Last week for these ladies. Kept the soil moisture levels very low leading up and did a final heavy de leaf of pretty much anything that doesn’t have trichomes growing on it and will be shutting the lights and turning the heat off for the last 48 hours. Keeping a lot of the sweet leaf on to keep the moisture throughout drying and will do a dry trim. Will be aiming to have a long slow drying period (12-15 days hanging) before I jar them up for curing. Won’t be adding many quality pictures this week since half the time they’re in the dark but will post harvest pictures as they come down :)

Bin sehr glĂŒcklich ĂŒber das Resultat. Die Sorte ist mir richtig gut gelungen, nicht nur vom ertrag auch die Kompaktheit der Buds. Ich glaube mein nĂ€chstes Projekt wird Runtz Muffin sein. :))

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 đŸ’ȘđŸ’ȘđŸ’ȘđŸ’Ș 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 ÎŒmol/J** efficacy, pushing the whole fixture to around **2.85–2.9 ÎŒmol/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+ ÎŒmol/mÂČ/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 ÎŒmol/mÂČ/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. đŸ„ŠđŸŒđŸ‘šâ€đŸ”ŹđŸššđŸŒž 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.😍😍😍

Una cepa bastante fĂĄcil de cultivar,yo al preparar un sĂșper soil a base de guano,ĂĄcidos humicos,bacterias,mi suero de lactobacillus casero,algas marinas y humus,tan solo regue con agua por lo que no tengo mucho trabajo en ese sentido,ademas tampoco le aplique ninguna tĂ©cnica de entrenamiento cosa que me gustarĂ­a hacer si tengo oprtunidad de volver a cultivar esta cepa, sin embargo vi que empezĂł la floraciĂłn siendo pequeña de tamaño,tĂ©rmino dando una excelente porra central y algunos cogollos bajeros con los que me fui haciendo algunas infusiones con leche entera y tambiĂ©n con aceite de oliva para no tener que recurrir al mercado negro y poder asi añadir mis canabinoides a mi sistema para poder mejorar mi lumbalgia y descansar mejor. El aroma es sencillamente exquisito,ha sido todo un placer cultivar esta cepa,lo malo es que es muy poco para mi ya que soy un usuario que necesita una buena reserva de cogollos potentes sobre todo a nivel fĂ­sico que me ayuden a lo largo del año.muchas gracias y espero que os haya gustado mi trabajo, paz compañeros Canabicos! đŸ’šâœŒïžâ€ïžđŸ’›đŸŒ±

This week I just added water and did some defoliation of leaves that were starting to show signs that their last nutrients were being used up (browning and curling up). From my last grow I know this means we are getting close to harvest - my guess is within the next week my post may be about harvesting, but I won’t rush it. I can also tell we are close as some of the stems are starting to have trouble holding the buds up. Trichomes are clearly still cloudy on both plants but in the last couple of days I’ve started to see some amber in the trichomes in different areas too. Cleaned the plants up real good with defoliation and will see where we are later this week.

Stopped feeding this week. I'm pretty sure they should be ready to chop in a week or 2. I hate looking at them with my microscope so I've gotten pretty good a judging when they are finished. I love ILGM. They always come thru with solid genetics!!

Heya Farmers. Lots of growth this week, as you can see in the video I had to do a ton of LST and defoliation! This strain had a lot of hype surrounding it in the community, but here on growth diaries most of the plants looked rather small and flowered after 2 weeks, I'm glad mine seems to be a bit bigger! she also already smells amazing, this early! I'm a little scared as shes still quite short, but if I can get dense little buds, I prefer that over stretchy airy sativas, so I suppose I should be happy, but still, so dense, so much foliage. Hope you join along to see how her flowers turn out, she's already showing some color in the tips of her flowers My Flower lights: https://marshydro.eu/products/mars-hydro-ts-1000-led-grow-light/?ref=BelgianBudtender My Veg lights: https://marshydro.eu/products/mars-hydro-ts-600-led-grow-light/?ref=BelgianBudtender Coupon code BelgianBudtender for 3% off

Hey Growers, end of week 7 from seed :) This is plant #2 Its a female Took a while for me to reveal its gender. She is looking healthy and is growing fast. Did some trimming Slowing increasing nutrients, I am Currently feeding every three days 1 gallon of water with 1/2 of the recommended feeding schedule given from the manufacturer. Will keep you guys posted with more, see you next week 😊

Day 86, 5th of December 2020: Absolute adorable. She is the most calmed from the Original Sensible Seeds family I am currently growing.... No problem no crazyness she just keeps going.... Looking pretty like this plant! Not much to say we are here at beggining of the 5th week :) The lamp is now on 11 hours and off 13 hours. Every week 15 minutes was taken off and after 4 weeks here we go. Strated 12/12 and now 13/11 wanted try to imitate the nature as the light days are getting shorter. Fertilization has changed no more epsom salt from this week and I will stop giving nitrogen as well from next week.

This week the plant finally gets the tent to itself and I began training for a wider canopy , poor girl looks tortured lol in this week I notice a mutation on one of the branches fasciation which I show in the video I’m unsure as what to do because in the week because I want to switch the plant very soon to flower and don’t want to waste a branch but I kinda wanted to see what the buds would look like if I left i ultimately decided to chop it
