Thats a mighty big light for a 1st go.
To get your moneys worth watt wise. Id stick in at least another 3-4 in there.
Have the SE5000 and I easily did 11 autos and fems.
Either way. Good luck with your grows. Enjoy
@gottagrowsometime, I've been using a HLG 550 R for the past few years, this is my 1st diary on here. I like the bigger bars, seems to cover much better than the board. I'm stuck with a 5 plant limit in my state, usually make the plants into little bushes, it turns into a jungle in the tent. Thanks for the comment, more to come!
