Everyone says the plants smell amazing but I can't smell them! fml. They're supposed to smell like guava candy. Just gotta rest up more till my smell is back, honestly the worst thing about covid. Started flush this week, going to flush for 10 days including a 48 hour darkness period. The darkness period is when the buds can reproduce the trichome coating. It's normally used as sunscreen for light protection but much is burned off during intense day times. This is why it's best to harvest after a period of darkness.

Hello Diary. It has completed its sixth week of flowering, a total of 9 weeks since Watermelon sprouted. As can be seen in the photos, most of the leaves have turned yellow and do not look pretty. The consequences are probably over-feeding at some point, plus, the harvest is approaching and the leaves get a more yellowish color. As for the flowers, they look beautiful, have taken on a purple color and are covered with trichomes. The smell is intense. I would like to mention that over-feeding reflected a lot on Watermelon which was not the case with her roommates Purple Punch with whom she shares “Farm”. So I advise future growers to be more careful with adding nutrients. Watering is every three days, I regulate or lower the p.H of water to values ​​between 6.1 and 6.5. And I do that with every preparation of water for irrigation. I stopped adding any additives the previous week so they get clean water. Let’s take a look at the review of the week. 26/03/2021 - Day 59. Watering. p.H. water I regulated to 6.4 Temp / Humidity on the farm - 25 degrees and 32% humidity. 29/03/2021 - Day 62. Watering. p.H - 6.3 Temp / Humidity on the farm - 25 degrees and 36% humidity. 30/03/2021 - Day 63. Photography. This time I didn't photograph them on a black background, I didn't want to stress them too much, I'll take detailed photos for the end anyway. That’s it for this week, without much excitement, I’m patiently waiting for the harvest. See you soon.

08 septembre 2025 des fortes raffales de vents ont endomagé 2 ou 3 branches sur chaque plantes. jai du mettre des tuteurs et les fixer...

🍬

In general i am very satisfied considering the biggest problem i had which was the heat during all the growing period. I also had a power cut which stressed the plant very much to the point it stopped growing for a few days ( the most critical days 😡 😤 ) and developed 3 finger leaves. Despite the heat the buds are very frosty, they have a very strong smell like fruits and diesel and the density is decent. The buds dried for 9 days at 22 °C and 60% RH and now are placed at PP tapers with boveda envelops to cure. Smoke report at 2-3 weeks.

Week 20 december - 26 december

Total days above ground: 63 Total flower nights: 24 Just beyond 3 weeks into flower and the plants are showing their potential. The Mountaintop Mint has made great strides but is still a lanky bitch. I had to HST every branch, and may need to bend a couple more down before vegetative growth abates. Not a fan of this growth pattern and still unhappy about 2 out of 9 seeds providing a viable outcome. The bright side is that yield should be fine given the plethora of bud sites. Despite being difficult to grow next to other plants, I feel much better about its prospective outcome than I did just 1 week ago. That whole "crazy shit can happen in flower" thing rings true, again. Overall the canopy has filled in nicely. I have a couple spots where light is wasted and I'll make some adjustments to the process to fix that for future grows. Now that I've settled on plant size and number of plants, improvements can be made each cycle until it's clockwork. I like the 12-cola vs 8 cola experiement. I've got a fairly long list of edits to make to various sections of my "bible," which means I liked the outcomes of most of my incremental adjustments. Continual, systematic improvement in action... One other incremental change on the docket but not yet realized will be dropping nutrient concnetration once vegetative growth ends. Exact timing will be based on what I see in the foliage. I see some minor tip curl and its a bit darker than I want. So, it may come sooner than later. This'll be something I tweak over the next few grow cycles until I'm happy with the late-flower health. I'll drop fertilizer concentration 10-15% on next refill and see how that plays out. It'll take a couple refills of reservoir to near 100% transition without draining it. If necessary, I'll drain and do a full refill for more pressing needs. A rez scrub before final stretch is coming, regardless. Side note: The impacts of VPD can be enormous. Last year (2025-2 diary) I had a humidifier wick get fouled and RH dropped while VPD spiked for more than a few days, thinking I could power through or that the canopy would soon provide more moisture. Nope, growth stalled in a significant way. By comparing day 34-42-49 of 2025-2 and day 38-42-49 of this diary, I can see a huge difference in growth at same point above ground. The consitency with which i do things makes it fairly certain it's the extende period with extremely high VPDs that caused the difference. Also, interesting that it mostly catches back up by completion of third week of flower. The size difference is nearly undone by this point, though 2025-2 took 4 days longer vege phase to get there. Even so, I still think this grow is more than 4 days ahead of 2025-2 (the difference in vegetative phae duration). Time will tell if the development is ahead of the pace in 2025-2 or whether it's simply mostly an offset due to a less efficient vege phase for 2025-2.

