I'd done some reading on gb acid in the 80's, but didn't pay too much attention since my goal was to ptoduce females. It was brought up breifly at U of D (Delaware), hort program, but not extensively. It's found in some commercial rooting hormones, which I avoided since I wanted females. (I use an old school method, willow water, if you're not familiar & want that recipe, friend me & I'll share). Anyway, my intent here was to ask the right questions to help the dude find uses for his hermies & the techniques to do so. I think we're getting close to going off topic.
