Grow Report Week 11: The Continuation of the Flowering Phase Hello dear grow community, We are now in the second week of the flowering phase, and the developments are exciting. All the ladies have stretched further and received their final lollipopping today. A little defoliation was also carried out to direct more light onto the tops. The Frosty Nightmare Challenge At the beginning of the week, there was a small problem with the Frosty Nightmare, but it seems not to be spreading further and was removed. I am relieved that we have it under control. Space Filling, Temperature Control, and Fertilization Scheme The area to be illuminated is now completely filled. The temperatures remain constant at 25°C during the day and 22°C at night. Relative humidity below 50 percent. The Biobizz fertilization scheme is still being followed 100%, although I have raised the pH value a bit to support the Cal/Mag uptake. Bud Development and Anticipation I am satisfied with all the plants; their bud development is promising. The next 2-3 weeks will surely be very interesting. Banana, Do-Si-Dos, Gorilla Zkittlez, Frosty Nightmare, Pink Rozay, and Girl Scout Cookies can now show what they are made of. I look forward to sharing the progress with you. Thank you for stopping by, and see you next time! 😊

Day 71, 19.06.2024 As the new and possibly last week of blooming arrives I am looking at two ladies, that behaved quite well during the last weeks. They grew close and it will be a shame to cut them down in the end. However, what must be done, must be done right? Today there will be the second to last nutrition intake for them. I decided to cut the BioBizz Grow and CalMag completely so they will receive 600ml of 4/4ml (Bloom/TopMax) later today. Also today I saw the first amber trichomes through my pocket microscope. But not enough yet - maybe I will stop feeding nutes after todays "last supper" and start flushing... Day 72, 20.06.2024 No action today. Day 73, 21.06.2024 600ml of water each - no nutes. I think it might be the big finale. I am thinking about harvest next and watching a lot of YouTube about that topic 😂 Day 74, 22.06.2024 No action on the plants but to give them a check up. I finally see the first amber trichomes on both of the plants, woohoo 🙌 Removed 3-5 fan leafs that were starting to get yellow. Time to make up a plan for the harvest I guess! Currently the plan is - to do harvest in 4 days from today in the evening (Wednesday, 26.06. ~1700). - I stop watering immediately - no more soup for you! Maybe I did not do flushing long enough, but my hope is that using organic fertilizer eases the effects - I will not switch off the lights on Monday at 1100 (like usual). Instead I will keep it on until 1700 - then switch them off completely. - 48h later on Wednesday I will harvest I do all this to inflict stress to the ladies. Stress by low water, stress by longer light followed by stress due to no light at all. All this will hopefully lead the plants to 1. produce more trichomes as a defensive reaction and build up bud mass 2. urges the plant to process as much chlorophyll as possible which leads to better taste in the end So much for the plan. Let's see how this turns out. Day 75, 23.06.2024 The good thing about not watering anymore: No action today. But as today would mark the "point of no return" in a way I will double or even triple check for the trichomes. If they are ready, I will commence the plan of not watering and longer lighting tomorrow. If there is doubt I will shift the plan day by day. Aaand here it is: Doubt! After checking the trichomes again I found too much of them clear. I decided to not rush things and thus postpone the harvest for at least 3 days. So today there will be a (late) flush and we will take it from there. Day 76, 24.06.2024 No real action today but to check in trichomes. Erika II has a good number of amber trichomes while Erika I still has too mich clear ones. It's a dilemma. But I will hold on to the plan for now which says: Harvest will be on the weekend (friday presumably)! Day 77, 25.06.2024 Today we reached 30°C outside and it is (finally) getting summer here in germany. This resulted in 28°C inside the tent & it felt good to give the ladies some craved water: ~1000ml went in the pots before the drain started. This was definetly the last drink. Tomorrow the last light cycle will start. Today is tuesday. The plan for harvest is as follows: Wednesday: No action. Thursday: Lights out at 1100. They stay off until the end. Friday: Harvest will begin at around 16:30 after work. Both plants will be harvested & hung up for drying. I am thinking about doing one plant using wet-tim and one plant using dry-trim techniques, just to have the comparison right after the first grow. I guess I need to make up my mind about that...

The smell on this one is next-level for real! I got 2–3 different phenos, but they all carry that same loud scent I’d describe it as sweet and fruity I honestly can’t wait to smoke it, and judging by the insane layer of trichomes she’s rocking, I already know she’s gonna hit hard.😝😝

hello some news on vegetation day 22, start the bio grow, and bend the four Lateral head, and crap when i bend a stem has cracked but she is not cut I straighten them with a piece of iron she can go back. 😀👍

7th of May Day 59 day 11 of 12/12 4 plants are looking healthy the stretch has started and and the canopy is starting to get a bit dense I may rom I’ve some large fan leaves on day 14 of 12/12 to give better airflow and allow for the lower growth to get more light, I can picture the colas already 😁🍁 ppm still going in at 650 ph 6.5, i top dressed each plant with fish blood and bone mean 3 table spoons to each 3gal pot on day 1 of flower

16. Günde ilk besin takviyesi 1 litreye 0.5 ml olarak alga grow karıştırılıp 90ml sulama yapıldı. 19. Günde 90 ml boş sulama yapıldı. Yaprak oluşumu ve boy uzaması gözle görülür derecede.

We got some drizzles this week and some cloudiness, but her southern facing aspect, helped her out with getting some nice sunlight despite the fact. Temperature still dropping as to be expected so I didn't have to water more than once. The buds are swelling and frosting up quick.

I think the harvest is just around the corner here too. I'll give them another week at most, but I think they'll be ready to be cut down in the next few days.

Humidity was 25-35% so the buds were smaller than they could have been but that’s winter for ya. Other than that the plants is amazing. Grew very fast in veg and the buds smell fruity/ oranges. Great sativa high that feels relaxing and stoney. Pretty powerful.

Para ser mi primer cultivo . encuentro que tuvo un excelente resultado . las cepa escogida me dejo muy conforme con los resultados y la produccion obtenidad en un espacio de 1x1x2 con 300 watts de luz encuentro que estuvo muy bien . Muy contento con el efecto relajante y medicinal del la cepa , era lo que estaba buscando y lo encontre. / To be my first crop. I find that it had an excellent result. the chosen strain left me very satisfied with the results and production in a space of 1x1x2 with 300 watts of light I found that it was very good. Very happy with the relaxing and medicinal effect of the strain, it was what I was looking for and I found it.

Defoliated and trimmed lower fluff from The plant day 20 flower , Lots of air and light can now get to the plant and hopefully grow some nice buds

10/16: She is basically already done. I changed out the nutrients for water and Flawless Finish today. She is now flushing. I have been so surprised by this plant. She entered flower and finished quicker than i expected. I will be harvesting her this time next week. I am not blown away by the smell. i expected it to be more fruiting and sweet, but it just smells mostly earthy at this point.

Seriøst ér @KANNABIA BARE MIT NYE MÆRKE UDOVER @ZAMNISIA SÅ TROR JEG HAR FUNDET 2ud af de 3 frøbanker jeg HAR LYST TIL AT ARBEJDE MERE MED (hvis det er de ville 🖤🧡💙🛐☮️🧡🖤💙💚🔥😇👌

This week was hottt Record breaking temps wer cooking my girls sooo I let them out. I took out their light also (saturday) I also put green celophane on all the house windows (that dont have blinds) because i dont want the house lights to disrupt their sleep. ( i dont know how sensitive they r ) Next week will be their first full week of flower

1/12/26 4:18AM MONDAY.....💪💪💪💪👌 1/12 CANNAKAN DAY MEDICINAL 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! 🌱💪😂