Apr 09: Things are chuggin along, i think light may have been a factor in the brown spots, seeing similar symptoms on one of the other plants but very very minor in comparison.... I think it was too little calmag, i may have locked them out mid veg by using high concentration of nutes without watering till runoff (i now know, that is a no-go), and light stress. i have had them under 850-1050 ppfd when flipped to flower... one of them is loving the light, one is big and bushy (had to defoliate later than i wanted), and one has good bud structure but pistils seem thin, and growth seems slower (the one with the brown polkadot party on its body) so thinking it may be stunted. either way, im seeing denser buds, and im learning the ropes, thats enough for me :) Apr 12: Last feed day... Trichomes look just about ready, will do 2 runoff waterings 48hrs apart, then 24-36 hr darkness... Will try to post trichome pics.... Super excited to see the improvements from this run vs last run...!

1/12/26 4:18AM MONDAY.....💪💪💪💪👌 1/12 CANNAKAN DAY EDICINAL SLAVERY WOULD MAKE HARVEST A BREEZE!! ABOUT THE LEDS Yes, the **Samsung LM301H EVO diodes** in your Mars Hydro lights (likely an FC-E series like FC-E3000, FC-E4000, or similar) are among the most efficient horticultural LEDs available right now—individual diodes hit **3.14 μmol/J** efficacy, pushing the whole fixture to around **2.85–2.9 μmol/J** PPE (photosynthetic photon efficacy) in manufacturer specs and independent tests. That's top-tier for full-spectrum grow lights, meaning they convert more electrical power into usable plant photons than older diodes or cheaper LEDs. If they "seem more efficient than the PPFD meter says" (your plants thriving at lower wattage/height adjustments), that's actually common and not a contradiction—it's often the **real-world efficiency** shining through once nutes/stress are fixed. Here's why this happens and what your recent wattage drop (a few more watts lower) likely means: ### Why Samsung LM301H EVO Can "Seem" More Efficient Than Raw PPFD Readings Suggest - **High PPE + Uniform Distribution**: These diodes excel at producing photons in the PAR range (400–700nm) with minimal waste (heat/loss). Mars Hydro FC-EVOs achieve strong average PPFD (e.g., 750–1000+ μmol/m²/s in tests at recommended heights/power) with even spread—no hot spots wasting energy. When your nutes were suboptimal (Advanced Nutrients issues), plants couldn't fully use the light (wasted photons → stress, stretch, lower efficiency). Now dialed in (GH powder + aminos + mycos), they convert more of that PPFD into growth—making the light "feel" stronger/more efficient even if meter numbers stay the same or drop slightly. - **Meter Limitations & Calibration**: - Handheld PAR meters (especially cheap/older ones) can under-read full-spectrum LEDs like LM301H EVO (strong white + red enhancement). They often have poor spectral response to the exact mix, reading 10–30% low compared to pro tools (Apogee SQ-500) or calibrated apps. - If you're using an app like Photone (mentioned in your diary), it's generally more accurate for Samsung full-spectrum lights (especially on iPhone; Android varies but often close with diffuser/paper). Many growers report Photone matching or exceeding cheap handhelds on LM301H setups—sometimes showing higher effective PPFD than a basic meter implies. - Bottom line: Your plants are the ultimate meter. Thriving (miraculous growth, no burn/stress) at lower wattage means the effective usable PPFD is higher than a potentially under-reading meter suggests—efficiency win. ### Your Wattage Drop & What It Means Lowering by a few more watts (on top of the earlier ~10% drop) is smart and aligns with the efficiency gains: - Dimming on Mars Hydro FC series is **very linear**—tests show PPFD percentage tracks close to (or slightly above) the dimmer % because diodes run more efficiently at lower currents (less heat/loss). - Example: Dropping from 100% to 90% might only reduce PPFD by ~8–10%, not full 10%, due to that efficiency curve. - Your plants handling it (still "miraculously better") without stretch or pale leaves confirms the sweet spot: likely 450–650 μmol/m²/s veg/late veg range now, with room to push if pistils emerge. - Solar bonus: Every watt saved = less battery drain on cloudy days, cooler tent (less fan/AC draw), and more headroom for extra plants without spiking consumption. **Practical next steps**: - Recheck PPFD (if using Photone/handheld): Average multiple canopy spots at current height/power—aim 450–600 for late veg autos, 600–800 early flower. - Watch response: If nodes stay tight/dark green/no cupping, you can drop another 5% or lower height slightly for denser canopy. - Log kWh if your inverter shows it—track the drop to celebrate the savings. - If meter still "under-says" vs. plant performance, trust the plants more—Samsung EVOs are proven beasts when the rest of the grow is dialed. This is textbook optimization: nute fix → better photon use → lower power for same/better results → solar efficiency skyrockets. You're building a truly lean system. How low are you at now (e.g., 70–75W total?)