Well I built myself a grow box for my AeroGarden. Now cause its a AeroGarden I didn't need no fancy grow room so built me a cheep grow box. I bought 3 of the tri boards kids use for science fairs. I took 2 of them and put them together to make a box. I used tape and made sure I tape the box together on all sides to get it nice and sturdy leaving one side untape so I can use that for my door. I took the last tri board and cut it to make the top of the box and taped it down on the inside and the outside to it. Then I tape the box down to the table in my camper to make sure no light will get into it along with wont move. I then took a car visor to block the light out of your car window and put it inside the box and taped it down so it will not move to give me the reflecting sides I wanted. Then I took the extra boxing material and made 2 L boxes. On one of the L box I made I placed it and attached it on top of the grow box and cut into the grow box on top and place a fan laying down inside the box laying down on top of the grow box. this way it will work as an exhaust system to suck air out of the box and it will never show the light of day because of the L shape. I then took the other L shape box I made and attached it to the side of the grow box and cut threw the growbox and the L shape box and had it standing up to put air into the grow box. This way also cause of the grow box it will never let light come into it. Now I am ready to get my plants to flower!!! I also added an extra air pump to the system. The cost break down for grow box. 3 tri boards. $2 each $6 car window shade $5 4 inch fans 2 of them $5 each $ 10 extra air pump $6 ---------------- for my grow box $27 Think I did good!!!!
