Yea you need a hood that cool with a fan. The heat is bad. They have ones with the cooling tube. Ipower is good also. What I have read. I would do a good led light. You can get a good 2x4 for a good price. It will veg larger. And add a 2x2 led light. Would work great. The big lights you have to worry to much. Imop
It will grow them yes but at a price. If you have a open room yes. If not it makes a lot of heat. Plus fans on the power pack. I know it has a fan but they still get warm.
I have been concerned about the heat and potential fire issues from using HID bulbs. Venting is not a problem but I have decided too go with LED’s either way. Can you tell me what you think of this light from Spider Farmer? Thanks!

Getting better, but still a little under powered for your area with only 200 watts and I don’t like recommending chinese lights. For just a little bit more money, you could get a HLG 260W Rspec, a much better light from an american company.

X2 Not knocking the knock offs, but I know HLG QBs work!

For 3 plants. You got to remember your coverage space. In my opinion one plant needs a 2.5 x 2.5 light area so for three plants it will be tight but you can also add another light as they get bigger.
The 4K HLGs I have are the stuff. For vegetarian I couldn’t ask for anything better. The thing with those cheap lights they come with cheap bulbs.
also you will need a back up light what do you do if your lights go out how long can you wait those are things you have to remember also. you need back up stuff.
Full spectrum is the way to go. I would recommend the following for a 4x4 tent when on a budget–> Amazon.com
Sorry if i’m asking this question in the wrong thread but I’m still figuring out how to navigate this site. My question is my grow room has a tile flour that radiates cold and stays around 60 degrees. I have some thick "black" rubber mats that I can put down for insulation but should I be concerned about not having a reflective floor? If so should I paint them white or get something else like foam board with the foil backing on it? Thanks for the help!

@Mic504 I don’t think that you need to worry about making the floor reflective but I would consider raising the plants up off of the floor (your insulating mats would do this) because soil temperature is important. I am not certain what the best soil temperature is, perhaps someone will chime in on that.

Anything above 65°F Seems about right. I’ve never checked, but I know I have seen slower growth with cooler soil temps.

Same here, thanks for the confirmation.

My theoretical take on it is the any thing that is as close to it’s natural habitat as possible is best, (ie ground temperature) is prime! To make it simple 
65F should be good!

@Hellraiser @dbrn32 Has anyone ever heard of this light for a 1000w replacement. My local store is selling them and im thinking about giving it a try.

First I’ve seen of it. Have you seen ppf number associated with it?
If it’s a good light they are usually more than happy to give you this data. I would do a little more digging before you buy one.
