An extremely vigorous girl performing well to this point in hydro. I did a bucket change out week two of grow and honestly hasn't needed any additional nutrients other than topping with fresh RO water w/cal-mag. I topped her beginning of week 4 and now as of this writing gave her a defoliation at base of plant for aeration and applied a bit of LST. We'll continue to monitor ph daily to minimize potential swings. Midweek 4 update - Top off about 3/4 gallon of ph'd (5.5) RO water w/nutrients and cal-mag at a range of 625-630 ppm. TKO just continues to impress me a hydro newbie, but impressed non-the-less. There is approximately 24" of vertical grow space remaining, so the SCROG net is going up, which means the other struggling 5 gal hydro bucket with Ethos Punchberry Cookies will have to move to the 3x3 tent. I'll move two 3 gal Gelato strains into the 2x4 AC Infinity along with the TKO and prepare for final week or two of veg before flipping to 12/12.

I started getting new growth from the tops of my colas. I thought this might of been down to raising the light up 10cm but it might of been down to high light intensity so I also moved one abit further away from the other to try and help. The pictures in the dark and videos was around 4minutes before the lights came on as all my photos are over exposed. Next to this plant I have an experiment with pink kush and zombie kush using the light given of from this grow.

1/12 4:14AM MONDAY!!!!!!!! CBG IS GOOD!1 LOWERD THE WATTAGE, EFFICIENCY IS GOOD. GREAT WHITE MYCO HAS INCREASED UPTAKE AND AND!!!! PHOTOSYNTHESIS EFFICIENCY ......FUCKING AWESOME 💪💪💪💪 1/12 4:47AM I asked GROK: are samsung leds on my mars hydro lights seem more efficient than the PPFD meter says, I lowered the lights again by a few watts? 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. 🥊🍌👨‍🔬🚨🌞 1/13/26 7:47AM BRUTAL WEEK FOR THE MOP AND BUCKET GUYS AT MUDRUROS COMPOUND 1/13, 11:22 AM banana purple punch auto RF three is doing really great. I haven’t really needed to do anything. I decided not to top. I didn’t want to do anything except light stress training. I think she’s gonna turn out just great. Her stock is one of the thickest. She’s just perfect.😍😍😍

Growing like a weed. Light burn mid veg, due to ph meter broken. Quickly recovered after flush. No issues since. Day 14, lowering nitrogen tomorrow. Slowly raising her ph a wee bit, she doesn’t seem to mind. 7 out of 8 seem to be on the same pace, one is a little slower. All plants, aside from color, look the same genetically. Rare to have a bag of seeds with the exact same plants. Good job Grower’s Choice. Still no pollen sacs on sprayed branches.

04/11 - Both plants are coming along accordingly on time - As stated previously I got careless with the PH and they suffered a harsh PH burn - Since then they have been flushed and nutes in coco stripped - Began introducing nute in micro-dosing stages.

This week did not go too well. The plants started being more and more droopy and barely grew, which you can clearly see in the time-lapse. I initially thought they were sitting in coco that was too wet, but drying it out did not help their case. I had already wanted to transplant them at this stage, but didn't have the right pot size available yet due to a late delivery. Then, at day 13 from planting the seeds, I received the pots and immediately went on to transplant them into wet buffered coco in 1 liter pots. They instantly recovered and have been doing great ever since as you can see in the last picture. Starting from the transplant, I have been feeding them with 0.5-0.7 EC water, a bit more than half of that made up of calmag, the rest coco A+B and rhizotonic. One is showing a slight calcium deficiency, weirdly enough. Especially as the coco was buffered in a 1.2 EC calmag solution for several days before use. Will keep an eye on this and might give some extra calcium as a mono nutrient. For now, next week looks promising. This update is a little late, so I can tell you that by next week's update they will look much better.

Bad Guy got hit with a heavy salt buildup, measuring around 1500ppm in the runoff. Planning to flush it during the next two feedings and see how it responds. Keeping fingers crossed for a swift recovery! 🌿🤞

Monday’s Blue, it looks like she’s flowering but I am not sure but I will find out very soon with this coming week, the days are getting hotter and now an hour longer. I almost lost hope, the leaves were drying out, but with time knowledge is acquired and look at her now, she does show signs of going through trauma but now she healed ad growing like the rest.

The Holidays caused a little headache this past week. Was a few hours late on water schedule due to holiday commitments. Found the middle plant had sucked all the water out and went into underwater stage. A few of the giant fan leaves took a hit, but not too bad. Didn't change anything other than water schedule to every day now and the leaves had no further damage/discoloration. All leaves still praying and doing good. Trichromes starting to pick up on all the plants now. Had a situation in my other tent with a plant that shouldn't have been saved, that i saved, and seems to have slightly hermied and I didn't catch it. Not terrible, as out of a 6 oz plant, I found 42 seeds. Hoping that tent doesn't effect this room, but it's possible it has. Just gonna ride it out now and see how it goes.

