This is my second Big Bud grow but my first outdoor grow. The buds aren't as dense and the indoor with my CO2 bag. The bud is still very potent though.

This week we should really see these colas blow up and start stacking really strong. The mixer of 7 hours of sun and 17 hours under my LEDs has really helped my girls grow strong. Nothing compares to good old Mother Nature.

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! 🌱💪😂

Start Woche 3 Blüte Diese Woche darf sie noch ungestört wachsen. Ende der Woche wird sie dann für die restliche Blüte fertig gemacht. Heute gab's zudem wieder 4l Wasser mit 20ml/l Green Bull. Hier und da hat sie ein paar kleine Stellen (Schätze die Gründüngung + BioBloom gleichzeitig war etwas zu viel). Hält sich jedoch in Grenzen 👌🍀 Ansonsten sieht es eigtl. gut aus, bis auf das sie absolut nicht gleichmäßig wachsen will😉😉 Werte sind noch immer 1,1kpa Vpd bei ca. 800ppfd. Licht wird noch bis auf ca. 1000ppfd hochgedreht. Tag 18 Blüte Ab heute bekommt die gute 1000ppfd Licht, Vpd bleibt aktuell bei 1,1 - 1,2kpa. Ansonsten schaut es vielversprechend aus 🍒🍀

Week 9 marks a turning point for the grow. The main plants are deep into flower now, with dense buds that glisten under the HPS light. Their smell is intoxicating, filling the room with the rich, sweet aroma that hints at the potency to come. Even the late bloomer has stepped up its game. While it’s still behind the others, it’s finally entering full flower, its smaller buds beginning to form. It’s got a unique charm, and I can’t help but root for it—sometimes the underdog ends up stealing the show. The grow room feels like it’s nearing its peak. The plants are massive now, with thick branches bending under the weight of their buds. Every day brings new changes, and I can see the finish line getting closer. The hard work is paying off, and I can’t wait to see how these beauties turn out in the final weeks.

little clone lollipops still partying. Just hand watering ever couple days, or throwing one of the drip rings into the pot once in a while. I also am rotating the pot a 1/4 turn when I remember. Will probably move this out from under the shade this week cause I think they've gotten used to the flower lights and will bud soon.

Of the four plants Barney's LSD Auto is the most vivacious, with the Strawberry Cheesecake and Onyx only a week or so behind. The Northern Lights Auto is very disappointing with absolutely no branching...and some discolouration in the leaves. If she doesn't show some branching after topping, I'm going to pull her and grow a different plant. Real estate in my grow room is in high demand and I won't waste it on a dud plant :D

Through out the week she received a foliar spray of Epsom Salt to prevent any Mg issues the others had in the tent. She is the shortest and smallest of the bunch but her foliage is the most vibrant. Very healthy and strong stems forming.

They are stretching a little more than i expected.. got some light bleaching, try to dim the lights a little since i can't get the lamp any higher.. Defoliate at day 21 again. At day 21 i flush with 3L 1.0EC, 5.5pH and let it dry out. Pheno 4 got some beautiful pink/reddish coloring in the leafs already. (Alot of new white flowering hairs that are stacking up more than other phenos) Let's hope they'll turn out great. The smell is coming true, some have a little sugar leaf. Waiting game is on

I don’t think I ever had white powdery mildew and I was just noid of every little dust particle that came around. All good. I’m now battling high temps as we don’t have central air and it’s mid 90s outside. Most likely about to buy an ac unit. LST seemed to go ok but we shall see. Overall very pleased w my results so far.

