Set up the tent cam to take a picture every 5 minutes during lights on so I can try and make a cool timelapse. I fed them kinda lightly and I think my EC might be a little low and thats why they're so light colored; they're hungry. I also had the light on 3 but now its on 2. Its sitting pretty high above them so I don't think it should be burning them. They show no signs of stretching however so they're definitely not getting too-little light at least.

Planta fácil de cultivar, de estatura media y producción importante de tricomas. Sus fragancias son dulces parecidas a la panela, canela, especias y un fondo un poco kush con notas a crema. Flores hermosas macizos, compactas y totalmente cubiertas de fragante resina, las tonalidades son hermosas, al moler se despliegan todos los aromas y ese tono violeta en el interior de las flores. Gracias a fastbuds una vez más por su confianza y a toda la gente que sigue el contenido. Buenos humos!

This week I Realised I'd used the wrong feed chart so I was over feeding 🙄 the leaves burnt on a few plants so I've only fed them water this week and will resume feeding from next week. There are still no pre sex pistils showing but it can't be far off now. As soon as pistils start to show I'll start feeding bloom feed. I've turned the light up to 30000lux using HLG's online calculator for converting a lux meter/app reading to PAR , my light is 3000k which with lm301H Led's works out @ 465ppfd which is about the max the plants can use in veg without supliments co2. Here's the link for anyone using quantum boards, it has different spectrum calculators. It's been really useful setting my light up so big thank you to HLG (even though I have a Geeklight) and a thank you to the GML show on YouTube for bringing it to growers attention (I love that weekly show, so much info and perspective) https://horticulturelightinggroup.com/blogs/calculators/converting-lux-to-ppfd Hope everyone's staying safe and growing 😎

The time is finally here to post the harvest. I waited till it was all done and dry before updating the dairy so will add in the dry weights next on the 2nd half of the harvest entry. I enjoyed this plant a lot, its grew well and loved how it was shorter and fatter. I wonder if it was at the dame distance from the plant if It could have done even more. Had some issues with the yellowing that was happening on the other plant in this tent. I should have treated this faster with a flush but was super reluctant and it may have hurt the yields a bit. The top best looking buds looked and smelled amazing even the lower buds where doing well not so larfy like the other plant. There was crazy strong smells with this plant, sour berries and hints of lemon, it was a best smelling plant I have grown to date. This would be a great plant to grow for beginners, cant take a lot of stress and still produces quite well and even on lower wattage leds it was good. It was not the most crystally looking plant, not like the maltezerz but still had some finger hash buildup but a small amount. I feel this plant would be a winner for a rosin press. I don't plan on growing this strain out again despite me liking a lot of qualities about it. I'm only trying to grow cbd dominate plants is the main reason. If my friends really like this I have some clones so can always give them some. Speaking of clones they are doing well outside, greened up a lot and showing signs of revegging. Took some photos of the weed hang drying on day 1 in the tent and a week later to show how much they shrink. Only some of the lower growth is larfy, will make good edibles or hash, that will be a fun project to do and may include that in my projects diary. That's about all I can think of if you have any questions just ask. m0use Disclaimers: 1. I have divided the total watts of light in half, 300w(150w) for this diary. It will accurately reflect the g/w ratio as the two plants growing in this tent are listed in two separate diaries. 2. I include any shake/trim in my gross totals as I use them to make edibles. 3. I did not follow any proper ways of listing my nutrients. Some are ml/l of total solution watered, others ml/l of total medium and some are just the total amounts I added, not as a ratio.

I converted the cents into dollar amounts beforehand to avoid dividing by 100. 8.2c/h = 0.082$/h 438h * 0.17c/kwh = $74.46kw * 0.15kw = $11.17 on peak 522h * 0.113c/kwh = $58.99kw *0.15kw = $8.85 mid peak 1,272h * 0.082c/kwh = $104.30kw *0.15kw = $15.65 off peak The "h" hours and "kw" kilowatts cancel out and we are left with a value of $ dollars per peak period, add all the peak periods up and you get your total cost of running the lights in dollars. $11.17 + $8.85 + $15.65 = $35.67 for the grow light only. My light grew for 20 weeks and 4 days, or 144 days. almost 21 weeks total. $35.67 / 144d = 0.2477$/d average of about 25c a day in electricity 337.2kw for the entire grow. Using the regular calculation of grams harvested divided by watts used is not accurate to me, it does not account for all the time the lamps are on, the length of grow to the over all cost. The calculation that makes sense to me is this, harvested dry weight of usable cannabis buds/trim/keif/whatever in grams divided by total kw used. Could also combine it with grams per total single use costs “anything you used only for this grow and wont reuse in the next, or fractions of multi use items like fertilizers if they ½ full” and see how much you’re investing per gram. "kw" ÷ "g" = kw/g "$" ÷ "g" = $/g I have harvested 4.57oz or 129.6g on 337.2kw. 337.2kw ÷ 129.6g = 2.60 kw/g of usable cannabis. This is not an ideal ratio for me and looks like a lot of energy waste happened from the extended veg period. $35.67 ÷ 129.6g = 0.28c/g It cost 28c/g when comparing total electricity cost to gross yield, almost identical to the comparison of total electrical cost to the number of days in the grow 25c/day. Neat! legend, kwh = kilowatt per hour kw = kilowatt w = watt h = hour c = cents $ = dollars d = day LED= Light Emitting Diode

