I've currently got two Bubblegum sprouts (2.5" tall as of today: 13 days vegging under 210w CFL) in a Waterfarm. I've got them growing in a 2 x 4 x 6 cabinet which is divided in two: the second half has 2 3' compartments and the plants are currently growing in the first half. I am going to ScrOG the babies when they are large enough: I figure I can veg them under CFLs for a while, as I'm in no hurry.

Today I ordered a 400w HPS with a cooltube from HTG Supply. I presume I will also need an intake and exhaust fan, but was wondering if even this will be enough to keep it from overheating my 2 x 2 space?

Thoughts? I can post pics as soon as I find my camera.

you will need a good exhaust fan and possibly an intake fan. I got a 400w mh in a cooltube in a 3x3x8 closet and my temps went over 95 degrees , get a good fan such as vortex or sunleaves 6 inch . good luck and keep us posted.

I'm guessing a cooltube is a thing you put your lights inside so they don't make a lot of heat?

My present plan is to install a 6" inline fan for exhaust and possibly a computer fan for intake. I won't be able to move the cooltube too much but i'm not worried -- with a ScrOG in place I'm sure the buds will be getting all the light they need. I also have an oscillating fan blowing on the plants and, when the screen is in place, will probably keep another one near the base of the plants to keep the air circulating and avoid mold.
