hey all im having a hard time finding a good 250 watt ballast i wanna be able to run cmh or hps so i need a magnetic ballast but i cant find one any suggetions would be nice thanx

its really cold in the room in which I imagine this all would go. and i guess i have a few more questions... if i set the S&P at the low speed it would still be well within the cfm range and also by going with the smaller filter i can save a little bit of space. also, would +30 cfm's...

So here's the idea. 2x Comp fans for passive intake. and the exhaust system is going to go something like this(at least it works in my head) Hydrohut Charcoal Filter Elf (150-265cfm range). -> ducting Hydrofarm Cooltube. ->ducting(maybe?) S&P inline fan TD-150(218-298cfm range)...

hey looks like its gonna be a very nice setup im subscribed. hey will the cab be light proof?

OOORRRRR could leave one end of the cooltube open and exhaust the air from the light/room and scrub it all with one system and one fan. Could it get to hot in there if went with this option? Keep in mind. -4'hx4'wx2'd Homeade cab. -400watt cooltube(maybe cmh? see above^) -Undecided...

So yea, this cabinet is almost done. The cooltube and ventilation look almost exactly like they do in the picture above, but I'm having some thoughts on how to cool and scrub the ventilation... My next question is do you guys think using 2x 4"axial fans pointing inward from the back of the...

Thanks a lot for the support. That's pretty much the image I had in my head.

What would be the best way to set up a 400watt cooltube in a 4'Hx4'Wx2'D cab? Meaning... strength of fan to exhaust the cooltube as well as how/where to put the scrubber. Thanks in advance =)

Honestly, my room is cold pretty much 24/7. Hopefully the bigger 300+ will get the job done. Thanks for the insight man.

That's actually still kinda hot. I planned on using a cooltube as well....maybe even bigger than 250 would be more sufficient?

I was wondering if a Vortex 4" 172cfm fan could cool a 400watt cooltube all by itself in a box 4'hX4'wX2'd. Cause if so, I'm in like flint. :twisted:

hey i have a 4x5x8 closet with a 600 watt hps and the temp gets well over 100 degrees if i hook up a 6 inch vortex 424 cfm inline fan to the light and pull the air through the light and out of the room and had some oscillating fans would that be enough to keep cool?

can u clone from these and the clones still autoflower?

hey is there any way to tell how many watts the portable ac units uses if it say 12,000btu how watts. Cooling power consumption: 830 W / 7.9 A does that mean it uses 830 watts? thanx