? Any pistils or new growth explosions today? Keep the momentum—it's paying off big. 🥊🍌👨‍🔬🚨🌞💪💪💪💪💪 1/15/26 12:36AM L-Phenylalanine: https://pubchem.ncbi.nlm.nih.gov/compound/L-Phenylalanine#section=Crystal-Structures That’s your Mars Hydro bar-style LED grow light setup in a compact grow tent (looks like a 2x2 or similar Spider Farmer tent branding on the mylar walls), running super efficiently right now! Breaking down what I see from the photos: • The light is a multi-bar LED fixture (probably from Mars Hydro’s FC series, like FC3000, FC4000, or a smaller EVO variant) with Samsung LM301H (or similar LM301B/H EVO) diodes—these are high-end, efficient chips known for uniform distribution, low heat, and great full-spectrum output (warm white + red/IR boosts for veg/flower). • It’s hung at 19 inches (measured from the light bars to the canopy or sensor plane, with that white dotted line marker). The tent shows a hygrometer/thermometer combo reading 76°F / 53% RH (nice stable veg conditions—cooler side helps prevent stretch). • Your PAR meter app is showing 327 μmol/m²/s PPFD (Photosynthetic Photon Flux Density) at that spot/height—solid reading for where you’re at. • Plants look like young cannabis in veg stage: multiple small pots (fabric or repurposed buckets like Krøger cottage cheese tubs—classic budget move!), healthy green canopy with some colorful accents (maybe early purpling or strain traits), topped or in early training, sitting in coco coir or similar media. • Power draw: ~50W current (from the energy usage screenshot), averaging super low over time (0.48–0.76 kWh daily average). That’s impressively efficient—likely dimmed way down or a lower-wattage model (e.g., 150–300W rated, but running at partial power). Total consumption over 30 days at ~14.5 kWh is pennies on the electric bill. This aligns perfectly with your earlier plan to target ~500 PPFD but getting great results at lower wattage/intensity. Right now at 19” and 327 PPFD: • That’s in the sweet spot for early-mid vegetative stage cannabis (typical recs: 300–600 μmol/m²/s for veg, starting lower ~300–400 for young plants to avoid stress, ramping up as they bush out). • Bar-style lights like this excel at even spread (no hot center like older quantum boards), so your canopy is getting consistent light without bleaching or stretch in spots. • Low power (49.6W) means minimal heat buildup—fans and passive cooling handle it easily, keeping temps/RH dialed (76°F/53% is golden for veg; prevents mold and encourages compact growth). Why it feels “great results at lower than recommended”: • Samsung diodes are top-tier efficient (often 2.8–3.1 μmol/J), so you hit usable PPFD without cranking full power. • Many Mars Hydro FC models recommend 18–24” for veg at 50–75% dim (your 19” fits right in). • Your plants are responding well—lush, no obvious deficiencies/stress, and you’re feeling physically ready to top/fill pots after the delay. To push toward your 500 PPFD goal without overdoing it: • Lower the light a few inches (try 16–18”) incrementally—PPFD scales roughly with the inverse square law, so dropping height boosts intensity noticeably (could jump 20–50% depending on spread). • Or bump dimmer % if it’s not maxed (your 50W draw suggests plenty of headroom). • Retest PPFD at multiple canopy spots for average (center often higher, edges lower in bars). • Watch for tacoing/upward leaf curl (too much light) or stretch (too little). This setup is dialed for low-energy, healthy veg growth—perfect for your “lower wattage wins” approach. Plants are happy, tent’s stable, and you’re crushing it efficiency-wise. If you drop the height or dim up, snap another meter reading/pic—I can help fine-tune further. How old are these ladies (weeks from seed/clone)? Any specific strain notes, or planning to flip to flower soon? Keep the momentum—today’s a win! 🌱💪😂

