As I said earlier, we really need to do this experiment with equal lumens and equivalent lighting structure (side lighting, etc). But I am really intrigued with how the T5s are performing here. Couple of questions OMB...Are you confident that the group of plants here are genetically stable? By that I mean are you confident you are not seeing phenotypic variance unrelated to lighting? I ask this because the 4 girls I am flowering are supposedly seed from a single cross, but one of them has a distinctly different growth habit, ie lankier, longer internode distance, and overall "thinner" appearance. Also, are you using a single temperature of bulb in your T5, or are you mixing kelvins, and if so, what is your mixture? Apologies if you've already covered this earlier in the thread.
Chromophore Reviewed by Chromophore 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
