Nice set up. Im a newbster with knowledge. Im going to say according to some of the gteat growers ive met, it depens on how many plants youre planning to grow. One plant=150w or 10,000 lumens=1plant. I calculate vice versa. What i mean is i calculate by lumens instead of wattage but i know to understand wattage first. You look like you have enoough room 3000watts mh/hps= 240,000-600,000lumens. Also according to the pros, Id use metal halide(mh) for vegitation. And id use high pressure sodium lights for flowering. Depending on how long you want to veg over to flowering. Ive learned that its really never too much light. Keeping the lights about 3-5 inches above plant. And a close supervision on plants. Right humidity and exaust and light cooling on your ballasts or reflector lamps. Set your fans low for plants but not directly on them. And make sure your bulbs are being cooled. Im going to follow you i want to see some great gardening
I hope that ive given you some good insight and im hoping a well known member drop some knowledge if theres no conformation of what i just gave you. I just got my tent yesterday. I have 4"6"2. Im only growing two plants but i have a 400w = 55,000 lumens/mh for vegging. And i have a 600w=86,000lumens/hps for flowering. So grow on brother. 
5 to 6 inches with a 600w hps would burn ur plants 100%Nice set up. Im a newbster with knowledge.

I keep my CFLs at 3-6 inches. an HPS or metal halide would surely burn the fuckshit outa your plants at that distance....... I dont even think a cooltube would help you that close.Nice set up.

yes yes my fault. I did totally mean 3-5 on the cfls. What i did was i had the hole hook up with cfls and thats where i waa stuck on the distance for lights from plants. Then i just switched over mh/ hps just like that. Im glad you came with the knowledge. I said i wantef my first grow to be a blast. So i went with the 400w mh for veg and i also got a 600w hps for flowering.
you will not be disappointed.. later buy better HPS bulbs but i will tell you i grew 80% with those bulbs and well go look at my journal you will see what it can do
