Extremely disappointed with the yield but that is my mistake by keeping this 100% indica from getting bushier and expecting it to stretch more. Definitely many lessons learned this grow. Going to add weekly flushes with beneficials in my next grow schedule from now on.

Rolling into week 3 from seed roots are starting to drop through the net cups and down into the solution. Growth appears to be a lime green color, which would indicate that they are in need of more Nitrogen (N). One is struggling to keep up with the others and is looking a bit mutated and is not responding well to the nutrients I am using. I am going to add some 5.8 pH water to her rez and see if the dilution helps. Over all happy with the progress so far, Will post again next week with new progress.

Sour Jealousy Auto FastBuds 2025 Outside Grow April 13-19 Veg week 2 Well, my little girl survived the drop in temperatures last week but the cold slowed her growth and development. The weather is returning to our seasonal temperatures this week. Low of 39 at night and high of 87. Looks like Spring has come to stay. 4/19 pics taken, including a garden visitor. No, he did not crawl into the pot, I put him there, then put him back into the garden. Your likes and comments are appreciated. Thanks for stopping by. Growers love 💚🌿 💫Natrona💫

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! 🌱💪😂

Hello growers and tokers! 👋 👩‍🌾 🧑‍🌾.🔥💨 Hope you had a great week because these ladies sure have! 😍 They're starting to get that sweet aroma this strain gives off, her aroma will be over powering my tent in full flower. Love it! Pictures and info were taken on day 12 of flower. I put 71cm tall because that's the average between the three girls. CC 1: 78cm CC 2: 68cm CC 3: 68cm CC 1 is killing it with the double main colas. 💪 💪 🤩 CC2 is my favorite. She's got a perfect shape, nice evenly distributed canopy. Took LST great. For me that's the goal when I do LST. CC3 doesn't fall behind in any way, she's looking great. There's a bunch of new growth everywhere so after 21 days i'll be doing some pretty heavy selective defoliation. Feeding 1,5L each, every other day. Will be increasing as they ask for more. How do they ask for more? When feeding if the soil is drier than normal I give a 150-200ml increment of water. I do that until they stop feeding so much then i just maintain that amount. I start reducing if it takes longer to dry. That works good for me. The old finger in the dirt trick. 👍 Nothing like knowing exactly what your ladies need first hand. They've got a lovely green lush color. It's a delight growing this strain. I'll have to get me some more seeds for next run because this is a strain that will always have a spot in my garden. 😍 😍 Hope you enjoyed this week's update and stay tuned for next week. If you like what you see check out the other strains in the garden. 😁 Take care and stay safe! One love!

Day 69 (March 6th) Just gave everyone their last watering. I’m going to harvest and wash everything tomorrow night on day 70. I‘m not going to do that whole 48 hours of darkness thing because I didn’t see a difference last time I did it. In fact, it made my plant under watered before drying which caused it to dry too fast. Slurricane and cheese will be washed with h2o2 and the rest will just be rinsed off in warm RO water and hung up. Before and after washing I’m going to go over each branch with a flashlight and make sure there is no dog hair or debris in or on the buds. I will be drying in my spare bathroom (that no one uses!) from hangers. Aiming to keep it around 60-62F and 50-60 RH. Hoping for that 10-12 day dry. I wanted to do a full plant hang but the tent got pretty dirty and I would feel more comfortable just cutting and rinsing everything off branch by branch. I’m going to try my best to keep the full plant intact. Got my humidifier hooked up and running RO water because with tap water it deposits calcium and lime all over the buds and walls. For air flow I’m just indirectly running a small usb fan. I’m not worried about air flow in the bathroom honestly. It stays nice and breezy down there anyway. Got the food grade peroxide and RO water to wash up the slurricane and cheese. Everything except for the cheese and garlic#1 is looking more than done. Trichomes all look pretty well done. Some of them have even burst open. Smells are all super ripe and mature too. Can’t wait to smell each individually in jars. Next week I will recap what went wrong and what I will do differently next time to keep it from happening again. (Day 70F) Just got everything chopped, washed and hanging. The vast majority of the PM was washed out but I can still see very small amounts. When they dry out I can shake the branches a bit to get the rest off. At very least it’s sterile now. There is no question I lost some potency while washing but the amount is negligible for a much cleaner product. I could see lots of dirt and other debris float to the surface of the water after being washed. And no those are not trichomes, those sink to the bottom. I could put that nasty water through a bubble bag and wouldn’t get all that much. Although it probably does remove a lot of the actual trichomes heads. I’ll have to check with the microscope. Everything is rigged up for a nice slow dry. Temp is sitting at 64 and RH is at a nice 60%.

12/30/23 - Day 54 - Hello All! I started this week a day early. I wanted to update everyone on something I have been thinking about a lot. Curing. I feel if there was a hole in my growing skills it would be curing. Last grow there was more than I had anticipated. I was not set up for curing 1 lb. I threw in an audible at the last minute. It worked out but I know I can improve with some trial and error and hands-on experience. So after reading a ton, and going off of some of my prior builds for drying, I came up with this design. I have a controller that will turn the air on and will run when the contents inside the box hit whatever RH% I want to set it at. I think the first week I will set it for 78%RH, then every couple of days go down a % until I hit 62%. The thought is that if the bucket gets above the set RH% then the air will kick on and distribute air across the buds until the RH% is back down to where you want it. It will force the humidity out. I won't need to worry about burping. It will happen on its own.... in theory. Ill update tomorrow with some pictures after the water change. 12/31/23 - Day 55 - Everything is looking good. The water change completed this morning while I was in the shower. Its adding nutes now and will do so over the next hour or so. She is starting to get stinky. I had to add the extra carbon filter to the room. I've got some pics up top of that. Happy New Year! Next time I post it will be in 2024! Have a great night and be safe! Dont drink and drive, your life and anyone else involved in an accident is too important! C' YA! 1/4/24 - Day 58 - I have been thinking of trimming her for a while.... I got a comment on the bushy-ness and I got self-conscious and gave her a trim. Lol I have been going bath and forth for a while and that gave me the push to give her a little trim. She looks great and is growing really quickly. Ill update with more pics as it goes along.

