Help

Hey guys I gotta question. I have a 400w hps/mhl light an reflector on a ballast. The room gets pretty warm. I was wondering if u can buy or make a are cool tube or a way to cool down my room 10° or a lil more.. I don't wanna put a air conditioner in my small room cause they are needed in other
rooms . any suggestions are welcomed. Please send me ur ideas an any pictures are greatly needed.

yeah, lots of us use cool tubes - they're all over the place. check out ebay for some good deals.

id be careful making one unless you for sure can get quality glass, if you use something poor quality it might shatter with the heat.

a large diameter hurricane lamp would work - they are made for candles and lanterns.

this is the only picture from my current grow that actually shows the tube.

The cool tube eats lumens. But safety first right?

true. I bought it because i started my grow in a 2x4 closet with 600W haha, so i needed to cool things down efficiently.

after i've got a better handle on things, ill be going bare bulb.
