he still might mean 8x8, can never be sure of someones intelligence chitown

I thought he meant 8 x4 for some reason. I also put cat food in the coffee pot this morning. WOW. Lol, try a 600 if yu can cool it. Just pump that air right out. Or maybe a 400 is better.

The one knock that I used to read about the digi ballasts is that some people said they break down on them a lot, and that they'll only take certain types of bulbs. Have some/most of these issues been resolved now, or are these things still hapenning?

resolved. no interference, no breakdown and whatever bulb I stick in. That is my experience with 2 purple lumateks a 400 and a 600 that I run full time interchangably. Plus the come in a real pro box. Lol, WARRANTY too.

I thought you guys were fucking insane when you were saying two 600's! It is litterally like 32 inch by 40 inch closet! It is more like 7 sq feet, with a four inch cold air in, average 20 degrees outside air (winter...only time it will be running) and two four inch outs that all kick on with a cooling themostat......so do you think one 400 watt would be enough, I would only want to grow four girls, and start to flower them at 12 inches tall. Thanks for all the input fellas....here is my closet......so if a 400.....what unit and from where, I have to get this som-bitch for my next run that starts in two weeks! Thanks again

would this be sufficient? and is the bulb a decent bulb?

you need a 400 i would say, i can't comment on the equipment though as i'm not from the states and we get different stuff to you guys

Three six hundreds, you might as well have the sun in your space. I would go with a six hundred if you can get rid of the heat, otherwise a four hundred. As stated, six hundred watt lights are the most efficient watt for watt.

i have a 600watt hps in an 8 sq.ft closet.. very nice, gets damn near tropical if u dont have pleennttyy of ventilation tho..

You want tropical, move to florida. I was wondering by your moniker, you growin' haze in that closet?

I bought a 600w ballast, hood, and digi ballast off ebay for 350. I didn't think it was a bad deal. I think it was MGS Supply. I am growing in a 4x2 grow tent.

Good luck...

I went with a 400, that is 55,000 lumens.....seems like plenty, temps have been pretty steady at 78 dgerees....

Good choice I think. I'm in 5.5 sq/ft. First grow was with a 250w Lumatek and I finished with 5.75oz with three plants (.65g per watt). I've since upgraded to a dual 250w (two lamps in one air-cooled hood) setup in the same space.
