yup, its a product like Superthrive ... it does a very good job of promoting ROOT growth, so its very handy for cloning ... you will hear wondrous stories that it changes sex, promotes females, increases yields, increases potency, cures cancer, and makes your penis double in size overnight ... it ONLY promotes ROOT growth, and it does that very well ... it also kills young seedlings if used too strong ... I grew for 40 years without it, very over-rated in my humble opinion ... :smokin: and the damned stuff didn't super-size my penis, either
