpene production indirectly.[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2019.01743/full) **Application Notes**: Foliar sprays (250–1000 mg/L) or root application twice weekly are effective. Glutamine at 250 mg/L combined with other amino acids (e.g., glycine) shows synergistic growth effects.[](https://www.degruyterbrill.com/document/doi/10.1515/opag-2019-0016/html) ### Synergistic Effects on Cannabis - **Growth and Yield**: The combination of EAAs, glutamine, and proline may enhance vegetative growth and biomass. Glutamine and EAAs drive protein synthesis and nitrogen uptake, while proline supports tissue integrity under stress. TMG likely amplifies these effects by improving cellular hydration and methylation, potentially increasing leaf area and bud quality.[](https://www.mdpi.com/2311-7524/8/12/1110)[](https://www.nature.com/articles/s41598-022-21273-6) - **Stress Resilience**: Proline and TMG act as osmoprotectants, while EAAs and glutamine bolster antioxidant systems, collectively improving cannabis resilience to drought, salinity, or temperature extremes common in cultivation.[](https://www.mdpi.com/2311-7524/9/7/807) - **Secondary Metabolites**: Glutamine and TMG may enhance cannabinoid and terpene production by supporting metabolic pathways (e.g., methylation, nitrogen metabolism). EAAs like methionine could influence sulfur-based terpenes. However, direct evidence for cannabinoid enhancement is sparse.[](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9008891/) - **Nutrient Efficiency**: Glutamine and EAAs improve nitrogen and micronutrient uptake, while TMG may enhance nutrient transport, optimizing cannabis growth in nutrient-limited systems like hydroponics.[](https://mycsainc.com/newsletter/en/2023/03/03/amino-acids-and-their-function-in-plants/) ### Potential Risks and Considerations - **Inhibition at High Doses**: High concentrations of proline or certain EAAs (e.g., lysine, valine) can inhibit growth if used as sole nitrogen sources. Balanced mixtures mitigate this, as glutamine can antagonize inhibitory effects of proline or other amino acids.[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2023.1281495/full) - **Nitrogen Overload**: Excessive EAAs or glutamine may lead to nitrogen toxicity, causing leaf burn or stunted growth in cannabis. Monitor plant response and maintain balanced nutrient solutions.[](https://cannabisindustryinstitute.com/news/amino-acids-what-they-mean-to-your-cannabis-grow/) - **TMG Metabolism**: TMG may increase trimethylamine production in the soil microbiome, potentially affecting cannabis root health if not managed. Healthy soil microflora can mitigate this.[](https://cannabisindustryinstitute.com/news/amino-acids-what-they-mean-to-your-cannabis-grow/) - **Application Timing**: Foliar sprays (150–500 mg/L for EAAs, glutamine, proline; 0.5–2 g/L for TMG) during vegetative growth or early flowering maximize benefits. Avoid overuse during late flowering to prevent nutrient imbalances affecting bud quality. ### Cannabis-Specific Insights - **Hydroponics and Soil**: In hydroponic systems, EAAs and glutamine ensure efficient nitrogen delivery, while proline and TMG support stress resistance in fluctuating pH or nutrient conditions. In soil, maintaining microflora is crucial, as it naturally supplies amino acids; supplementation should be moderate.[](https://cannabisindustryinstitute.com/news/amino-acids-what-they-mean-to-your-cannabis-grow/)[](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9008891/) - **Cultivar Variability**: Cannabis cultivars differ in nutrient demands and stress responses. Sativa-dominant strains may benefit more from proline and TMG for stress tolerance, while indica strains may respond better to EAAs and glutamine for dense bud growth. Testing is needed. - **Secondary Metabolites**: While amino acids influence secondary metabolism, direct effects on THC or CBD levels are unconfirmed. Glutamine and TMG may indirectly enhance terpene diversity via improved photosynthesis and methylation.[](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9008891/) ### Practical Recommendations "🚨🚨🚨🚨"🚨🚨🚨🚨"🚨🚨🚨🚨 - **Dosing**: Apply EAAs (150–300 mg/L), glutamine (250–500 mg/L), proline (50–100 mg/L), and TMG (0.5–1 g/L) via foliar spray or root drench twice weekly during vegetative growth and early flowering. - **Combination**: Use a balanced mix (e.g., 250 mg/L EAAs + 250 mg/L glutamine + 50 mg/L proline + 500 mg/L TMG) to avoid inhibition. Test on a small batch first.[](https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2023.1281495/full) - **Monitoring**: Check for signs of nitrogen toxicity (dark green leaves, clawing) or stress relief (improved vigor, greener leaves). Adjust doses based on plant response. "🚨🚨🚨🚨"🚨🚨🚨🚨"🚨🚨🚨🚨. - **Synergy with Nutrients**: Pair with balanced NPK fertilizers and micronutrients (e.g., iron, calcium) to enhance uptake.