When does seedling stage end

[MeanGreenEye420]

ok and how far away are we talkin i got a variety of HID lights but they put out so much heat.

I have a 1000 w MH 2 feet above it at first (maybe 2 1/2 feet)
I have one fan blowing hard right on the bulb and another lightly across the top of the soil (plants).After they're a week old about I move the light to about 18 inches.Or 2 feet at the most.Depends on the heat yours turns out.and the temp of the room and control you have over that.
Window ac units are great for getto grows ...they help with temp and bring in fresh CO2 every time it's on .And it replenishes the room with fresh cool air.Just make sure you don't have light leaks because of it.(You need to build a light baffle)

Im kinda confused is this the hood cause if so im going to build one and add fans to it to pull heat from the bulb and blow it away from my site.

Ya man put your hid on it now just be carefull not to let the heat get you. I'm haveing that problem now in my new grow area, much smaller than my last one, but I just need more ventilation. If you have a small area and you only need to cool it a little try freezing a couple of two liter soda bottles with water in them and then sticking them in front of your fan, I'm asumming you have some kind of fan in you area. Hope this helps. :stoned:
