Currently I'm using the ole' sugar and yeast co2 production but plan to upgrade to a tank and valve asap. So, my question is how big of a co2 tank do I need for a 6x6 room?
My current set up is (budget/makeshift 4 now)a rubbermade 68Liter with all 4 seedlings 2 100w equivilant cfl's "daylight" 6500k 1600lumen and this light i got when i was in highschool to treat my "s.a.d."(i smoked way2much in highschool and mom just thought i was always tired) its like a 2 foot...
