Great week. I simply keep watering more. I'm going to start with the juices and more kelp meal sprinkles next week. They're getting taller by the day and no sign of being waterlogged and no runoff either. Green, smelly, in pre-flowering or transition state, companion plants taking off also. Haven't spotted any males or male pollen sacks in the grow area after the removal of 6 identified males. No pollination from my grow, but the environment is wild for pollen around here--i get seeds every year--even if it's just 8 seeds from a whole pound of harvest--a bee lands on the flowers in mid-october and it's like 50/50 seed or not in that location--just saying that it's part of growing outdoors without a net.

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 6 Veg - January 16/21 to 22/21 ***** Week 7 will be their last week being able to take them out of the tent😟 SCROG netting going in on the weekend ahead. Not really a lot to report this week as the girls are doing well and I am just wanting their side branches to grow longer to help filling in the canopy anyway. Performed more LST this week and bending over the branches daily. Didn’t do any HST this week, will once the net is in and I have a better visual of how the branches need to bend. They have come a long ways over the last 2 weeks when you look back at pictures. They have filled out with more side branching and other than battling a little purple striping on the main stems they seem pretty happy. Leaf colour is good and should be in good shape for the flip soon. Will go through all of week 8 before flipping so hopefully week 9 will be transition week and week 10 the start of flower.......have to get through next week first though😀👍 Switching over to tap water again. I have been struggling with calcium and magnesium deficiencies on all grows for the last year. I can’t seem to get the right amount added back to the RO water I use in all feedings. So running with straight water again now. Ppm coming out is 325 so I will work with that. Going to explore my own RO system in the house rather than bottled water, a system that adds back calcium, magnesium, and iron. It’s been flowing okay for the first week and will continue on for now. Using RO water I have been feeding full strength on the nutrients and have been working on backing them down a bit to compensate for the starting point of 325 now. They have continued to be fed once a week roughly and supplemented with calmag and microbes. Little more detail....... Jan 16/21, Day 36 Veg - 3L each of full line at full strength in RO water - 1150ppm and 5.8pH given to the girls - didn’t add any other nutes other than IPP line. Jan 17/21, Day 37 Veg - dry out day - pulled down all the girls again tonight to train them outwards. - Jan 18/21, Day 38 Veg - 3L for each girl today with tap water and CalMag @ 1ml, Microbes @ 2ml, Nature’s Candy @ 1.5ml - 700ppm and 5.7pH is what that works out to. - have to use a considerable amount of pH down to adjust the tap water, over 6ml in 16L Jan 19/21, Day 39 Veg - measured the girls today, GSCHB Is 12” tall. They were topped already😀 - dry out day for the girls. - Jan 20/21, Day 40 Veg - 2.5L each with plain tap water - 295ppm and 5.8pH. - all the girls are looking big and bushy today.......they are ready for flip soon. Jan 21/21, Day 41 Veg - dry out day for the girls. Jan 22/21, Day 42 Veg - pulled all the girls down again......repeating the same LST each day manually rather than tying down for now. - this should be water day but leaving for today as I am going to lolipop the lower branches and a heavier leaf stripping tomorrow. - will feed tomorrow as they will benefit more. Very solid week ETS......the girls are taking off and expect to see lots of leaves popping out over the next couple of weeks😀👍 Work on the side branching to come up higher closer to the tops next week.......continue tap water and give a feed with Epsom Salts new week

Originally the right plant was stunted and I was concerned that topping it would stress it too much. As such, the left plant was topped during early veg but the right plant was never topped and it shows. The main cola on the right plant gets more ppfd (around 1000) than the left plant so I’ve been bending it down once or twice a day so that maybe the left canopy can catch up. Are there any other techniques I can do to my plant (2nd week of flower) to allow the canopies for each plant to be equal? Last week I did a very light dose of bloom and they responded very well. I will continue to supplement lightly until the sohum soil prepackaged nutrients run out. I would imagine it will be any week now that it’s depleted? I am very happy with the grow so far since it’s my first ever real attempt. Other than the right plant getting shocked from the living soul or overwatering the grow has been going great! I can see baby buds and pistils forming! 😀 So excited for the day I can open the tent and get bombarded by the smell of the buds.

This is first week. i cover those plant with plastic glass. because from my expierence. from the old day. there are many enermy of your plant such mouse or many insect can get in your grow tent. so it's bad thing for me when the rat in my house come and ate all of my little plant when it age 1 weeks. so it should not happen again. before your plant strong. this state of plant is weakest of your plant. this time must very be careful.

Heatwave gone, sun still around. Rocky (Purple#1) is a killer! Growing 16 new tops and adopted a nice symmetry after just 2 rounds of topping. So much stretch after the first couple days of diffused light outdoors! Nodes are at least 5cm apart. Most new tops are coming from one node further below the cut. I’ll probably leave it at that and focus on getting them all equally tall and spread outwards. Excuse my enthusiasm - first time growing photos outdoors. This hits different! Prince (Purple#1) was super slow to redistribute auxin after LST but it’s finally getting to the right places. Lamin J (Casamance Sativa) is stretching so hard, main stem is LTD’d halfway around the pot. By the time I can flip them this one gonna be a basket! Lamin HC (Casamance Sativa) stretched a whole lot too and grew huge leaves. Little less busy pushing new tops compared to Rocky. Gonna have to top this one again soon to get to at least 8. Jimi (Purple#1) about tripled in size after going outdoors but hardly developed any new nodes. Got too lanky and I chopped it in half. Little clone now trying to make it on the window sill.

