After germination they stayed in the "green house" for the first week, but now under 20/4 light with 2 18W LED strips. With the lights on, temperature and humidity were in good ranges afaik. I installed a webcam above the plants that takes a picture every 30 min. which enabled me to create a (somewhat shaky) timelapse video (see above). They moved to the their (final) 4L fabric pots today, which are filled with a layer of clay balls and "potting and herbal soil" mixed with 10% fresh worm humus. From now on, lights are switched to 18/6 and I plan to continue watering with 10% worm composter liquid.

Last week the plants grew looking very healthy although I still have a feeling the low humidity is slowing their growth, by the end of the first week I started raising the EC to make the increasing for this week smoother, run-off EC is substantially increasing so I will start to fertigate them twice a day for this week.

Hi there, We have definitely seen some good growth since last update. Patient and the longer veg period paid off as many bud sites appeared. I mean 4 plants filled the whole 120*120 tent. Genetic traits are starting to show. Marshmallow Og has thicker stems and has grown taller during the stretch while Candystore RBX is a much darker green has a medium-long internode spacing. It was necessary to use a plant trolley to lift the Candystore for a uniform canopy level. The tallest Candystore is 67cm, Marshmallow 73cm. On day 21 after the switch to 12, I took off a bunch of leaves to get more light on the lower nodes. At first I was afraid I had gone a little too far because I had also done an aggressive lollipoping on these girls. Next week we'll see how offended they are haha. They became hungrier and we started supplementing their watering with the Booster. The above mentioned units except the Silica are grams not ml. They drink like 5 litres every four days. Running the light on 80% , 44 cm above the canopy. Par.: 540-770 Ppfd Vpd.:1,05-1,2kpa. Happy with how everything looks, until next time.🌱🌞

Gran experiencia como siempre Contento con el resultado y con ganas de seguir probando y experimentando en este gran mundo. Cultivo facil de inicio pero que a finales por culpa de una plaga que no supe tratar a tiempo y sus consecuentes caos en esas dos semanas ... Fueron en la 4 y en la 5 semana , y desde ahí , pàrecio que cause unas carencias que ya se lastraron hasta el final del cultivo ... Aun así , en mojado pudimos sacar , nada mas que 530 gramos , y que ya luego en seco antes de pasarlas a los botes el peso total fue de unos 190 gramos de flor seca y ya lista para ir curando..

Week 10 Flower week 4 Flower-day 1 05/11/2025 Nutrients change Floramax veg1 Floramax Organabud Floramax flowering enhancer Floramax Rezin Cyco platinum series silica Green planet bud booster Complete grow cal mag ( sensi unfortunately got refunded so got this instead today ) Sleeps with the fishez ( hocI ) Ladies are looking good overall, let the fun goodness begin i guess 😂 7/11/25 Blockage within systems finally fixed after 4 flushes. Not exactly sure what it was but whatever ive done has fixed it for now 🤷‍♂️😂 take it as a win for now i guess 11/11/25 Unfortunately I hate scrogg so took it off but once I had spread her out again with lst, I noticed that shes struggling with lower growth. I saw this with my autoflowers. I'm not too sure if its from too many budspots,colas or if it's just from being overpacked. So her pisitils showed up on the 25th, some people count from that date as flower and some count as soon as you flip, I've decided to go of the 25th as first pisitils so its only 3 n a half weeks currently. I decided to take a few branches and a few of the lower budspots to try and help her even herself on where shes taking her sugars and growth. No Defoilation, just 10 or so budspots n only 3 branches. I DONT NOT RECOMMEND doing any of this, I'm only reattempting this because it worked on autos I had going. I do think I've made the right choice Grape og is meant to be a pretty hearty and forgiving strain, so she should bounce back pretty quickly Oh well. I'll definitely be rerunning her again later in future but trying a different method

