Boiling it and then letting it cool should do the same thing, but a bit faster.

I may just do that, althoguh right now im thinking it may just be easier to increase the dimensions of the box to fit a cool tube. That way i can raise/lower it as desired within the box, rather then having it stuck at the top, making it sucky till the plants are a certain height.

Here are the fans I was planing on using http://www.quietpc.com/gb-en-gbp/products/120mmfans/ac-arctic-f12-pro Will these be hard to wire, or the same as any other pc fan? I'm starting to think this space is just too small for a hps, even a 250w, although it has almost the same dimensions as...

Well the 250w is looking much more practical, also considering supplementing with some 6400k cfl's during veg and switch to 2700k during flower. Will 2x 57 cfm fans as exhaust keep this cool enough? Or is one enough for a 250w?

Cm, as said in the origional post.

Bump, no replys? :(

Im planning my next grow, but have only grown with cfl's before, so i have a few questions regarding HID lighting. Im growing in a 70 x70 x 100 cm tall box that is currently under construction. Will a 400w hps without a cooltube be too hot? I was planning to place 2 pc fans at the top for...

I have never seen Y splitters, but i just buy a 2 pack of sockets from the local b&q and wire them in parrallel(£1.50 for 2). It's pretty easy to do and right now i have 10 fixtures equaling 200 watts of 2700k for flowering. Hope that helps

You don't seal the bottle, but you need something like an airlock to ensure the yeast is respiring anaerobicly, i.e without oxygen. If the top is open, it will respire aerobicly and you will get no c02.
