The T5HO Girls are looking great at 3 weeks in. The HPS Girls are not as full, or as developed. I didn't tie down the HPS one's because I don't really have the room to spread them open at that end of my Cabinet. I don't think it would have mattered, but again, we are putting 372 watts against 150. The T5's have almost twice the lumens and the difference is showing.
12/12 on 11/29 The T5 girls are the 3rd and 4th pics. The HPS 1st and 2nd....but I think it's pretty obvious.

OMB Reviewed by OMB on . Will 150w HPS outperform 372w of T5HO? Well, I'm going to Find out! Only really applies to me and my particular grow, but a worthy effort anyway. A couple day's ago I put two under the T5's, and two under the HPS. I think the HPS at 150w is about 18,000 Lumen?...and the T5's are pushing 35,000 Lumen. I will throw a couple pics up when the "wakeup" tonight, should be interesting anyway. Predictions? Rating: 5
