long as they are cooled correctly, you can get them close. 600 ballasts are usually more efficient then 400s as well. 1000 will have the best light penetration.
Racerx Reviewed by Racerx on . Is this a good setup I want to get this and run the lighting with a 400 watt ballast with both hps and mh. Would 400 be enough, if not what lighting would be needed to run 8-10 plants? Rating: 5
