Has anyone used this before...?

So...I'm having an odor problem...and the plants are only a foot tall, so that means when I hit the flowering stage, their going to be really smelly...what I was wondering is...has anyone tried this thing before...it would be used for a 2x2 ft grow space inside a small closet...

i have not used it but if you put it in your closet i would think that you have to keep the doors closed 24/7 so that the smell wont get out cause that may not cut it... also what are you running for your light/dark cycle and how many plants do you have?

Actually, that device was recommended by the guys at my local hydroponics store. Since this is my first grow, I don't have anything to compare it to, but it does seem to be keeping the odor in check so far.

3 plants inside a small closet. I have the leave a door alittle open to let the exhaust air out for the inline fan...dude their stinken up the hole room... I mean bad...I think of going to buy or build a carbon filter...I'm on veg. cycle - 16 on 8 off...
