thinking about investing in a couple of 200w sonlight 200w CFLs to grow with until i get more space.

I'm thinking about building a rather low but stretched out cabinet and fit 3 of those CFLs in there and coat the entire inside with mylar, i got a decent airflow. How big heat diference is there between 3x200w CFLs and a 600w hps, i used a 600w hps earlier and i know thats hot as hell in crumped areas so could u please help me out, need to know so i dont buy more then i can handle.

The cabinet is gonna be about 20-24 inches tall, 60 inches wide and 20 inches deep...

50-60cm tall, about 150 cm wide and about 50 cm deep.

would i be getting better end result by just getting a 250w hps and go for a litle more quality and less lit up space ?

If you have a fan blowing across them, they won't get too hot. Are they spiral or U-shaped ones don't get nearly as hot.
But like I said, just have a fan blowing across them.

Didn't see those. :P
Lol. But Since they are U-shaped they won't get as hot. Just make sure they aren't grouped together and there is a fan pushing heat away. I would put an intake at one end and an outtake at the other end.
 
just have a fan blow across them i use t-5 8 bulb four foot fixture for flowering and just use one fan on rotate on hight to make a wind storm so that the stalks and stems get really strong.Never had heat problem.

Edit 6500k for veg and 2700k for flowering.
