I Watched The Mr. Green Video For The Newbies. He Has Some Weird Methods But I Noticed He Said He Sprayed Carbonated Water On The Leaves For Co2 Absorbtion. Does Anyone Have Success Or Tried This Or Does Everyone Haul A Big Co2 Canister Into Their Closets??? Also I'm A Closet Grower. Do I Need To Get A Vent Van Or Am I Ok With Just A Regular Circulating Fan???
