that sounds pretty fine now that i know the values of the light! but you are much near at the canopy than me. so it is like you said the days of guessing and bro sience are over
guessing can be fine!! but for me at the begining after the switch to led. it was a catastrophy. and i feeled like i had never grown a plant before. and switching nuts to self mixed salts didn´t helped much
and that phone app saved me .
Hey hamme i also have diy led but bridgelux you have double row samsung
I have always fullpower on from seed to harvest i do this because i need to keep the plants short have only 1mtr hight and the top shelf only 80 cm
I hung the lamp a bit higher otherwise the spreading isn’t ideal anymore. Furthermore i increased the wattage to 300 watts to compensate this. One plant in the middle seems to have a small problem with the lights.
