How much can i expect to yield? Please help : )

Thanks for the advice. Its just in a small space , other lighting systems would get too hot? What about LED?

Really compacts\fluorescent lights just aren't as efficient as HID lighting. 200 watts of HID is going to emit quite a bit more lumens per watt than 200 watts of CFL lighting will. If you have a 400, 600 or 800 watt HID ballast with a high pressure sodium lamp, it is going to emit much more lumens/watt than the equivalent # of fluorescent bulbs. We're talking like double the lumens per watt: a CFL might just give you 70 lm/W while the 600 watt HPS is going to give you 140+ lm/W. And the way HID light penetrates can't be beat.

Of course you have heat to contend with, but even with the added cost of running a high output exhaust fan and\or an air conditioner, an HID is more than likely to save you money as well as give you higher yields.

What lighting should he use? Wouldn't any other get too hot? its only a small space and because its a hydroponic set up , wouldnt the excess heat cause too much water in the air? What about using LED lighting? I was going to use the cfl becuase that is what is included?

in a small space heat is only a prob if u dont have good air circulation. most houses have an average temp inside that is perfect or close too perfect for growing MJ...unless u live in the desert. what im trying to say is if ur house stays generally between 65-80 degrees and u have a couple fans keeping the air moving and circulating in ur cab, then u should have no prob runnging a 400w or smaller light without having temp issues. an air cooled light should be flawless in a cab and if its not air cooled, just position ur fans around untill u find the sweet spot. point 1 fan directly at the light to blow the hot air off of it so it will disapate in the enviorment and have another fan at the top of ur cab sucking or pushing air out. put a hole the size or close to the size of the fan pushing the air out on the bottem (cuz thats where the coolest air will be) to replace the air going out. its called a passive intake and it works great for cabs. or u can do the complete oppaset and put the blower on the bottem and the passive outgoing on top..good luck dude

Is that really what's included? I don't know about this tent/closet or how big it is exactly, but aren't there ports for intake\exhaust ducting? A 250 watt HID doesn't get too hot, especially if you've got an air-cooled hood with it. You're going to have to vent the tent anyways.

Im emailing the guy from supercloset atm. Im going to see if he can remove the cfl and place a 250watt HID or something similar.

thats a good call to make. it might cost a little bit more but the rewards will speak for themselves in the end.

or add the hid and use the cfl for cloning.
