Hey I just saw this thread, lol. I am Cool Cab (the large one) owner myself. Now having said that, you can definitely build this thing yourself even cheaper. I only have inside pics, same as already posted. It cost $2000 US and then your seeds. There is a exhaust fan on the inside back and the cooling tube on the light has a fan in it. There also 2 other fans below for intake. A duct attached to the exhaust with the filter on the end of it runs out the back. There is a removable cloning shelf with a flouro above. All in all a good starter thing. Since the first grow I did, I have made some modifications to it.

Very cool, if you can drop some pics of yours particularly the vent system, that would be cool too. Did you use the clone shelf, heard they are no good. You can buy one of those closets from staples for 200 bucks. Go to staples. com

Here is my pic. The airflow is in yellow. The light hood has 240 cfm running through it with the inline bathroom fan on the far left - intake is on the back and the exhaust goes out the top.

To the right of that is a 290 cfm bathroom fan that pulls air from the vents on both sides of the bottom and then is pulled through the growing space and then blown into the carbon filer on the far right and then it exhausts out through the top.

Price-wise I am at about $1000 for EVERYTHING down to soil and nutes and ph testers and my tomato seeds.

How much did the bathfans cost you? So on the bottom are just vents. Metal? Or Wooden? (the closet) I am in Plastic with the rubbermaid. For the most part it has been ok for me, I was thinking of a 50 cfm, for 15 bucks and slaming that on the rear of my unit. Then I would still need one big vent or 2-3 little ones. Right??? What about the 50. I think my space is a lot larger, but far from nicer. I am just tanks and a light in a huge rubbermaid shed. The tall oversized closet one. ha ha, For now I keep the door cracked and it brings my temp and humidity to perfect. Of course if I seal it first things first, my humidity shoots up. So I need the vents to be able to close the door. Well talk to you soon, Lata.

The fans were about $125 each, but they are very very quiet. The vents at the bottom are darkroom vents. They allow zero light to pass.

The rule of thumb I hear is that you want your air exchanged at the VERY minimum once every five minutes.

What size is your space?

Very nice on the louvers and I bet you had to go with B + H right? They don't sell them at Home Depot do they? I can sure bet they are silent, but it is a hundred dollar difference.

It wasn't B&H, I don't remember exactly, but something like that. Nothing available at Home Depot. There is a DIY somewhere for a light trap...essentially the same thing....found it:

International Cannagraphic Magazine Forums - Blue_Adept's DIY light traps

People also use the black PVC piping as vents that are supposed to block light. People claim that by spraying the inside with flat black no light escapes:



For me, money is less an issue than stealth. So I went with the quietest I could find.
