Black Orchid zamnesia auto flower

Helly my friend, these small flies are gnats. The easiest way to kill them is with nematodes. These are small parasites that will kill the larvae inside the soil. You can catch the adults (the flies) with yellow sticky tape. You can buy the nematodes online, they are cheap and you can not give to many. I like to dose half and the other half 1 week after. The nematodes will die when the food (larvae) is gone.
