i'm having a problem and need some advice for people that have used the egg Parasite - trichogramma spp.
that come on a card . I can't get mine to hatch... and subjestions?
@GreenSanta know anything about these?
nope, but I have had mixed results with anything I have had to hatch myself. most things need morning dew I think... If I have the option between eggs or adults and there is a problem in the room I would always go for adults. (exception being ladybugs, but would still buy larvae over eggs, adult ladybugs are kinda useless for pest control)
I did hatch praying mantis in the budding room under 12/12, I sprayed water on the egg casing once a day, some time, lol whenever I thought about it, near the end I forgot it was even there and one day, weeks later, or maybe months later, walked into the grow room and it was full of baby praying mantis. They didnt survive the environment or the escaped, it's really hard to actually keep any beneficial alive for very long in a budding room. I am experimenting with various mulch, mulch gives them somewhere to hide with high humidity. The praying mantis egg casing was hung on a lower branch.
