i have been thinking about doing this...making a 2X2X4(or 5) box with one open side. i am looking at a 170 watt hps with the agro light. i am planning on using either mylar or painting the sides white. with the one open side, i am going to have a fan a foot or two away blowing on the plant. i am planning on using spraying the leaves once a day with seltza water to give it a lil co2. any suggestions or advice would be greatly appreciated...
if u have a fan blowing on ur plant then i doubt u wud need extra co2, besides just 1 spray a day wont do a lot. mayb if u left the whole bottle in ther with the top off it wud release co2 all the time till it went flat.
