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:
