Hi Friend! Forgive me for being an overbearing self proclaimed know-it-all but I gotta say...Hey, Super thrive has growth hormones in it. Same as VF-11. Usually coupled with a straight hit of nitrogen of some sort. It's promising fast green Growth...NOT flowery females, based on the ingredients.
Hi concentrations of nitrogen is NOT what you see in any Flowering nutrient formula. Basic root & bloom fertilizers have a low nitrogen number and NO growth hormones.
So it confuses plants to get the signal to GROW green leaves & taller faster and at the same time get the lumens & maybe other nutes that tells them it's flower time. See what I'm saying? Hermaphrodites are definitely a possibility when you tell plants to go two different directions.
Hype & urban myth is all Super Thrive & VF-11 are. I used to sell it to folks at the garden center I used to work at, it was for people who wanted results in a bottle rather than really learn what it takes to propagate a living thing. Try just plain old Nutrients for the stage they're in and let them do what they already know how to do eh? Keep it simple and leave the 'miracles' for the 'non-growers'. Happy Gardening! Best Wishes, GrowIT!
