Ok those of you who have followed my updates know I was getting a new tank. Well i got it but it was a 20gal long instead of a 30 gal tall like i thought. So now im building a hood for the tank using the equipment I have on hand.
1- 65w flurex (yard light conversion)
3- 20w 24" floro grow lights
1- 4" fan 36cfm
Ok the plan is to tape off inside front of the tank and spray paint the rest of the inside flat black. Then tape the bottom also and paint the remaining inside walls flat white. The end product will hopefully have 3 sides and bottom painted black looking from the outside in. Then clear front and 3 flat white walls inside with a flat black bottom.
Im going to use 1"x12" mdf sheving planks for all the sides of the hood. With the bullnose edge faceing down. The hood will slide over and rest about 2" down the tank. Ill use corner blocks to support the weight of the hood on the tank, and allow maxuim air circulation. The top of the hood will be made out of 3/4"x15 3/4'' pine shelfing plank with a bullnose also. There will be about a 3/4" overlap on the front and both sides.
Im still in debate weither i should hinge the top of the hood or not to make it easy to water and adjust the plants. Also in the diagrams you'll see where the fan is mounted. Im not sure if it should be blowing in or blowing out. I was thinking blowing out to make a neg pressure in the box, and to pull cool fresh air past the plants and up over the lights. If its pushed in then you would get cool air over the lights and warm air pushed down to the plants. At least thats what i think is right.
Oh yeah i think layout B is best. But instead mount the fan in the center of the back wall.(like layout A or C Im not sure which would be better) I came up with the other fan location after I already had the pic hosted. So I guess its a graphical typo lol. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_n_32.gif[/img]