Week 4 begins for Mandarin dreams and Divine storm. Both ladies are looking happy and I increased their feed by 1 liter each. Thank you Mars-Hydro for the TSW2000 light, very happy with the light performance so far. Thanks for stopping by growfessors 👽 tune in next week for another episode of growfessor theatre!

Day 50 - Started week 8 today and things are looking good. I’m still a rookie at all this but it’s looking like this girl might be a beast, at least for me. Gave her a feeding of the foxfarm trio today and did a little leaf tucking. Just waiting for her to start putting on some weight. Day 51 - She’s looking really good and stretched another half an inch. Gave her some more water today since she’s drinking like a fish. Just gonna continue watching her grow and fatten. Day 52 - What can I say?!! This girl is gorgeous and starting to fill in and stretches another 1.5” overnight. She’s slowly starting to fill in and lovin’ it. Love watching the day to day changes. Gave her just another feeding of water and will give her the foxfarm trio feeding tomorrow. Day 53 - Nothing too major to report, looks like she stopped stretching and is starting to fill out and looking good. Day 54 - All is looking good and really starting to fill in now and getting a bit frostier everyday. Two days in a row of no more stretching so hopefully she’ll really start filling in more. Day 55 - Things are taking off with this girl. She’s starting to fill in nicely. Gave her straight water and in the next couple days, I will start week 9’s schedule for the foxfarm trio. She starting to frost up a bit and loving it. Day 56 - Last of week 8 and rolling into week 9 strong. All is looking good and gave her the first of two week 9 feedings from the foxfarm trio. Starting to get a bit frosty and lovin’ it.

Hey there, fellow plant enthusiasts! It’s time for another exciting update on our magnificent P.C.R.s as they journey through their second week of flowering. Buckle up, because things are getting wild in the grow room! Our P.C.R.s are on a growth spurt like no other! They're reaching for the stars and filling up the entire room with their lush foliage and budding flowers. It's like a jungle in here, and I’m loving every minute of it! The energy in the room is electric, and you can practically feel the excitement buzzing in the air. With all this growth, our grow room is bursting at the seams! These plants are not messing around—they’re taking up every inch of space and demanding attention. It's like they're saying, "Look at us, we're the stars of the show!" And let me tell you, they're stealing the spotlight with their beauty and vigor. As we approach day 21, the anticipation for defoliation is real. But our P.C.R.s have other plans—they're playing hard to get! Despite their reluctance, I’m keeping a close eye on them and patiently waiting for the perfect moment to give them a little trim. After all, a little pruning goes a long way in ensuring optimal light penetration and airflow, leading to healthier and happier plants. Defoliation is like a mini makeover for our plants—it removes excess foliage, allowing more light to reach the lower buds and promoting better airflow throughout the canopy. This not only improves bud development but also reduces the risk of mold and pests. It's like giving our P.C.R.s a spa day—they come out looking refreshed and rejuvenated! Week 2 of flowering has been nothing short of exhilarating! Our P.C.R.s are growing like champs, filling the room with their vibrant energy and undeniable charm. While we wait for the perfect defoliation moment, we'll continue to shower them with love and attention, nurturing them every step of the way. Shout Outs A big shout out to @aptusholland for their incredible products that keep our plants thriving.

Cosecha

Fed and defoliated to start week 7. The plant looks good, the buds are on point, frosty, sticky and look as expected at this stage of the grow.

We are entering the finish line, 1 more weeks of flushing and harvest 🔥😎 N 80 P 113 K 224 Ca 50 Mg 95 S 100 Fe 1,2 👌

Day 36. Big week . New light was added and rhythm changed to 12/12. Pot was top uped with 3 handfulls of BioBizz Worm Castings. 1.5 g of Biosys and 1.5 g of Great White were added too. After training she got 2l of water, slowest drinker at the moment. Girl got small defoliation, when you bent main top, one fan leaf is always staying in everyone's way, so he had to go. Think to do big clearing on day 14-18 of flower. Got first wave of LST, main top was lowered, couple leaves and one shoot were repositioned and secured too.. Genererally stem is thick, needed two places to tie, to make any movement, side shoots are developing evenly too, all thanks to : TS1000 by Mars Hydro, great light, did perfect job during veg period, now i added one more for better coverage of long tent. Think in tent 1x1m i could manage to flower all 3 without any ad ons .... Great small light for amazing price. Day 40. Girl develops nice and even, good colour and i am happy with her. Day 42. New training day, first time took so many away, girl lost 10-15 leaves, most were huge, no bottom clearing still. 2.5 liters of 6.3 water went in. Happy Growing !!!
