Okay quick update here.I bought the cabinet to grow in it's 2x1.5x5 feet.I have my light in there now and next month am going to buy the intake fan and outake fan.I need some help also what cfm should the intake be and what cfm should the outake be im no good with math so i couldnt figure out how much cubic feet there is and i couldnt find a calculater either.I am buying some mylar instead of flatwhite paint.Here are some pics of the plant i have in there and the light.My plant looks like it has nute burn or something on some of the leaves.There are not any bugs around so it cant be that.I think i found out why the leaves were turning yellow.I was overwatering them way too much and have switched to a three day water regime now and it might go up to four or five day regimes.
