I need help deciding if I should go with the 42w cfl's or the 85w. My grow box is 7ft high x 3ft wide x 2ft long. I will be growing 6 plants. I've listed the cost/how many i need/total lumens for each spectrum and a grand total of cost and lumens for 85w and 42w. 85w...

Anyone?****

Anyone order from this place? Looks good but I was just wondering if anyone has used them.

Just wanna make sure I do this correctly. I have the feeding chart from their site but one thig confuses me, it says to add like 2tbsp bloom and 2 tbsp of grow, do I mix these together in the same water? Or do I add them separately? I've just read through the forum and people say not to mix nutes.

But what if the bottom of my grow box is sealed off by the rim of the box? I plan on using like a armoire cab and some have a rim all around the bottom. I planned in using an active intake for this reason unless I could still work with a passive intake even though it's sealed off.

Thanks for the info, I'm a noob at his which is why thought hay duct accelerator would work lol. I'll probably get that combo then from their site. That should take care of my exhaust and smell. As for passive intake, with a system like that how big/many holes should I have? Could I use like a...

I updated the first post with the link

Well I've found a couple of nice duct fans that would connect to it, the one I was looking at was a 200 cfm. Is that going to be too powerful? I've read that if the air is pulled too fast the filters cant filter it as effectively. I plan on running about 12 cfl's.

I plan on getting this filter for my box- http://www.htgsupply.com/viewproduct.asp?productID=49749 I need to make sure I get a fan with the proper cfm. The site says in order to figure it out you need to multiply the length x width x height and then divide by 5 because he site says air should...

I'm thinking about getting one but I couldn't find from the site if it has a timer for the light so you can set the different lighting times. Does anyone have this grow chamber from dealzer and does it have this feature?