They are developing well and the smelling started to be a bit strong with gas terpenes from both strains. I'll keep following the EC and their development to ensure they won't have any blocker. Day 42 - 15/05/2025 🌞 ~900ppfd ⏫🌡️~28°C 💧~49% 📏 40cm distância 3 day later the soil got dry, what it seems the watering cadence based on the pot size. They are going very well. After talk with some friends and reviewing the plant status, I decided to keep follow the nutrient schedule and keep looking at them. Mango Cream and Strawberry Cola 1 stopped stretching and should started the bulking phase, that's why the smelling is so strong. On Strawberry Cola 1, I just remove some leafs that were covering the other branches. I, literally, removed 5 leafs. Watered with 3L of RO water with 4ml of Athena Bloom B + 4ml of Athena Bloom A + 4ml of Athena CaMg. EC 1.9 EC Run Off 5.8 PH 6.0 On Mango Cream, I did some defoliation removing the big leafs on the bottom, that was nothing receiving light and probably consuming plant's energy. Then, they can concentrate on the top canopy. Watered with 3L of RO water with 4ml of Athena Bloom B + 4ml of Athena Bloom A + 4ml of Athena CaMg. EC 1.9 EC Run Off 6.1 PH 6.0 As Strawberry Cola 2 is one week later than the others. So, it seems going to finish the stretching bloom phase. As Mango Cream, I did some defoliation removing the big leafs on the bottom, also some ones in the middle, that wasn't receiving light and ambushing the middle overlapping the middle nodes. Then, they can concentrate on the top canopy. Watered with 3L of RO water with 4ml of Athena Bloom B + 4ml of Athena Bloom A + 4ml of Athena CaMg. EC 1.9 EC Run Off 5.9 PH 6.0 The defoliation on them also was done to improve the air circulation because my tent increased 1,5-2,0C. degrees with the season changing. Hopefully it can help to reduce a bit. As the previous EC on them were between 5.1 and 6.1, it means that they are ok, consuming the nutrients and not blocked by high EC. Happy news!! Day 45 - 18/05/2025 🌞 ~900ppfd 🌡️~26°C 💧~49% 📏 ⏫45cm distância 3 day later the soil got dry and they are going very well. I'm keeping the strategy this week in order to levelling the EC on them. Seen they sucked a bit their development and some burns started to show on the leaf points, I decided to flush them a bit to correct the EC and continue the nutrients schedule correct. I flushed them with 6L of RO water with PH corrected, each one. They reduced the EC to 2.0~3.4 and I added another schedule nutrients solution. All water schedule below is after the flush. Mango Cream I watered with 1L of RO water with 2ml of Athena Bloom B + 2ml of Athena Bloom A + 2ml de Athena CaMg + 2ml of Athena PK. PH 6.0 EC 1.9 EC Run Off 5.3 Strawberry Cola 1 I watered with 1L of RO water with 2ml of Athena Bloom B + 2ml of Athena Bloom A + 2ml de Athena CaMg + 2ml of Athena PK PH 6.0 EC 1.9 EC Run Off 4.9 Strawberry Cola 2 I watered with 1L of RO water with 2ml of Athena Bloom B + 2ml of Athena Bloom A + 2ml de Athena CaMg + 2ml of Athena PK PH 6.0 EC 1.9 EC Run Off 4.5 I also did some defoliation on Strawberry Cola 2 to improve that light penetration and air circulation. Day 48 - 21/05/2025 They definitely are in the bulk phase. The smell is crazy. My flush strategy was successful and they are eating like a monster now and without any bad signals. Happy with the correction results. I also increased the watering volume. Mango Cream I watered with 3,5L of RO water with 5ml of Athena Bloom B + 5ml of Athena Bloom A + 5ml de Athena CaMg + 4ml of Athena PK + 5ml of Athena Cleanse. PH 6.0 EC 2.0 EC Run Off 2.8 Strawberry Cola 1 I watered with 3,5L of RO water with 5ml of Athena Bloom B + 5ml of Athena Bloom A + 5ml de Athena CaMg + 4ml of Athena PK + 5ml of Athena Cleanse. PH 6.0 EC 2.0 EC Run Off 2.7 Strawberry Cola 2 I watered with 3,5L of RO water with 5ml of Athena Bloom B + 5ml of Athena Bloom A + 5ml de Athena CaMg + 4ml of Athena PK + 5ml of Athena Cleanse. PH 6.0 EC 2.0 EC Run Off 2.8 I did a slightly defoliation on the bottom leafs to improve air circulation. This week is working in progress and should be update asap due the plants development. Cheers!🍁🔥
