If your building a huge box dont forget Ventilation! an inline fan works great, but if you can drill a small 4'x4 'hole in ur wall ur set! Squirrel cage fans are noisy, but if you place some rubber padding underneath it, it wont make nearly any noise. ANd also check out getting some Mylar, i got 50 ft. for 14 bucks off HTG supply.com and it makes a hell of a difference. This place also has some cheap inline fans under ventilation, you should check it out and it will help provide you with some ideas. You should spend just as much money on ventilation as u did you light.....ok maybe a little less. but check it out. Goodluck
moisaal Reviewed by moisaal on . New Grower Needs Help! I just decided to start growing. I bought a 400w MH/HPS light on ebay. I am going to build a wood box in my closet. I was thinking of making it 4' x 4' x 2' but i am not really sure. I could go up to 5 x 5 x 2 but the 4 x 4 box would be easier to build. What i need help with is making an ideal setup with these parameters. Do i have to much light for that space? I know those lights get pretty hot and need to be a certain height above the plant but don't really know how much. Do i fix the lamp up Rating: 5