​🌿 VEG WEEK 4: AK-47 XL | Divine Seeds ​🌱 VEGETATIVE PROGRESS ​Moving through Week 4 and the response to the topping has been phenomenal. The growth hormone distribution has shifted completely, turning this AK-47 XL into a beautifully thick, bushy canopy with multiple strong shoots pushing up. ​Looking at the lower structure, the main stem is getting incredibly thick, acting like a solid tree trunk already. The node spacing remains tight, and the plant is developing a very dense structure from the top-down view. The fan leaves are wide, lush, and a healthy dark green, showing that she’s soaking up the light and converting it efficiently into rapid growth. No shock, no slowing down—just pure vegetative vigor. 📈 ​💧 NUTRIENT FEEDING & WATERING ​She is processing the current feeding well, supporting both the thick stem development and the new branch expansion. ​Current Feeding Schedule (per Liter): ​Root-Juice: 2.0 ml/l ​Acti-Vera: 1.0 ml/l ​Calmag: 0.5 ml/l ​Parameters: ​pH: 6.5 ​Relative Humidity (RH): 69% ​Temperature: 23°C ​VPD: 0.88 kPa (Perfect spot!) ​CO2: 716 ppm ​💭 GROWER'S NOTE ​The canopy is filling out perfectly after the top. We now have a great multi-topped baseline, and the side branches are catching up fast to create an even profile. Stem thickness is 10/10 for Veg Week 3, which is exactly the robust foundation needed for the heavy AK-47 XL yields later on. With a stable VPD of 0.88 kPa, environmental stress is at an absolute minimum. Ready to explode! 🚀

Continued feeding plant with each watering of 2 litres every 3/4 days. The flowers are fattening up nicely, into some bigish colas, meaning harvest isn't too far away. Removed some dieing leaves from bottom of the plant. Almost time to stop feeding and start the flushing process.

Ein regelrechter Höhenrausch prägt das Bild zum Start der vierten Blütewoche bei dem Junky 99 Projekt von Brothers Grimm Seeds. Der Stretch ist derart extrem ausgefallen, dass die beiden Damen kurz davor sind, die Decke des Setups endgültig zu sprengen – ein bisschen kompakter hätten sie im Nachhinein betrachtet gerne bleiben dürfen. Ob dieser massive Wachstumsschub nun rein an der Genetik liegt oder durch das für mich noch neue Advanced Nutrients System befeuert wurde, lässt sich schwer sagen, da ich die Feinjustierung des neuen Düngers für mich persönlich erst noch perfekt abstimmen muss. Eigentlich wurden die Pflanzen mit einer absolut soliden und normalen Höhe in die Blüte geschickt, doch die jetzige Dynamik war kaum vorhersehbar. Genau deshalb stand direkt zu Wochenbeginn das überfällige Lollipoping auf dem Programm, bei dem angesichts der enormen Gesamthöhe nicht zimperlich vorgegangen wurde: Untenherum wurde radikal aufgeräumt und kräftig weggeschnitten, was für die Durchlüftung und Lichtverteilung auch bitter nötig war. Trotz des extremen Höhenflugs stehen beide Pflanzen makellos im Saft; die Blütenbildung schreitet rasant voran und überall formieren sich vitale, vielversprechende Bud-Cluster, die schon jetzt einen exzellenten Eindruck hinterlassen.

1/12/26 4:18AM MONDAY.....💪💪💪💪👌 1/12 CANNAKAN DAY MEDICINAL 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! 🌱💪😂

The seeds were planted three days after the paper towel and the first one grew out of soil the same day.That seed was planted with its first leaves(cotyledons).

Day 36-42 Ladies gettting bigger. Putting in net for LST Btw Day 42 already Flower Day 4! So the pics near the end are start of flower :) In my opinion the stretch is not that much, so keep them ladies longer in veg. Looking back i d say veg another 10 days maybe and then get them into flower. Mine was too early
