Wow where to start?

First light ā?? More is better and 600w is better then 400w. The more light the bigger and better the buds will get. Heat is always a concern and should not be overlooked. With any HID you choose you need to have the ability to bring air in from the outside. Move it though the light hood and back out the other side of the room. If you canā??t do that then you run a big risk of heat causing you many problems. Only one of which is turning female plant into a hermie and producing seeds instead of buds.

Mylar lined walls will improve side to whatever light you choose to use. For odor control you need a carbon scrubber. What about using a few of the 125w compact fluorescent lights? http://www.discount-hydro.com/GardenLightFluor.asp at the bottom. I think you can get a better price on eBay. They will save you heat and they will grow your plants just fine. They will not produce as mush as HID light but you may not notice the difference. A few of them would be close and you could use them as side light too and that will increase the overall weight at the end of the grow.

Is there anyway you can change the door so you can make air in and air out in the door? Save the owners door and just replace it when you move. You can use a carbon filter in the door as a passive or even an active exhaust.. Bring air in from the bottom of the door and exhaust out the top. It could be done with a little imagination.

I do recommend you get a good book. Forums are full of crap information and you need to know how to tell the difference.

I recommend a copy Jorge Cervantes book "Indoor Marijuana Horticulture the indoor Bible" you will use it as a reference for many years to come the ISBN number is 1-878823-29-9 he may have a new one out by now, Iā??m not sure.

Good luck and welcome btw.
Zandor Reviewed by Zandor on . FUCK! I'M STUCK!! Hey gang. I'm a first time grower, still in the process of getting my growroom set up and of course, I've hit a snag choosing my lights. I've read that anywhere from 25-50 watts per sq ft. is neccessary to grow good green. I have a closet, 12 ft. sq. total. I was thinking about 3 or 4 plants to start. I'd say a 600w HPS light would be the best bet. On another site I found that a 400w HPS light is more than adequate to grow 4 plants in a 16 sq. ft. room. What should I believe? I want to Rating: 5
