I am so disappointed about all this! Even just 2 Autos would have been enough bud to get me through till my Wild Roses are ready. Just one, nope, sorry don't think so! At least not unless I get 2 oz dry, which is doubtful! Anyone get a yield like that off an Mi5? As for the light period, I'm not changing it for a plant that won't even be done until a couple of weeks before the Wild Roses. Wouldn't that hurt my yield on the Mi5? 20/4 is what I have all my ladies on right now. I only use my HPS 2 hours, twice a day because I need my Hubby to install my inline fan to it and cut a hole in the ceiling, which he hasn't had a chance to do yet. So, early a.m. before I need to wake my older kids up, I put it on and leave the door open. Then, I do the same once they go to bed. Lame, I know, but better than not using it at all.