Hi Growmies, I topped her towards the end of this week and removed two sets of fan leaves. It opened the plant up very nicely in combination with the light LST I applied earlier in the week. The plant is taking very nicely to the LST and didn’t seem to care about the topping either. I attribute this to the strong root system she already has. For the next week I have fed her additionally to the canna nutes, some plant success orca, for healthier roots and Rezin from greenplanet to prepare her for pre flower. Here is the code that’ll give you 20% in Zamnesia‘s online store, just input ZAMMIGD2023 at checkout. Thanks for stepping by and until next week!

Start Woche 4 Blüte. Leider vermehren sich die Trauermücken gerade wieder🤐🤐🤐 Bis die SF Nematoden da sind gab es vorsorglich etwas Neemcake als Topdress.. Dienstag gibt's dann nochmals SF Nematoden und ich hoffe danach hab ich dann Ruhe. Zähes Pack😠 Blütetag 23 Die beiden bekamen heute nochmals je 1,5l Wasser mit SF Nematoden. Blütetag 25 Nochmals je 1,5l Wasser mit SF Nematoden.

The plant looks super bushy and also very very strong and happy, she's growing super fast, and she's also enjoying life man, really happy to see this lady enjoying, she has been mainlain ed by removing the main stem and allowing the 4 secondary low ones to become the main ones, after that she got topped on each main apical and that's how we have now on week 9 this beauty, a fat runtz muffin bush! 😍

Great. Week. No signs of mold or pests. Seeing plenty of lady bugs still and this is now almost a month after I first released them. Seeing some dragon flies and assassin bugs too. Niceeee Plants are doing super well. No deficiencies with plenty of swell occuring. More in some than others. The zkittles phenos that flowered early are almost ready. Maybe one more week or less.

The temperatures, humidity, and watering volume(if measured) in grow conditions are all averaged for the week. The pH is soil pH. Any watering done by me is well water which is 7.6 pH and 50° F. Any listed nutrients are ml/gallon of soil. Day 1 we had sunshine and clear skies until the afternoon. We had clouds roll in and about 4:00 P.M. a severe thunderstorm hit. There was high wind, heavy rain, and grape sized hail. Fortunately the hail lasted only a few minutes. Day 2 we have clear skies and sunshine. The temperature is mid 70's. Day 3 we had rain and thunderstorms through the previous night and into the morning. We had sunshine, clear skies, and temperatures in the upper 70's. That was followed by severe thunderstorms, rain, and a touch of hail from 4p.m. to 6p.m. These were topped and had thr bottom nodes removed. Day 4 we had relief from the rain. Temperatures were in the mid to upper 70's and lots of sunshine. We have a few days of sunshine in the forecast 🙏 Day 5 we had lots of sunshine and clear skies. Highs in the upper 70's and 49% humidity. We needed the dryness. 🙏. Day 6 we had clear skies and sunshine. Temperatures were in the mid to upper 70's. Day 7 we had partly cloudy skies and temps in the middle 70's. This week was a success. The plants doubled in height and thankfully didn't have any serious damage from the hail.

Day 43 - growing very well, preflowering a. defoliated some of the under runt growth b. bumped up the nutrients to my preflowering blend, 850ppm in DWC now, offsetting the measurements based of what is already in the res. c. PH is 6.5, the plant is liking the dwc, very similar growth to West Coast OG d. Fastbuds specifically recommends 6.5 PH for this strain, we are following directions e. performed some very light LST to the outside branches Day 44 - the very light LST is great a. the plant is really stretching out b. there are going to be many colas Day 45 - drinking alot of water a. growing very well, vegging hard b. added 4L to the DWC, 1000ppm Day 46 - she is stretching upward a. everything is going great, I love Fastbuds! b. when all other breeders are failing us, Fastbuds shines through Day 47 - growing well a. all is well in the world with our plant! Day 48 - growing well all over a. she is stretching upward, lowering the light a bit to encourage even more growth, 45cm away Day 49 - what a monster! a. all is growing well, in Geneva for the week, my grow partner is sending photos to me!

another uneventful week. the girl is still creating nodes like crazy ... she is growing sideways rather than rushing for the lights. i raised the lights higher to about 12" from the top of the leaves. i also changed the nutrients from a seedling recipe to an early growth stage recipe that is richer in nitrogen with a higher ec 1.2. i also got to see the roots for the first time, they are looking really nice - white and fuzzy. i made the main nutrient tank more permanent and relocated the used nutrient and fresh nutrient tanks in their own chamber so, it's even easier to do manual nutrient changes (1 container in and 1 container out sort thing). later on, in the week, i noticed the main roots showing a little discoloration, not sure if i should be concerned about this, but she looks healthy.. it was fun using the doser again as i really hate mixing chem's since my days in chemistry labs. looking forward to new aggressive growth this week.

End of the fourth week of flowering. The stretch being finished and the buds starting to grow, I added a little PK 13/14 to the OG Kush soup. The buds start to look like good big sausages ... A bit of defoliation here too to let the LED lights illuminate the buds of the lower floors.

ya se comienza a sentir un olor intenso, como se tenia previsto las black jack estan evolucionando sumamente rapido, ya comienzan a explotar en resina.
