11/21/24 Short facts: - Watered: 1 x 1.0L, 1 x 1.5L, 1 x 1.5L, 1 x 1.75L — 5.75L - VPD @ 1.4 — raised by 0.1 - Light @ 80% ~700 to 1050 PPFD - BioBizz Bio-Bloom increased to 3ml/L - BioBizz Bio-Grow increased to 3ml/L - Getting colder! At night between 18 to 19°C --------------------------------------------------------------------------------- There isn’t much to report this week. She’s doing fine, but she might need a little more CalMag and nitrogen. So I’m giving her some extra CalMag and a small amount of bonemeal. Since the weather is getting quite cold for the region - and we’ve already had a bit of snow - the cellar where my grow tent is set up is cooling down, with nighttime temperatures dropping to 18–19°C. Therefore, I’ve ordered some heat mats, which should arrive tomorrow. I’m aiming to stabilize the root temperature at around 22°C consistently, so the nights won’t be too cold anymore. I’ll go into more detail in next week’s update.

Week 10. A bit behind the schedule considering I switched to 12/12 after week 1 but I don't rush. It was just an experiment to see what;s gonna happen when I switch so early.. Not much I guess :)) The left plant was like a week behind for the first part of the grow and now doing way better then the other one. Not sure what affected the one on the right if it's just genetics or something else but she is little bit slower now. It makes me feel like a light leak so I tightened up the tent and we will see. Fingers crossed it looks very promissing. I also have to leave for 5 days so I have to setup autowatering and hope it's not gonna die till I come back :) See you next week

