Yeah, guys. The 600W will likely give better coverage for the dead spots that you get from bringing the light down too low especially with SOGs.

He started using the 400W because it was the only system with a switchable balast so that he can use MH or HPS bulbs when and if needed. This way closets can be easily switched to vegging, flowering and back to vegging.

He's getting much less than 0.5 per watt and he thinks that he should at least get 0.5...

Neat thing about closets is that you can have both 12/12 flowering and 18/6 vegging crops growing in the same room!:thumbsup:
