Snow Storm Ultra Say's it's derived from potassium hydroxide, which is considered a mutagen to living tissue. BetterGrow Hydro Online - Snow Storm Ultra by Emerald Triangle
Not too sure I'd trust my genetics, nor my family health to that stuff...even though it may be at inert levels. There are safer alternatives...like water.

Like OldMac said...spraying the pollen works. First, it sticks to whatever it's sprayed against, and I'm guessing it 'drowns' the pollen rendering it inert.

If in pollinating my ladies I have an "unauthorized release" of pollen, I'll immediatelly raise the lights and spray everything (pistils, leaves, under the leaves, soil, walls...) with tapwater. (except that which I just pollinated on purpose, and don't spray)
Rarely a rogue seed.

Use care when spraying nanners in the lady-buds. IOW, don't repeatedly spray the same nanners. Once or twice should do the trick. (creates a mold scenario)
Rusty Trichome Reviewed by Rusty Trichome on . Found some male bananas... Week 4 I've just gotten into my fourth week of flowering and while I was doing my daily check I happened to notice a couple of male bananas on one of the girls. I had been having some pH problems that I finally got sorted out, so I assume that was the cause. Now I'm just interested in minimizing seed production... I read somewhere that purple maxx sterilizes pollen in hermaphroditic plants and I was interested in testing it out anyway, so that was looking like my method of choice. But at 30 dollars Rating: 5
