Funny Farmer i was just comming back on to ask IF I should use 2 400 watts? due to having a 400 watt system in flower right now for 2 plants and thinking im gonna use that one for the veg..Put Metal H bulb in...I know itll be awsome in veg mode.........Now as i said im gonna have aprox 6-8 plants in Flower first thought was a 800 or 1000 watt HPS
But thinking 2 400s then id have ready bulbs all the time not having to buy differnt kinds IPO metal and HPS of course

Your thoughts 2 400's or 2 600's?
Thinking id be able to keep temps in check more with the 400's?
and costs
BUT want a good high yeald and tight ass buds!