Praying my girls are not all in different stages of dying 😭More to follow... 1/9/21 These girls were finally dry enough to water I weighed each post before and after watering. I am going to try weighing the pots and water when the weight is about half as dry.as I normally do. So Maybe I should water @ 3lbs heavier... somewhere between 8-9lbs 1/10 I changed the light cycle so that my "night time" is in the middle of the day for heating reason, so this morning when I woke up, after being under the lights for 18 hours I actually had growth on two plants. Gorilla Glue and my photo plant Chocoloope that is growing with the autos. They were both under the VIPARSPECTRA 2020 Pro Series P1000 LED Grow Light. The other two plants were under BLOOMSPECT Double Chips Series 1500W LED Grow Light Full Spectrum. I wish I hadn't made so many mistakes with this grow because I know there is no way to know if it is the light that made them grow better than the other two or they were just a little healthier. I don't think so because Gorilla Glue is the worst plant and she actually grew but who knows. Anyways I switched the plants around so they are under the opposite light when their day time starts and we will just have to see. PE Length 8' Height 7' Width 8.5" Dry weight 6lb 4oz Wet weight 13lb 11oz GG Length 8" Height 7" Width 8.5" Dry weight 5lb 14 oz- Wet weight 11lb NB Length 11" Height 10 " Width 10.5" Dry weight 6lb 9 oz Wet weight 12lb Choco Length " Height Width " Dry weight Wet weight 1/11/21 DAY 46S HELP if ANYONE SEES THIS .... last night I decided not to switch the plants around after all, but I did rearrange the tent because I had a plug running through door and I am still struggling to regulate the humidity and temp. I thought I still had good air circulation but apparently I did not and the plants are not happy. Gorilla Glue is not going to make it. She turned real dark green after watering her on Saturday, she had a small amount of growth Sunday but now all the leaves are laying down. I don't know if I should use Sledge hammer but after flushing a week ago letting her dry for a week and then watering Saturday I don't know if I flushed her with sledge hammer if that would finish her off or perk her back up. I weighed her and she was 4 pounds lighter than when I watered her on Saturday and still 2+ pounds lighter than when she is the driest. Some background on how I tried to kill my plants... 😭 I started this grow by watching a zillion videos with my key take away being 1-don't over water 2- don't transplant autos 3- don't feed full strength. I took it seriously, so my tiny little sprouts were put into 3 gallon pots of Fox Farm happy frog potting soil. (didn't realize this already had enough nutrients to last several weeks so I started nutrients in the 2nd week of Veg) I use Fox farm nutrients and follow their soil feeding schedule. I bought the Dirty Dozen starter kits and it did not have 2 products in that the feeding schedule but since they were not in the kit I assumed they must not be too important. They were.... Wholly Mackerel & Marine Cuisine fertilizer. I used a turkey baster to slowly drip a couple ounces of water around each plant I water just like in this picture. https://prnt.sc/wjq0gi for over a month. I didn't realize by watering like this for a month that I was making the nutrients build up just below the the root line each watering. I waited to water till the plants were very dry. Now looking back Way way to dry before watering. I am sure that is why they were not growing. I was only giving them enough to stay alive not thrive. So a little more back info Day 14 I watered the plants with plan water Day 23 after not having to water the plants for 9 days I watered them, 1/4 gallon each with week 2 schedule, with the addition of calmag+(2-0-0) @ 50% strength Day 27 they were light and needed to be watered and they had grown a little. so I gave them nutrients same as above Day 30 The plants were not quit as dry as usual but I was beginning to think I was underwatering them so I gave them 1/2 gallon of THIS IS WERE IT ALL GOES WRONG...(Actually after reviewing my grow journal just now my problems started Day 1 and was showing signs I just didn't know it and I still am not sure how to fix any of it Almost makes me think I should scrap it all and start over. These poor plants will be lucky to produce anything) Someone could seriously use my grow journal as a "everything not to do" guide. Day 35 since the plants were finally big enough to soak the pots fully. I also decided since they had used 1/2 gallon water in 3 days and they grew a ton I upped the nutrients to full strength and the calmag plus as well. This was the first time I had any runoff sadly I let the plants sit in the runoff and reabsorbed all the runoff. Day 38 Flushed each plant with with 5 gallons of tap water that had a PH of 6.4 & water temp was 62 degrees. My run off started at 4300ppm with a ph of 6.2. The PH was consistent in every plants runoff and all of them had off the chart PPMs. I brought NB down to 250ppm. Gorilla Glue and Pineapple express I brought the runoff down to 450. For some reason I decided that since my plants were probably in shock from no water and nutrients to more water and a whole lot of nutrients and I figured flushing them would reset the soil and I reasoned they would need food after not getting any from being in shock so I gave them each a half strength nutrients. I waited a full week then posted this question. Day 45 I have each plant plain water and checked the run off. The Gorilla Glue had a run off of 584ppm with a ph of 6.47 , The northern lights X had 750ppm and 6.38ph pineapple express had 1170ppm runoff so I ran a less less than an extra half gallon of water and that brought the ppm down to 706. PH was 6.3. I have a photo period that I didn't add to this dairy but has been with these plants and it is starting to show the same signs as the others they are just all in different phases of whatever I did to almost kill them. I started the next week on Friday so I will be adding pictures and a couple videos I took from today in my grow dairy tonight. I don't know what to do next.

I plan to grow the best 2 in hydro and the best 2 in soil On 40% power Big Thank you to Medicgrow for the opportunity to use the LED - I am under no pressure or obligation to promote this item , I will give you my honest opinion, and we will see the results , it’s actually a bit bigger than imagined , first test with the lux meter showed awesome spread and distribution, I have one thing that I didn’t understand, using the hangers , you need a degree in engineering to understand , I looked , I pondered, I scratched my head a little smoked a joint , still couldn’t comprehend,so I used 6 ratchets = 🤪 All of them are cuttings I took from a naughty strawberry cheesecake Ps The big green power supply there’s nothing to do with the medicgrow fold 6 ,( the power supply is in the middle )it’s from another light that I just can’t be bothered to move because I’ve got nowhere to put it Wednesday-watered the soil , topped up the pots and added 2ml of A+B hydrogrow Thursday upped the power to 60% this is the recommended setting , but I was a little cautious, I didn’t want to burn anything Probably going to cull down to 6 this week , 3 of each - throw the others - see what happens

