I've always thought about throwing acouple auto into my veg tent, for a finish room,,, least for the auto. And still veg my photos plants, Least that is what I'm hearing from Killian? I've not grown many autos myself. Least indoors. But they do have these 50/50 MH/HPS como bulbs. Might be the ticket to accomplish both?? I can't say much,, I've never grown a complete flip of autos,, so I've no idea. But I will say these combo HID bulbs sure 'brighten' up a flower room.... Keepem Green Breast
