idk if he could control the heat i think that the 6 600watt would far exceed 4 1000. but thats just me.

600w is good. i will be having 1 600w on 15 plants..should be fine for even 30

As I just pointed out in the post above, they are only 10% more power. Do you honestly think they will produce more light than the more efficient 600s?

As for costs, if he goes electronic ballasts he can save almost $100/ballast, even more if he gets dual 600 watters. Plus two extra reflectors.
Compare that up front cost with a 400 watt overall savings. 400w x 12 hours x 60 day flower is about $30 for 10-11¢ per kwh. It doesn't take many harvests to start paying back, if he spent more to begin with.

I'm going to air-cool them.
Haven't went to the store yet.
Still a few days away from buying them.
Gonna run two sets of three 600w in series.

IMHO - 600's are the most efficient - but you already got 4 x 1000's - and your shit looks choice - you are set, Bra! Now the question and goal would be to replace the 4 x 1000's with 4 x 600's - then you would actually be making a diff in your energy consumption and your grow efficiency. 600's are as bright at 2 feet from your plants as 1000's are at 3 feet... using this principle, there has been a move towards smaller wattages... There is a great article on light and heat in the current issue of Maximum Yield - it is a great read and is related to your question on lighting. Again - your action looks great - nice vid!

Get Super Sun 2 or Radiant reflectors and lumatek or galaxy dual 600 electronic ballasts, you will be gold!
(the hinged glass on the radiants are so nice, easy to clean and change bulbs etc.)
What is the advantage of dual ballasts? They literally cost twice as much - so the upfront cost is the same... is it the power consumption? They have an on/off switch for each - so it does not seem like they are sharing anything that would make them more efficient than having 2 single ballasts (easier to replace singles in case of failure, right?). Am I missing something?

No, they are about 10% cheaper than twice as much
