Then they go under a MH400 with Horti Blue. Growth explodes at this time.


i just picked up a t12 2bulb fixture with Philips bulb 960 lumens 6500k. 20 watt... how well will this work....

theres some dissagreements here... u say t5 4bulb fixture. another says 400w is quick and 1000w mh is quicker and t5 is slower.... but going from seedling i personally at this point believe a flouro to begin is the way to go. im going to listen to stinky. more thoughts and opinions are much welcomed.
