just gonna drop this,
superthrive is snakeoil. They've never disclosed their formula, and in my personal experience, I believe its mass adoption is the fact that it has B vitamins and contributes to a placebo effect at $12 for 8 ounces.
Foxtailed flowers aren't a terrible thing, either. My last run was blasted with light (outgrew my space was NOT anticipating the explosion that happened) and I've had consistent reviews of praise despite my shitty trim job. Sure, lost a lot of bulk as a consequence, but the quality doesn't change much.
Best bet is to keep PGRs out of the grow room, period. There are some really odd plant behaviors that while they're conducive to vine type crops, they have no business in cannabis where we are concerned about tight internodal spacing for bulking purposes. Bag appeal plummets when you hand someone a bag full of speared, airy looking buds. They don't see the frost, nor smell the aromas, they see airy buds and immediately think that 3.5 grams weighed on a triple beam is light.
My patients don't care, and trust their donations are equal to the product I gift them. Still is a bit disheartening when you're hoping for bats and end up with katanas.
