SpliffyRand Day 0 - Germination After trying out Mephisto in the last run, their genetics already got me hooked. Out of the three different strains I grew, I liked 505 Headbanger the most. Good yield, good effect and a beautiful lime green appearance. This round is going to be hands off again, following more or less the same strategy as before. Things I changed: -First time using Plagron instead of BioBizz soil -3 plants instead of 4 -Only one strain - 505 Headbanger -Using Mycotrex and Bactrex when germinating -Starting germinating with Farmer Hat Beards mud pie method

SpliffyRand Day 1 - There is life After 4 days of germinating, all Headbangers popped. I will keep the humidity domes on them until the seedlings are getting too big. For extra humidty I added a wet towel to the tent. Quick Stats: -SANlight Evo 3-80 @ 25%, 40cm distance -humidity domes -23,3 °C -Day 1 is 28.12.25

SpliffyRand Day 8 – Second pair of leaves After a few days, I removed the humidity domes and transitioned into a light, regular watering schedule. The seedlings are currently receiving approximately 330 ml of fresh water every two to three days, supplemented with 1 ml/L BioBizz BioGrow and 0.15 g/L Epsom salt. In addition, two BioTabs per pot have already been applied so I dont run into deficiencies again. On day 8, the SANlight EVO was increased to 30 % output, which corresponds to approximately 18 DLI in my setup, calculated by using SANlights documentation and tests (https://www.sanlight.com/news/par-test-und-ppfd-plots-der-sanlight-evo-serie/) Quick Stats: -Day 8 / 84 -SANlight EVO 3-80 @ 30 %, 40 cm distance -Temperature: 23.3 °C -Relative Humidity: 35 % -VPD: ~1.9 kPa -DLI: ~18 ####################LED settings#################### Days 1-7 | Seedling 20 % → ~190 µmol/m²/s → ~12.3 DLI Low-stress establishment 👉Days 8-14 | Establishment 30 % → ~280 µmol/m²/s → ~18.1 DLI Early vegetative growth Days 15-24 | Early Vegetative 40 % → ~375 µmol/m²/s → ~24.3 DLI Active biomass build-up Days 25-34 | Late Vegetative 50 % → ~470 µmol/m²/s → ~30.4 DLI Pre-flower development Days 35-42 | Stretch 60 % → ~565 µmol/m²/s → ~36.6 DLI Controlled stretch phase Days 43-70 | Main Flower 70 % → ~660 µmol/m²/s → ~42.8 DLI Peak production phase Days 71-77 | Ripening 65 % → ~610 µmol/m²/s → ~39.6 DLI Maturation and resin development Days 78-84 | Finish 55 % → ~515 µmol/m²/s → ~33.4 DLI Fade-out / reduced metabolic demand

@SleepyChow, die Sorte hat mir in jeder Hinsicht so gut gefallen, dass ich sie einfach erneut growen wollte. Zudem war mir der letzte Grow etwas zu stressig - dieses mal wirds wirklich hands off! Danke dir :)
