Plants with more direct UV showed much more purple across all 3 plants. The data shows that the number of terpenes in dried Cannabis flowers increases with a “No Red” light treatment for the final three days of production. Based upon these findings, we feel confident in recommending a spectrum control program that eliminates red light output from fixtures for the final 72 hours of the Cannabis flowering cycle. Terpenes are aromatic compounds that give cannabis some of its most distinct aromas from citrus and berry, to more earthy tones. Many species of plants produce and emit terpenes in a diurnal, or daily cycle that is regulated by a complex web of signaling. There are also many plants that emit terpenes at night to attract nocturnal pollinators (Marinho et al., 2014346). Regardless of when the terpenes are produced or emitted, these processes are often dependent upon cues derived from natural light/dark cycles via a native circadian clock (Dudareva et al., 2004). Several light-sensitive pigments are involved in these processes of production and emission, and the different photoreceptors are dependent upon different wavelengths of light to be activated or deactivated. Emission of terpenes is a process that is entirely dependent upon phytochromes and red/far-red light cues in most plant species (Flores and Doskey, 2015). For example, repeated light/dark phytochrome signaling is necessary for the emission of terpenes in tobacco plants (Roeder et al., 2007). Based on previous findings, we hypothesized that a lack of red light and phytochrome-mediated light/dark signaling on the part of the plant is responsible for an increase in terpene content in cannabis. The plant continues to synthesize terpenes, but a lack of red light to trigger the Pr-Pfr shift results in a lack of terpene emission by the plant, thus causing the terpenes to accumulate in the maturing flowers.

Plant Mol Biol 65: 107-12 Abstract Sound waves technology has been applied to different plants. It has been found that sound waves were at different frequencies, sound pressure levels (SPLs), exposure periods, and distances from the source of sound influence plant growth. Experiments have been conducted in the open field and under greenhouse growing conditions with different levels of audible sound frequencies and sound pressure levels. Sound waves at 1 kHz and 100 dB for 1 h within a distance of 0.20 m could significantly promote the division and cell wall fluidity of callus cells and also significantly enhance the activity of protective enzymes and endogenous hormones. Sound waves stimulation could increase the plant plasma-membrane H+-ATPase activity, the contents of soluble sugar, soluble protein, and amylase activity of callus. Moreover, sound waves could increase the content of RNA and the level of transcription. Stress-induced genes could switch on under sound stimulation. Sound waves at 0.1–1 kHz and SPL of (70±5) dB for 3 h from plant acoustic frequency technology (PAFT) generator within a distance ranged from 30 to 60 m every other day significantly increased the yield of sweet pepper, cucumber and tomato by 30.05, 37.1 and 13.2%, respectively. Furthermore, the yield of lettuce, spinach, cotton, rice, and wheat were increased by 19.6, 22.7, 11.4, 5.7, and 17.0%, respectively. Sound waves may also strengthen plant immune systems. It has been proved that spider mite, aphids, gray mold, late blight and virus disease of tomatoes in the greenhouses decreased by 6.0, 8.0, 9.0, 11.0, and 8.0%, respectively, and the sheath blight of rice was reduced by 50%. This paper provides an overview of literature for the effects of sound waves on various growth parameters of plant at different growth stages. https://doi.org/10.1016/S2095-3119(13)60492-X

2-24 1 gallon plain water, 6.4. She may get mad, I didn't add cal/mag. 2-25 Slightly adjusted LST, just to give a little more space. She sure is purdy 😻 Removed few leaves for light. Guy didnt mind. He had a all you can eat buffet 😂😂 3-1 1 gallon 5 ml cal/mag, 1 ml drops, 20 ml EM 1, 1.5 ml Amplify. Bubbling for 4 hrs. PH 6.4 ish Ohhh boy, she sure is gonna be happy today. 😁😁 See you next week!

I'm a little late on the update, super busy. Everything is still looking good. I took 2 of the smallest clones down as a sample. Other than slightly harsh due to quick dry is was good for early. Definitely looking forward to full maturity!!! I figure they have another week and they're done. I can smell the wine and the trim already 😁❤️😁 Happy growing everyone ✌️🍀✌️

10 dernier jours.

All is good so far, the seeds of all the different strains have been quite vigorous. Lost my first sour diesel due to my impatience, but the second time around was a charm .

There we are:)

Now that I see how these girls turned out it was probably a blessing I had some herms to cut out because there would’ve been no room. Especially in the pc/ssh tent because Pcrit and Sundae Driver were looking to be the biggest plants before I found balls and cut them down. The humidity has been surprisingly high but we’ve had warmer, wet weather for this time of year. I’m not sure I would’ve been able to keep it down with a tent packed wall to wall. I’m just thankful for how everything has worked out. If I ever do two plants per earthbound again I’ll make sure to veg for less time. I’m hoping to give these girls another week but the weather once again is going to be warm and wet so I will probably need to cut them down

Finally! Finally! First indoor grow of my life...feeling tense and so fucking happy!!! Read what there was to be read, got my Sangoma(guru-mentor or whatever you want to call him), need to get all wrapped by the 1st of feb. 2021 before moving to (again) new life. Wish me luck!😁

hello beautiful ones, they managed to enter flowering!! everything is going smoothly apart from a few insects... I think it's normal when you do them outdoors. They have been flowering for a week and continue to grow every day! DAJE ROMA DAJE

Grow very fast!

Hi legends, Day 47 of week 7 This week has seen a massive difference, 3 of the plants have started turning purple which I find strange as all the cutting were taken from the same mother plant. we also have a leaf with seed pod the same as Bnc grower, not sure what causes this anyone? but my guess is that she just wants to get germinated any way she can.. Have started to flush with pre RO water at ph 6.3, this is near impossible to ph with a meter at 0 CF, So I have to PH the water with PH 6. 7.6 colour chart. Also this week the buds are much more resinous and the aromas are fantastic, especially fruity with a very distinct peach smell. I also noted that IMO many smaller buds have not been receiving enough light and therefore not ripening as well, these will be used for making hash looking at the trichomes most still clear but on the purple plant they are mostly cloudy. Ttfn Greenies 😍

Wow she's grown 24cm this week. I'm getting excited about her! I think she's looking to be a fab plant. Doing well in her fabric pot.

Day 77 - Her flowers are forming nicely. Trichomes are forming! Starting to get stinky.

Pilot reaches week 6 with noticeably denser flowers and a strong increase in resin coverage. The buds are stacking well along the branches, developing solid structure while maintaining the plant's characteristic open architecture. Trichome production is now evident across both flowers and sugar leaves, and the terpene profile continues to intensify. This cultivar is showing excellent flower set and is entering the final fattening phase with great potential for quality and resin production. Seeds by World Breeders Cultivated by Piperoots 🇲🇦 🌱🔥

Easy trim✂️ The buds are super sticky & dense⚡️ The smell is Absolutely DIVINE,flowery sweet & orange🤤🍊🌸

Plant looking good, just observing the grow now.

There is nothing to report this week. The ladies grow diligently in front of themselves. The smell is now very strong - Dark berrie Explosion 💥 🤤 I'm so looking forward to the harvest! Next week I will change the fertilizer again. Feel free to give your opinion on my diary, I would be happy!