Welcome back✊ Outdoor season is finally showing the labours of love with buds a plenty. Can you feel the excitement? 🙌 Big time aromas in the garden this week are really quite something.👌 Everything from bananas and grapes to sweet & sour citrus and even dirty diaper. What? Yup that's right...My Blue Fire's smell like 💩 just like the clone mother and she's pure FIRE!!! I've grown this strain indoors but this is my first time growing it outside so I'm really looking forward to the outcome. 👍 Sept.14 the girls are putting on some serious weight. Colas are fattening up nicely but with that extra weight I’ve had to add more support and netting. 💪 Sept.15 last night temps got down to 8 celsius (46F) and today's high was 20 (68F). It's supposed to get even colder by the weekend followed by more average temps next week. Please God No Frost.🙏 Sept.16 Warmest day of the week at 25 celsius although very hazy probably due to the wildfires out west. Prayers for y'all out there. 🙏 The garden is looking amazing today with buds fattening up everywhere. Strawberry Banana #1 in front of the wall is furthest behind as far as bud development but is the tallest of the bunch at over 10 feet.👆 Bless that momma👏 Sept. 17 and just my luck Trainwreck #1 has a bit of bud rot on the 2 big main colas.😠 Damn I babied that girl and kept her dry her entire life. WTF Sucks having to harvest her early but shit happens so the 2 colas got chopped this morning and are hanging to dry. On the bright side, one of the colas wet weight was almost 11 ounces. Sept. 18 & 19 overnight temps got down to 4°C luckily no frost. Sept. 20 and most of the potted girls fan leaves are starting to yellow. Good sign that they are using up their last bit of nutrients from the leaves themselves. I’m guessing 1 or 2 more weeks and my first round of girls will be getting no more nutrients and starting their final flush. Trainwreck and Blue Fire are the furthest along while the wall girls are a couple weeks behind especially Strawberry Banana. That’s it for now Til next time... Be well and see ya soon

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! 🌱💪😂

Week 1 of flowering. These plants recovered quickly since the last defoliation. Probably gonna do some light defloration on day 14. Feeding with an npk ratio of 5-5-10. Using molasses, humic acids, amino acids, silica and kelp as a compliment. I'll cut out Silica and kelp around day 14. Greenhouse feeding Short flowering 663ppm PK booster 139ppm Calcium 260ppm

Day 49 Flip day! Just flipped them to 12/12 took loads of leaves off. Let's see if I've guessed the sex right then 😏 I think I've got 3 fems but people still tell me I want know until I've flipped 🤷‍♂️🏼 Update: Day 50 and day 1 of flower looking very happy will give a nice feed when soil dries out. Lights are now maxed out and on Day 51, day 2 of flower I'm sure all 3 are definitely fems will keep eye on them next few days 👀 Update again: Day 53, Day 4 of flower and they looking beautiful 😍

This week has been great! Germination on all 4 Pre 98 Bubbas and 2 Dirty Blondes was a success!! We planted them in there pots an through out the week we gave em each a very light spray down of pure water phd at 6.5 and by Friday they all popped out the soil Let’s go!!!!! Next week we will start light feed on nutrients , so y’all keep them eyes peeled for next updates an I appreciate y’all for following my grow !!😶‍🌫️💨💨💨🙏🏻💚💯🤙🏻

So this week the little gelatocake is on week 8 and is really starting to eat herself now, full of trichomes and smells like tutti fruity chewie sweets. Last week of nutes for her then mollases only. Week 7 for the othere gelatocake and shes starting to fatten up now as well as fade also. Babys have got big since re potting I will.bend them over later. Sherbert mimosa are still taking there time I think they are starting to get bigger 🤔🤣 I Will keep you updated lol. Happy growing guys 👌💪💚

Day 22 - All ticking along nicely...apart from a smart timer issue the last 2 days!!! :/ At least it was light stuck on rather than off so no early flower initiation!!! Got everything reset and all looks good so far. Will be using programmable timers for flower, JIC!!! Funny thing I noted while making the time lapse, the plants still "Went to sleep" at the time they should...even with the lights on and woke up when they should! Was quite interesting to see! Apart from that, just LST and plucking some bud covering leaves. Dropping the SCROG screen tonight and this will most likely be the last week of veg. As EC was dropping slightly by end of last week, have upped the EC by 0.1 Happy Growing all!!! 💪

Week four was definitely the week when the plants started to really grow bigger, I started some LST at my way cause even if I check thousands of videos I end it up doing what I thought was better for my plants, I perhaps was a bit late so it wasn’t stretching as I thought it would have, maybe I shouldn’t have wait this long, but again first time learning a lots.. I let the plant grow with LST only in week 4 in week 5 I introduced a scrog I made myself cause I thought that I couldn’t keep doing lst because I started too late
