thanks man. So say I did buy a 1000 watt though. How far from screen should it be?

i was figuring 1000 watt because I will upgrade again in the future (box wise) so why buy 2 when all I need is one.

so with a 1000 watt bulb it would run me around 83 watts per square foot.

or maybe I will just build a 6 x 3 x 5 instead that would be cost effective in the long run. Would be 18 square feet instead of 12. bigger scrog mean more buds.

thanks for the help. I think my head stright now.

A 1000w light will effectively light a 4'x4' area. However, if you get a reflector with a rectangular footprint, you can increase that to 4'x5'. I'm going to be buying some new lights within the next couple of weeks and I've decided on the Hydrofarm Daystar.

Just a little more info to rattle your brain. It just ain't right - having your head straight at this stage of the game. :D

PC :smokin:

yeah i know what you mean man. I smoke to much to keep it stright. Get confused easily. lol

anyways thanks for the info man appriciated.

Supposedly 600 watters are the most efficient lumen-per-watt wise, also I would get two 400w or two 600w instead of one 1000w because you never know what your future plans might be and when you want to seperate them say to flower one while another vegges you can do so. The only pitfall would be that two units might cost you a bit more. You can't put two different units in a grow room that small but think about it, you can flower and veg another at the same time. Peace :)

You can't grow in that size area with a 1000HPS, lol. Maybe bake a pizza in there with it... not grow plants.

In a cabinet, your 400 is about as big as you can go before running into heat issues. You WILL need an air-cooled reflector.
