What's the difference between using 100w of LED at 30/40cm from the plants versus having 50w of LED at the same distance? Or for example, with 400w of LED at 40/50cm, would they grow x(2, 3, 4) times faster?
I takes days to talk about light, lightdistace and growspace
i try a sshort version
Iam just tlking about LED quantumboards, because they have most effiency
for each square 60 cm ( 60x60 cm) you will need 100 watt of an high quality quantumboard
the lighttdistance is in the beginning on 70 cm... plants grow towards the light
for more info just DM me
