hi ppl just a quick q how far into the canopy will my 400s penetrate my plants

how tall should they be idealy for them to produce less scrott and all get good light from top to bottom

hi there

i too have a 400W...

i have read in uk420 the light should be 18 to 24 inches from the canopy

hope this is right??? if not tell me quick :O)


Peace

not quite what i meant mate

how deep into the plants wiil it penetrate

It all depends on how close you get the bulb to your plants



Well if i had to have a 400w 24" away i'd be looking at my environment and air movement

Owd

what sort of distance would you be aiming for owd