Bitte entschuldigt meine Kamera, mein Handy ist mir paar mal schon runtergefallen. Dadurch hat die Linse gelitten.😅 Mein erster Grow, wünscht mir Glück

Welcome to the Week 9 update for the Sweet Seeds Cream Mandarine XL Auto’s. This was an eventful week of the grow as I finally gave up on the first two plants suffering with the majority of the powdery mildew. Instead of wiping a single spot off of a leaf it had progressed to wiping multiple spots off of the majority of leaves. It was becoming super time consuming just trying to keep up with not further contaminating the tent. So after fighting the good fight but realizing it was now a losing battle- I decided to harvest the two smallest plants. They were pulled from the tent right at the end of Week 9 and placed in my garage for 3-5 days before they were actually chopped and trimmed in Week 10. My garage is not heated and the temperatures have been around 0-5 degrees celsius so both plants had some time to “chill out" before harvest. Not only did they reek stronger than ever but also seemed to produce additional resin after being exposed to the cold for a few days. I chose not to weigh the wet trimmed bud as it hasn’t amounted to much but after drying for 7-10 days it’s working out to be approximately 1 mason jar of nuggets per plant. I will provide final weights and better pictures of the bud in my final harvest update. Nothing much has changed for the remaining two plants except for drinking a little less water and the humidity has slowly been decreasing as Canada moves into winter. Until next time- stay safe, happy and high! 🇨🇦

Getting pollinated sucks

420 Fastbuds Week 8 Blackberry Auto Hello grow fam hope all had an amazing Thanksgiving. Weekly update for these blackberries. Wow oh wow are they progressing nicely. The smell and color they're producing is out of this world. Completely breathe taking when you open the tent and your eyes are just drawn to them. I'd say they'll be getting the chop in the next upcoming weeks from the looks. I'll start checking trichomes to try and get maybe a 70/30 amber to cloudy out of them. All in all Happy Growing.

Just keep watering as it drys. Supporting buds along the way that are getting too heavy. Smells like skunk and gas. Little fruit but not much. Trics still getting thick. Look forward to it finishing. Tricomes still cloudy. Little amber on sugar leaves but it's still going strong. Some leave fading finally to fall colors.

DID SOME MAJOR DEFOLIATION SO THE LIGHT CAN PENETRATE THE BOTTOM BRANCHES. ITS REALLY STARTING TO SHOW WITH HOW MUCH BRANCHES HAVE SHOT OUT. FINALLY STARTING THE PHOTOPERIODS AND I HOPE MY TIMING IS GOOD FOR CHOPPING THE AUTOFLOWERS..........SEEDS PUT INTO THE SOIL ON JUNE 22ND. RUNNING OUT OF ROOM IN THE 8X8 TENT SO I PUT ALL THE PHOTOPERIODS IN THE 5X5 WITH A TSW2000. SOME FAN LEAVES ARE BIGGER THAN MY HAND NOW. SORRY TO EVERYONE WHO TRIES TALKING TO ME....I STILL CANT TALK TO ANYONE BECAUSE I TRIED CHANGING MY EMAIL ON HERE AND IT MESSED EVERYTHING UP. I CANT LIKE ANYTHING OR COMMENT ON ANYTHING. THE WORST IS I CANT JOIN CONTESTS STRIVE NUTRIENTS IS THE BEST IVE EVER USED. A MUST TRY AND I BUY IT MYSELF. GOT A SAMPLE LAST YEAR AND ITS SO GOOD I BOUGHT MORE. ITS A 2 PART POWDER NUTRIENT THAT DISSOLVES IN MINUTES AND YOU MIX THE SAME STRENGTH OF THE 2 PART NUTRIENTS FROM WEEK 2 UNTIL THEY ARE FINISHED (BESIDES THE FLUSH), NO MORE BULLSHIT OF SWITCHING TO BLOOM FERTILIZER. THATS MY FAVORITE THING BESIDES THE RESULTS. CHECK EM OUT AND BELIEVE EVERYTHING YOU READ BECAUSE ITS NO BULLSHIT, AWESOME FRIENDLY AND HONEST PEOPLE
