Heat problem

I was supposed to get a 2x4 tent but they didn't have any.
So I bought a 2x2.
I only have a batwing. My temps are hitting 94°F.
So I plugged in the A/C as a last resort.
3 seedlings died Only one left...but she'll make it
Now I'm at 76 steady.
I have a 100CFM intake and a 230CFM exhaust (both axial fans)

Do you guys think that if I buy a cool tube it would solve my problem?
I'd like not to use the A/C during winter...in Canada, it's cold.
That is, if I can find a cool tube under 22" long...

Any help?

I would think if you hooked the 100cfm up to a hood and just used a passive intake and pulled cool air in the tent from the now passive intake you would be good as long as you are venting the hood outside the tent.
Provided you dont have a 1000w going...hehe

So, you run a duct from fresh air to the hood pulling or pushing the hot air to a duct, venting outside the tent using the 100cfm fan and the the other fan would just be used to suck fresh air into the tent creating the negative pressure.
you did not mention a scrubber or the wattage but it could be tweaked if need be but you should be able to get those temps down.

no I have a 400w Lumatek ballast running at "250w"

250w!
oh ya no problem!
Should be able to kick it up to 400w!

hmmm,
edit:
I just noticed the fans you are using. You may need it invest in a inline fan to pull cool air in the tube\hood and hot air out. I don't think those little fans are gonna generate enough volume.
