1000w Double-Ended HPS
Buddies barn with HPS costs $300 more per/month but he's pulling more weight and better quality from it. He has 2 barns (each having 24 lights) next to one another. One's Gavita 1700e and ones Gavita 1000w DE HPS.. $300/mo power bill is cool but when you factor the losses it isn't worth it or even out...
1000w Gavita DE HPS here is $250 brown box out the door. 1700e is $1,000.
