Great nose and terps. Cookies beats out Humboldt in quality. Yield was very low but that could have been growers error

This week has been wonderful, she's really coming into form and I'm loving the structure of this tester! She responded very well to the simpro bloom formula and I'm really excited to see this grow through! Hoping for something similar to the cream cookies from last grow! Below are days of activity for this week: Day 38 Adjusted LST Day 40 1 gal distilled water 5g bloom ppm 517 Pulled 7 leaves Day 43 1 gal distilled water 6g bloom ppm 582 Hope everyone has a fantastic day! Happy growing

The first thing I did was disinfect everything and put it in the shower. Then I calmly rewired the tent and filled the pots. 20% clay balls at the bottom as drainage. On top 50% Biobizz All- and 50% Biobizz Lightmix. I mixed the whole thing well beforehand. 3 seeds came out great, one is currently fighting through and I don't think anything will happen to the last. I planted them all today. Let's see if the last one can still make it.

Note: Little chem-burn this week. Feed just water for 4 days with correct PH and they jumped back. Was not that bad though. Day 21 on flower!

Day 79, 28th of November 2020: Hi there! Here we go let's say half way. Plants are pretty these Original Sensible Seeds genetics are fantastic! The 2 OG and the Runtz Gum is very strechy. Black Ghost is pretty shorter bushier plant. Runtz Gum and Do-Si-Dos OG approx the same height Do-Si-Dos OG is taller a bit. Wedding Gelato is really cool little, bushy anf nice buds forming not problem with her all she is quiet. Do-Si-Dos OG has some deficiency and leaf gets dry but nothing very serious..... Fertilization is still the same every second day with the rationand mixture above stated. The lamp is on 11.15 min and off 12.45 min. Last week was 15 min longer light cycle.... So every week 15 min shorter light cycle until the 5th week. So far -45 min. It switches on at 6 am and off at 17.15 pm.

Day 58, 7th of November 2020: The 6th day since the lamp switched to be 12/12. I raised up the nutrition intake as it can be seen above only the BioBizz family 2ml/l and removed some LST because the plants remain in shape or just set a bit but nothing significant.... They look good and strech is on the way..... These Original Sensible ones are having really nice smell :) Nothing really to report there is crazy 2-3 weeks from now ;)

Week 2 begins for Green Crack and LSD. Both ladies are looking happy and I increased their feed by 1 liter each. Thanks for stopping by growfessors 👽 tune in next week for another episode of growfessor theatre.

Vamos familia, actualizamos la quinta semana de vida de esta Amaretto Tarmac de Seedstockers. Empezamos abonando ya con varios productos de la gama Agrobeta. Temperatura y humedad dentro de los rangos correctos, 18 horas luz, 6 oscuridad. Una lástima que de todas solo aguanto una, aún así seguiremos con el diario hasta el final. Ya trasplanté a sus 7 litros definitivos. Agrobeta: https://www.agrobeta.com/agrobetatiendaonline/36-abonos-canamo Hasta aquí todo, Buenos humos 💨💨💨

1/12 4:14AM MONDAY!!!!!!!! CBG IS GOOD!1 LOWERD THE WATTAGE, EFFICIENCY IS GOOD. GREAT WHITE MYCO HAS INCREASED UPTAKE AND AND!!!! PHOTOSYNTHESIS EFFICIENCY ......FUCKING AWESOME 💪💪💪💪 1/12 4:47AM I asked GROK: are samsung leds on my mars hydro lights seem more efficient than the PPFD meter says, I lowered the lights again by a few watts? 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. 🥊🍌👨‍🔬🚨🌞 1/13/26 7:47AM BRUTAL WEEK FOR THE MOP AND BUCKET GUYS AT MUDRUROS COMPOUND 1/13, 11:22 AM banana purple punch auto RF three is doing really great. I haven’t really needed to do anything. I decided not to top. I didn’t want to do anything except light stress training. I think she’s gonna turn out just great. Her stock is one of the thickest. She’s just perfect.😍😍😍

So far I keep training back the branches to keep the tops even, they’re responding well. I might top the middle plant this week if I am going to top her. Kicked up the base nutrients and added in a few root boosters and bud dandy to prep fo flower. I’m probably 2 weeks from flowering, but I should be transplanting near the end of the week and moving into the flower tent a few days later.

È arrivato il momento di pulire i boccioli delle ragazze di @anesiaseeds che sono fenomenali con dei fiori gelidi, pieni di resina, un ottimo profumo che ancora dovrà migliorare nel tempo…cercando di fare una buona concia che è sempre importantissima nel processo di guarigione per avere un fumo delicato e non pesante per la gola, questo fumo è già ottimo! Ottimo lavoro Anesia Seeds
