That is why I cose the "other kind"...

The ducting just slips in and clamps down...

Get creative bro... but I will tell you that tape will start letting go about 2 months in...

Your best bet is with adapters from Home Depot or something...

or tape... but that's not a permanent solution...

yeah but it was free.... so i can't complain. it was on a wood stove.

i don't think i'll have much luck finding an adapter locally. i would have to order something. f that.

duct tape will work fine....i'm only gonna be living here for a couple more months anyways. then i'm moving to utah!
 
well its supposed to come tomorrow :)
hopefully


its really weird, i got an email with a UPS tracking number, but today i got a call from fed ex confirming delivery of a package tomorrow..........
 
well my ballast and bulb came!!!

it was by fedex, so i guess my cooltube is coming by ups

the ballast is really small! i thought it would be bigger

If you could keep the ballast on the outside of your grow room that might help with heat a little bit also.

thats the plan! i can actually have my ballast up to 65' from my bulb!


it also says on the box it works great with generators!

not that i'm using one but hey you never know what will happpen in the future!
 
That's why you need good ventilation...

My room goes from 75F to 120F in less than 10 minutes if the fans go off...:wall:
 
it doesn't fit horizontally so i had to make it vertical....

my temps are back down around 81-82 :)

this is with the doors open a little bit.. but i think it should get even cooler with them closed because of the suction

I am glad it's working...

and I am glad that you put the loose end of the bulb downstream...

But I am a little confused...

It doesn't fit?

What if you put the fan on the hot side of the tube.. and left the open end without any ducting...


so it would go...

room air>>>>> cool tube >>>> fan >>> outside world...

From the pics it looks like it should fit...
 
my room just isn't wide enough.. the cooltube is way longer than i thought

and yes its all very very nice. i am really glad you convinced me to get it! :)
