A type of LST (at least as far as I'm concerned :D) was applied in the shape of a breeze fan, which softly but relentlessly pushed the gentle seedling back and forth. Applied with intervals for plant rest.
LED was set to PPFD around 350 µmol/m²/s using an extrapolating calculator based on provided factory light calibration, resulting in 35cm distance and 30% power setting.
Soil moisture kept at 40–60% usually 45–55%.
Began feeding 1/4 nutrient solution from day 5.
💦💦💦 Tap water pH came back at 8.0, Advanced Nutrients pH Perfect 3-part 1/2 solution (Micro + Grow + Bloom) based on the same water came back at 6.5, fully justifying the name of the product!
Tested with HMD PH-80.
@IstrGrow, Thank you brother!
Spontaneously started my first proper sensor-controlled box grow (was planning to plant outdoors originally) under relentless guidance of ChatGPT 4 😁 Catching up on literature and best practices as I go along.
