BTW. HPS tends to cause stretching. Look closley & see if there are more leaf sets, or just stem stretching. If its just stem stretching, the buds will be longer, so you'll need to compare by dried harvest weight. That will be the only way to determine if your growing more bud, or just more stem. I like experimenting!
catbuds Reviewed by catbuds 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
