So I put some tape around the edges -.- hope it helps...

I decided to bring it back, and am now trying out a silver star hood. Here's a link to it http://www.progressive-growth.com/prodimages/reflectors/silverstar_reflector_large.gif I can center it into the room if I want + apperently hoods are better than cooltubes. So win win.

Hello, I'm wondering if my Cool-Tube should have the bulb centered in the room? As the room is 4x4 and the cooltube is 2.5 the bulb's placement is naturally more to one side. Does this matter? It does have a reflector over it. Should I try finding a smaller tube? - Thank you

The model is a Can-fan 4 HO

Hello, I have a 4 Inch Inline fan and the problem is that it seems to be pushing air through the middle edges of the fan where they cross over and attach with screws? Does it need a cover or something? + think it's probably lowering it's ability to push air into the other room..

It's a lettuce grow in Japan, they change the lighting throughout the day to simulate night time some how with the Led lights. Least that's the info I've found. Didn't know that was possible with the led's. http://www.gereports.com/post/91250246340/lettuce-see-the-future-japanese-farmer-builds

They look like there t5/led's combined? But they seem to be in one fixture? Here's the link - http://media.tumblr.com/9dd0fd5806905b4cfa556f199a922882/tumblr_inline_n8ga0sC9Wj1qzgziy.jpg - Thank You

Hello, Ok, so I'm setting up a new grow area which is in a cool cellar in my basement. I'm going to be putting a 4x4x6.5 tent into it. The room it's self has a 4 inch ducting into it. My equipment i'm using is a 600 watt with cooltube and 4 inch inline fan. My issue i'm having is it being quite...

Hello, I went to a hydrophonic store and asked for dolomite lime. They were unfortunately all out, and said they have calcium. Isn't dolomite lime calcium anyways? I was looking for the powdered type I'm use too... But the guy said it's better, and you add one tbsp/gal of median. So I'm...

I'm still thinking if I can cool the room a 400watt hid will produce the best yield. Can't see any led lights that can get close to the output i'm looking for. For fan noise I'll just put some egg cartons to outline the walls of the fan room like a ghetto man studio to dampen the noise + rubber...

Hey, with 1/2 as many watts the Led's yielded 75 percent of what the 2 - 600 watts produced. That's a considerable difference, what kind of led's are you using and brand if you don't mind me asking? Do you have any proof of pictures on that, because those yield differances are so far between...

Hello, The heat in the box is the only element that I'm concerned with , I'm able to deal with it, I'll have a variable controller for the fan so temperature changes shouldn't be to much to deal with. I've heard that it's quieter to run a bigger 6" fan low than, than to run a smaller 4" on...

Thank you for your reply, If I mount the filter outside the room wont my air in the flowering room become stagnant though? I'd need an extra fan to vent grow room still for fresh air.

Thank's for you reply, I enjoy any and all advise. So, I'm still wonder about extracting air from the Ballast room. My concern is If there's no intake for it than it wouldn't work effectively. I've currently got the bottom chamber and top chamber air tight from one another beside ducting which I...
