pirahna beneficial fungi

i got some of this stuff a while ago and left it outside when it rained.
it is in a sealed ziplock but it looks like moisture got inside and made the color slightly darker and less powdery. is it still usable or should it be thrown away?

Ouch, that stuff isn't cheap. It should be fine, even if the microorganisms god wet, came a live and them died, the worse that will happen is they will do nothing for you.

Dont throw it away... It may be less potent, but it should still have some effect. It wont hurt your plant.

get some new stuff and keep it dry. i was under the impression that the spores were dormant until used. they need stuff to live, so if you didnt use it right away, then they might not last much longer. if anything, i wouldnt use it on all of my plants, just in case the dead spores have a adverse effect. id imagine the fungus is only effective when its alive.

guess best bet is to try it on some other type of plant and see how it effects

I bought some of this stuff while back used it but didnt do much of anything for my plants so I never used it again.I only paid like $15 for a few ounce container on ebay new free shipping..Dr Hornsby make it I think