26.12.24: I have noticed light stress on my plants. I had moved the lights further away and increased the light intensity to 70%. Unfortunately that created some issues. Namely severe palour of the leaves. To try and rectify the situation, I've dimmed the lights to about 30%, staying at the same distance, about 30 inches away. I measured the par levels, after I did this. They should a reading of anywhere between 40 and 150, at the canopy of the plants. They are all different sizes. This seems to have improved the colouring on all plants. After this evenings watering, I will monitor recovery and increase lighting intensity again slowly. I am also using the light cycle of 21/3, so the plants have many hours more light to absorb, than for example 12/12 or 18/6. 29.12.24: So I finally gave LST a shot, it's probably a bit too late, however I really want to get the most of the triploid pheno, and I went a little crazy and LST'd all plants except 2, as they're too small. I did that late last night, this afternoon I was amazed to see the plants turn their leaves back to the light source. I'm glad I overcame my fear of trying it. I'm very excited to see them adapt and progress! 😁 there are videos above with before and after of my LST process. I am pleased with the progress, considering all of my mistakes! Thanks for checking out my diary 🍃 ✌️

So am 15.05. hab ich nun das Licht umgestellt. Eigentlich wollte ich den Pflanzen noch mehr Zeit in den Töpfen geben aber die Zeit wird knapp zu meinem Sommerurlaub daher muss das ihnen reichen. In den nächsten zwei Wochen wachsen haben sie ja auch noch Zeit weiter zu wurzeln. Würde mich aber mal intressieren ob die Wurzeln in der Blüte irgendwann das Wachstum einstellen? Diese Woche haben die Pflanzen endlich mal etwas nach Dünger gerufen, dem Wunsch kam ich natürlich gerne nach. Versuch meinen VPD immer so auf 1,2 zu halten, denke das ist ein guter Kompromiss zwischen den Wachstumsstadien. Generell bin ich sehr zufrieden wie mein erster Homegrow so verläuft und das die Pflanzen so gesund sind. Macht aufjedenfall mortz den Spaß und hab auch schon sehr viel dazu gelernt.

11/10 12AM MONDAY 11/11 626AM how about a WWII German Hero Grow? 11/11 255PM great news neck bleeding so no plant work today...how am I not dead yet??, this is bullshit. 11/12 440AM THE DEMON REVEALED ITS SELF TONIGHT. BIG MISTAKE!!!! GREAT NIGHT FOR ME.....DARK DEVIL AUTO IS IN MY LUNGS AND BLOOD RIGHT NOW AND ITS ALL HAPPY!!! GOOD LUCK FOR ME, DEMON HUNTERS PARADISE!!! 11/12 501AM. DDA is PERFECT RIGHT OFF THE TREE. SOMETHING AUTOFLOWERS ARE GREAT AT IS SMOKING WITHOUT HAVING TO CURE AND DRY. ITS 100 TIMES BETTER WHEN I DO, BUT ITS GOOD FOR MEDICAL USE AND NOT OVERLY STRONG WITH ALL THE FLAVORS OF BERRY AND VANILLA!!!!!

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! 🌱💪😂

Last Sunday I increased the nutes so that the ppm was on the higher level (600-625) as the feeding schedule showed. Dec 9th I started to see some lime green (video) leaves on new growth. The ppm would go up mostly & down slightly, but the lime green spread & eventually turned yellow (last pic from today). I did a water change the other day & lowered the ppm/nutes to around 575-580 range. I've been reading around that this might be a sulfur deficiency? Some suggested adding Cal-mag. Today I added 2 ml more of Cal-mag & snipped some of the darker fan leaves that had some damage. I ordered epsom salt, waiting for it to arrive (tomorrow). Any other suggestions/diagnoses are welcomed! 😊
