Ok. I got a 400 watt light with reflector and balast. I am going to be using part of my un heated building to grow. Wanted to build a 3x3x7 plywood box with 4in exhaust fan. will be using ona to help with the smell. What is the smallest box i can build using the 400 watt light and not burn my ladies.

According to the Jan 09 issue of high times:
250 = 4x4
400 = 5x5
600 = 6x6
1000 = 8x8
It also states "for spaces smaller than 4x4, you may consider using flouros ( T-5 or T-8 )

Having said that, I have a 400w for my 4'x3'x8' cab and it covers it all great. I wouldnt go any higher and could probably get simlliar results with a 250w. The 400 gives me a little heat to deal with.

here is gets into the teens but not sub zero temp. will the 400 watt give me enough heat without a heater? this is gonna be my firts time trying this and want to get it right the first go round.

You will need a heater. Remember that in flower your lights are off for 12 hours at a time.

would it matter what size plywood i got (thickness)?

 

[desertrat]

nope, not even if you insulated it. you will need a small space heater for when the light is off.

thank you desertrat i try to read as much as possible but still have questions thanks for your help. first timer

It isn't that complicated. Plug one of these babies into a space heater and you will be growing in style. The link is only an example - they are around the web for cheaper...

i have to get timers for light's and space heater and getting ready to get lumber for my cabinet. going to be ready by end of the week i hope. starting from seed how close can i hang 400 watt to dirt?

 

[Picasso345]

As far as possible away for seedlings - 3 feet or so, moving closer as the plant gets bigger. At about 2 weeks, about 12 inches away is good.
