Hello - Would Co2 be practical and benefit a set-up such as a - DWC with three (3) 300w 9U Feltz 2700K/6500K dual spectrum CFL's, in a 2'WX5'LX8'T, 8 - 16 plant, ventilated closet room? Is the room to small for Co2? I don't mind the effort but don't want to completely waste money & time either. Would using a Co2 emiting Bag(s) nearly equal Co2 by a bottle? Any input is sure welcomed. Thank you very much,
