hi there

want to gladden you. I have a silverfish issue at my student residences and i've caught 6-7 of them into a bottle and put some Rizla there for them to eat. They've been living fine for about a week greedily consuming the paper. Yesterday I got high and decided to put some bits of cannabis leaves and some pollen inside.. prob wanted them to get stoned as well =]]]
well today i've found two of them lying dead on their back and one hardly moving (they might be just extremely high, but less likely...)
So I can assure you that silverfish wont harm your plants but getting rid of them wont be a bad idea anyway ))

Good Luck with your crop
