Grow Box questions

[glasshouse]

I want to construct a lightproof box to grow 2 plants at a time approx 2 foot x 4 foot.
What is best material to use?
What type of lights and how many would i need?
How many fans would i need? Would I need intake and exhaust fans or would just exhaust do?
Can i use the fans that are used in computers I have a budget of £500

Get some black plastic sheeting to cover it...the more mils the better. You could probably fit 2 flouro fixtures in it so four 4' flouros or a HID...depending on how much height you have to work with. Just an exhaust fan is fine if you decide to use flourescent lighting. Make sure there is some holes to draw air in.

High density 3/4 particle board..

1 250w HPS ballast kit..,bulb..

2-3 fans,new, high volume pc/case fans will work with 12vdc transformer/power pack..120vac fans of same size are ideal..

This size of box works well for flowering early clones,,or for full scrOG grow..
