Sorry im an idiot, was tired late last night an i posted the size of the flower room not the flower space (space taken up by pots):

Really the space will be: 6.6 x 6.6 ft = 39.6 sq.ft

so having 27 plants = 39.6 divided by 27 = 1.46 sq. ft each plant.

Lumens per square foot:
1x 600w = 90,000 lumens so 2x 600w = 180,000 lumens
180,000 divided by 39.6 sq.ft = 4545 lumens
smackhead1984 Reviewed by smackhead1984 on . Grow room size plans: Lighting/Lumens/Space per plant? Got a few plans i wana check over if any of you guys can help me that'd be great, So far my plan consist of a grow in a rectangle spare room. The room will be split in two by a curtain made of white, light proof, sheeting. So there will be two grow rooms running at once, so that as plants come off veg an go into flower more can be placed into veg. Veg room = 1/3rd of total space Flower room = 2/3rd of total space Rating: 5