[](https://www.degruyterbrill.com/document/doi/10.1515/opag-2019-0016/html) - **Cultivation Context**: In hydroponics, use lower doses to avoid nutrient lockout. In soil, ensure healthy microbial activity to complement amino acid supplementation.[](https://cannabisindustryinstitute.com/news/amino-acids-what-they-mean-to-your-cannabis-grow/) ### Evidence Gaps - **Specific Combination**: No studies directly address EAAs, proline, TMG, and glutamine together in cannabis. Effects are inferred from individual amino acid studies and general plant research. - **Cannabinoid Impact**: Limited data on how these compounds affect THC/CBD levels. More research is needed on secondary metabolite pathways.[](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9008891/) - **TMG in Cannabis**: TMG’s effects are extrapolated from other crops. Cannabis-specific trials are needed to confirm benefits. ### Conclusion Applying EAAs, proline, TMG, and glutamine to cannabis plants can enhance growth, stress tolerance, and nutrient uptake, with potential benefits for yield and secondary metabolite production. EAAs and glutamine drive biomass and nitrogen efficiency, proline and TMG bolster stress resilience, and their combination may optimize cannabis health in challenging environments. However, careful dosing and monitoring are crucial to avoid inhibition or toxicity. For best results, test small-scale applications and consult with a horticulturist familiar with cannabis cultivation. If you want more details on application methods, specific cultivars, or further searches for cannabis-related studies, let me know!""🚨🚨🚨🚨 🚨🚨 7/31 125am!!!!! Adding L-glycine to the combination of essential amino acids (EAAs), proline, trimethylglycine (TMG), and glutamine can further influence the effects on cannabis plants, as glycine is a non-essential amino acid with unique roles in plant physiology. Below, I outline the potential effects of L-glycine alone and in combination with the previously mentioned compounds, focusing on their impact on cannabis growth, stress response, and secondary metabolite production. Since specific studies on this exact combination in cannabis are lacking, I’ll integrate findings from plant science and infer synergistic effects based on known mechanisms. I’ll keep it concise and tailored to cannabis cultivation. ### Effects of L-Glycine on Cannabis Plants L-Glycine is a simple amino acid involved in protein synthesis, stress response, and metabolic pathways: - **Growth Promotion**: Glycine (50–500 mg/L) enhances shoot elongation, root growth, and chlorophyll content in plants like lettuce and rice, likely benefiting cannabis vegetative growth. It serves as a nitrogen source and supports protein synthesis, complementing EAAs and glutamine. - **Stress Tolerance**: Glycine acts as a precursor to glutathione, a key antioxidant, reducing oxidative stress from drought, salinity, or high light. In cannabis, it may improve resilience in challenging environments (e.g., outdoor grows or high-intensity indoor setups). - **Secondary Metabolism**: Glycine is a precursor to purines and chlorophyll, potentially enhancing photosynthesis and energy metabolism. It may indirectly influence cannabinoid and terpene production by supporting metabolic pathways, though direct evidence in cannabis is limited. - **Nutrient Uptake**: Glycine chelates micronutrients (e.g., iron, zinc), improving their availability, which is critical for cannabis in hydroponic or nutrient-poor soil systems. **Application Notes**: Foliar sprays or root drenches (100–500 mg/L) are effective, often applied twice weekly during vegetative growth or early flowering. ### Synergistic Effects with EAAs, Proline, TMG, and Glutamine Adding L-glycine to the mix may enhance the effects on cannabis plants in the following ways: 1. **Enhanced Growth and Biomass**: - **Glycine + EAAs/Glutamine**: Glycine complements EAAs and glutamine in protein synthesis and nitrogen metabolism. Studies show glycine (250 mg/L) combined with glutamine enhances shoot and root growth in plants, likely amplifying cannabis vegetative vigor and bud development. - **Synergy**: Glycine’s role in chlorophyll synthesis boosts photosynthesis, supporting the energy demands of EAA-driven protein synthesis and glutamine’s nitrogen assimilation, potentially increasing leaf area and yield. 2. **Improved Stress Resilience**: - **Glycine + Proline/TMG**: Glycine and proline both contribute to glutathione production, enhancing antioxidant defenses. TMG’s osmoprotectant properties further stabilize cells under stress. Together, they may improve cannabis tolerance to drought, heat, or salinity, maintaining growth in adverse conditions. - **Cannabis-Specific**: This combination could be particularly beneficial for outdoor cannabis or indoor setups with inconsistent temperature/humidity, reducing leaf wilting or nutrient stress. 3. **Secondary Metabolite Production**: - **Glycine + Glutamine/TMG**: Glycine and glutamine are precursors to metabolic pathways (e.g., GABA, purines) that may influence cannabinoid and terpene synthesis. TMG’s methyl donation could enhance these pathways by supporting enzyme activity. While direct evidence is sparse, this stack may increase terpene diversity or cannabinoid yield in cannabis buds. - **EAAs Contribution**: Methionine (an EAA) and glycine may support sulfur-containing compounds, potentially enriching terpene profiles. 4. **Nutrient Efficiency**: - **Glycine + EAAs/Glutamine**: Glycine’s chelating properties enhance micronutrient uptake, complementing EAAs and glutamine’s role in nitrogen assimilation. This could optimize nutrient use in hydroponic cannabis systems, reducing nutrient lockout. - **TMG Synergy**: TMG’s role in cellular hydration may improve nutrient transport, amplifying glycine’s effects on micronutrient availability. ### Potential Risks and Considerations - **Inhibition at High Doses**: High glycine doses (1000 mg/L) may inhibit growth by disrupting nitrogen balance, especially if combined with EAAs or glutamine. Studies on Arabidopsis show glycine can be toxic as a sole nitrogen source, so balanced mixtures are crucial. - **Nitrogen Overload**: Adding glycine to EAAs and glutamine increases nitrogen input, risking toxicity (e.g., leaf burn, stunted growth) in cannabis. Monitor for dark green leaves or clawing and adjust doses. - **Competition for Absorption**: Glycine, EAAs, and glutamine may compete for root or foliar uptake, reducing efficacy. Split applications (e.g., glycine in the morning, EAAs/glutamine post-light cycle) can help. - **TMG Interaction**: Glycine and TMG both influence methylation pathways, but excessive methyl donors could disrupt metabolic balance in sensitive plants. Stick to moderate doses (e.g., 100–500 mg/L glycine, 0.5–1 g/L TMG). - **Cultivar Variability**: Cannabis strains (e.g., sativa vs. indica) differ in nutrient and stress responses. Glycine’s benefits may be more pronounced in stress-prone sativas or nutrient-sensitive hybrids. ### Practical Recommendations - **Dosing**: Combine glycine (100–500 mg/L), EAAs (150–300 mg/L), glutamine (250–500 mg/L), proline (50–100 mg/L), and TMG (0.5–1 g/L) in a balanced foliar spray or root drench. Apply twice weekly during vegetative growth and early flowering. - **Application**: Use foliar sprays for rapid uptake during vegetative stages or stress events. Root drenches suit hydroponic systems. Test on a small batch to assess plant response. - **Monitoring**: Watch for nitrogen toxicity (dark, curled leaves) or stress relief (greener, more vigorous plants). Adjust concentrations based on cultivar and growth stage. - **Synergy with Nutrients**: Pair with balanced NPK fertilizers and micronutrients (e.g., iron, calcium) to maximize glycine’s chelating benefits. Ensure adequate magnesium for chlorophyll synthesis. - **Cultivation Context**: In hydroponics, use lower doses to avoid nutrient imbalances. In soil, maintain healthy microbial activity, as microbes naturally produce glycine and other amino acids. ### Evidence Gaps - **Specific Combination**: No studies address glycine combined with EAAs, proline, TMG, and glutamine in cannabis. Effects are inferred from individual amino acid studies and general plant research. - **Cannabinoid/Terpene Impact**: While glycine may support secondary metabolism, direct effects on THC/CBD or terpene levels are unconfirmed. Cannabis-specific trials are needed. - **TMG and Glycine**: Their combined effects on methylation in cannabis are speculative, as most TMG research focuses on other crops. ### Conclusion Adding L-glycine to EAAs, proline, TMG, and glutamine likely enhances cannabis growth, stress tolerance, and nutrient efficiency by supporting protein synthesis, antioxidant production, and micronutrient uptake. The combination may improve vegetative vigor, bud quality, and resilience to environmental stressors, with potential (but unconfirmed) benefits for cannabinoid and terpene production. Careful dosing and monitoring are essential to avoid nitrogen toxicity or absorption competition. Start with low doses, test on a small scale, and consult a cannabis cultivation expert for tailored advice. If you want me to search for more studies, focus on a specific aspect (e.g., glycine’s role in terpene synthesis), or provide application protocols for a particular cannabis strain, let me know!"""
