In the bag ladies. HID on 600W now, Airtube on the floor, first time I do this so I just bought it. I install it, don't feel any air coming through any holes, I call the store and they give me this: "We ran out of perforated air tube, you need to poke some holes yourself, we'll refund it" 😂 I mean, what! No time to waste so I did poke holes myself but..man! In-fan was running hot obviously. Glad I caught that on time. Feeding to 1.6 EC, one shot of enzyme this week, rootjuice. first watering with Aptus Soil Attack to prevent soil critters. 15 liter bags with Biobizz All Mix (I ordered Supreme but hey...ffs) Can't go wrong with Biobizz though. This is going to be a short week probably because I want to switch to 12. Just want to have the roots settled in their new home and then B(L)OOM!

Beginning of week 3 of flowering and plants are slowing there stretch down. I decided to let them come up into the second screen about a foot above the first screen. Second screen holes are twice as big as the first layer screen and is primarily to support the colas later in flowering. I stripped all the growth below the first screen so the plants won’t waste there energy on these lower beaches with no light under the canopy. I will be removing a few of the larger guard leaves later in the week on the top of the canopy to let light in to the lower shouts ready to come up, but not until after the plants recovers for a day or 2 from the bottom stripping. Smell is starting to ramp up, can really notice it strong when you open the tent now.

The plants are really starting to frost up, definitely starting to smell. I’ve got my carbon filter running to keep the house from wreaking.

Bueno resumiendo cookies gelato es una variedad híbrida muy fácil de cultivar pero ojo, cuidado con los últimos riegos si no queréis perder cosecha por moho. Lo demás de 10 pegada heavy sabor increíble, cogollos duros como rocas y bañados de una gran capa de polen. El ambiente del secado se mantuvo en 23 grados de media y la humedad estuvo por debajo de los 45% en todo momento. Poco más la verdad estuve encantado de poder cultivar una genética tan potente . Un saludazo que paséis un final de año increíble y por supuesto buenos humazooos💨💨💨.

Hey now! This week went pretty well, I did notice my EC of my runoff was getting pretty high on day 65, it got up to about 1.9, and my nutrient solution going in was at 1.6. I ended up mixing a bucket of my normal fertilizer, and hand watering all the places my drip ring wasn't really hitting, and i got the EC back down to about 1.7. I also got a tip from MrJones to setup some type of support for the colas. I ended up tying some 550 (parachute) cord across the top of my tent poles, then I ties little loops around the colas with the same soft cord. I then used wire ties to attach the loops to the 550 cord. I also am slowly reducing my EC, as I believe I only have a couple weeks left. I am also going to be switching from Liquid KoolBloom to Dry KoolBloom at some point later in week 10. If anyone has any experience on the correct timing of this switch to ripening formula, please hit me up! I am still struggling a bit with heat and humidity, and am considering buying another dehumidifier for my next grow. As always, Thank you to everyone for all of your encouragement, support and tips!! Blaze on!

Start of week 5 today, everything seems to be going great! The Gelato OG is by far the biggest plant of the bunch so far but they all seem to be taking well to LST, HST , Topping & defoliation! Will be going in the flower tent as soon as the other ladies harvest so they will probably have atleast 2 to 3 more weeks of veg!

Day 61 - April 11, 2021 Today was full of headaches lol. Checked the PH of the reservoir this evening and it had dropped to 4.6. Algae exploded in the past day. Removed reservoir and pumps and cleaned thoroughly. Thankfully just prepped a new batch of nutrient solution. Humidifier hasn't had to run all week. Will be switching to dehumidifier soon.

It's randomly reset 2x over the last couple days. At first thought it was a fluke and maybe bump the reset button somehow. Seems unlikely, it randomly resets clock to 12am and erases the programmed times. Think I'm going to give a smart plug a shot instead (at least I can see notifications if scheduler fails) So far seeing pistols on all ladies. No nannards so far.

Waiting for Anden dehu to arrive. Also replaced the Titan Apollo 9 controller for water pumps as it keeps randomly resetting and has proved unreliable. Testing a smart plug and will create some conditions with IFTTT to send notifications to ensure pumps don't miss schedules, shut off correctly, etc. Plants are doing well. Pistols are popping out faster and faster. Planning to do some canopy management this weekend and will be inspecting to make sure there aren't any pollen sacs forming.

Flipped to 12/12 a couple of weeks ago but the flowers are just now starting to form. One of the plants turned hermie out of nowhere, I really don't know what happened. Also the lower leaves are turning yellow and I think it has something to do with the pH because I think I added too much calmag but other than that they're doing their thing.

03.09.25 BT#5 Servus liebe Growmie's alles fresh bei euch der Roswell Code geht es wunderbar voll in umgestellung auf die Blütephase. Lasst es mich kurz sagen Super Performance, Sie macht sich sehr schön Ihre seiten Triebe sind da wollen Gas geben der strech wird bald beginnen. Der Hesi TNT Complex wird langsam runter gefahren Hesi Blüh Complex geht mit an den Start. Den PH wert habe ich von 6,7 auf 6,5 runter gefahren da jetzt primär andere Nährstoffe zur Verfügung stehen müssen. Der Ph wert wird vor der Massephase der Buds wieder um 0,2 runter gefahren da beträgt er dann nur noch 6,3. Jetzt muss Sie noch ein wenig Zeit brauchen bis dahin halte ich euch weiterhin auf den laufenden. Bleibt alle Cool 😎 dont worry be Happy stay High and chill. Danke für den halt mögen all eure Ladys Gesund und prächtig wachsen und euch mit schmackhaften Stuff versorgen 👌🍀 ■■■■■■■■■■■■■■■■■■■■■■■■■ 03.09.25 BT#5 Hello dear Growmie's all fresh with you the Roswell Code is doing wonderfully well in the transition to the flowering phase. Let me say it briefly Super performance, she is already doing very well her side shoots are there want to give gas the stretch will start soon. The Hesi TNT Complex is slowly being reduced and the Hesi Bloom Complex is also being added. I have lowered the pH value from 6.7 to 6.5 as other nutrients must now primarily be available. The pH value will be reduced again by 0.2 before the buds' mass phase, when it will only be 6.3. Now she needs a little more time until then I will keep you up to date. Stay cool 😎 dont worry be happy stay high and chill. Thanks for the support, may all your ladies grow healthy and splendid and provide you with tasty stuff 👌🍀

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! 🌱💪😂
