Can you explain why you want to use 400w for flowering and 1000w for veg?
Pass That Shit Reviewed by Pass That Shit on . Co$t of running lights I am thinking about getting a med. sized sea of green started up, but i am worried about the cost of my lights telling on me. Can anyone give me a ballpark figure of how much a 400w hps light cost to run 12/12? And maybe a 1000w mvh 24/7? I am just trying to make sure i have all my bases covered before i get in too deep. And to see if i am going to need a secondary power source. Rating: 5
