hey phunny,
welcome and all that
my question is how many seedlings are you planning on starting?? cause 8 of those babies are gonna pull 840 true watts and approx 134,400 lumens.. thats a little overkill for seedlings. maybe flower? i would personally order 4 of them and use 2 for the first week or so then turn on the other 2 at that point you would be pushing 67,200 lumens aprox and i would imagine that should be enough..
just my thinking bro