Added Exhale c02 and top dressed in each pot with 1 tablespoon per gallon of growing medium my pots are 3.6. I added 3 tablespoons. It is my hopes that with adding the slow release dry amendments and once the c02 bag sarts growing my plants will finally grow. They are short but have 4 nodes at day 21. What is an exhale c02 bag? “The ExHale bag is a patented strain of mycelium that produces an abundance of CO2 without fruiting. This means that when our bag is activated, the mycelium grows, eating the substrate it comes with, giving off heaps of CO2 straight into your garden, and it does all this for 6 months - guaranteed!” At day 25 I am not impressed with the size of these girls? Hope they hit a growth spurt soon? Their internodes are stacked very nicely. At day 28 growth is very slow. Practically none existent since my top dressing at day 23. 2 plants have received a very minimal nutrient burn. As I do not have a soil ph tester? I will be watering with a ph of 6.0 rather than 6.5, hopefully that helps. ONWARD!

Day 50 since seed touched soil. From now on all is in stable position. Joe always will be in left corner, under fan, he was lowest, so it was smart to put him under. Plants dont grow well next to fan. 5 liters went in, want good run off and saturation. Later today will install second level of scrog. Reposition all shoots, some are lost, i almost regret instaling scrog, lost control of even height a bit, but canopy is very dense, branches went fatter during that week, i am happy . Mars TSL2000 is on 80% will increase to 90% at the end of this week. Day 53. Second level of scrog almost eaten, will have to make third, plus heavy clearing awaits next week ... Day 54. Think tomorrow is watering day. Girls need good clearing, bottom canopy been canibalised heavily, lack off air shows a lot. Will do third level of scrog together with watering. Day 55. Watered Joe, he is lowest, but looks nice. Think all deficiencies behind. Made light clearing, only bottom shoots which has 0 chance to make it, took part of LST down. Watering exposed roots - plant is occupying new lair , good sign ;) Happy Growing !!!

Very easy strain to grow. I grew the White Critical Express previous to this grow, I really liked it and wanted to try growing an Autoflower so I went for the Critical 2.0 and it was worth the grow.

Week 10 for Moby dick by fastbuds, She's finally starting to bulk up a little her flowers, but she's extremely leafy likely going to defoliate her again a bit because little worried about her main cola getting bud rot but no signs of that for now. But the weather definitely isn't helping that worry😂 I've also stopped praying her down in the mornings because of the high humidity i don't want to run into any issues. She's going to be a long living auto for sure... 14 weeks+ i reckon but maybe that will translate well to the final scale weight 😁 She was fed once this week with some FPJ, Regulator, Enzym+ & Topbooster by @aptus_portugal just to give it an extra boost!

6 weeks old C/Mass clone mum we took about 5 cuttings from her so she's going to be fat already she has lots of branches growing off her short internode spacing so tight bud formation. As you can see we have opened her up without damaging her so no recovery or time wasted. We have pulled down all the main branches with soil clamps (fantastic) Its like a rib cage pull down and secure branches then all the small what would have been not much will now become much, much more. she has 3 weeks now to transform into a tree. The 3 girl scout cookies are the little supporters put in the 3 corners their autos from weed seed express{big up dem} for the freebies, the other 3 are for different projects. so here we are.. I know now not to overwater dem because my self contained unit contains the moisture hence da reader always in the soil to give me the correct reading. ph, ppm, and temp simple get a reader😇😇

DAY 84 Watered with 1ml Grow + 4ml Bloom 💧 DAY 86 Watered with 0,5ml Grow + 3ml Bloom + enzymes 💧 I don't know, today she looks wayyyy more ready, I need to check trichomes, keep you updated!! 😘 DAY 88 Watered with BioEnhancer. 🐚 🐡 🌊 DAY 90 Watered with pH adjusted water only. 💧 Checked trichomes, they look ok, mostly cloudy, maybe some are like milk-coffee.. I asked Delicious and they said it's a Sativa, few more days and then I'm done. 😎 I wish I could invite everyone to test smoke this, it is something completely new, the aroma is more than I ever expected to come out of a cannabis plant. And being a cannabis plant is awesome already on its own! So.. I think chop chop next week! 🔪 This is an Early Version for sure! Flowering went so fast and I want to grow it again! I understand the seeds will not have as much time to ripen as with a 8 weeks flowering mum, but they can sprout. I will order more next time. And also will order the photoperiodic normal version, Caramelo, I love you! 😍 💚 🤤 💚 🤤 💚 🤤 💚 🤤 💚 🤤 💚 🤤 Have a great week!! 😘 __________________________________________________ SET UP 240W Fullspectrum LED 660nm 730nm 3500K dimmable custom exhaust fan 270/320 m³/h 3x Garden High Pro fans 5W tap water EC 0,25 - adding Calmag to EC 0,4-0,6 - adding pH minus Bloom (AHH) to pH 6,5
