For the 1000w I suggest a 4'x4' area with a light mover and for the 430w I suggest a 2'x3' with a light mover. Heat is the biggest obstacle and it will need to be addressed. Put a board(painted black facing out) across the window with duct holes. Place speaker cloth across the whole to block light and prevent pest. Your not only concernede with light leaking out, but light leaking in, which can disrupt the flower cycle.
ok it's done. arranged 50cm x50 cm per plant, thanx bobby ;).
and Snow Owl, that board is up and painted black facing the window. it's like the light's are always off looking at it from outside, great advice :thumbsup: .
im still trying to find some fabric like speaker cloth to seal the duct.
i just turned the light's on and im checking the heat regulary. i think this will be a wonderful crop, woohooo :dance:
