Has anyone used Diatomaceous earth in their potting mix, to kill or prevent fungus gnats?
I will be using it for the first time tomorrow. Im seeing a few gnats on and off. They seem to die off when I let the soil dry out, and then come back after I water the plants.
I didn't have this issue when I was cropping in my 20x20 grow room because I was spraying neem once a week on vegging plants.
I dont really want to start spraying neem oil in my 2x2 tent. I also dont want to shuffle plants in and out every time they get sprayed down.
Any thoughts or ideas?
That's some cool stuff
Thanks. Its a skill I get to show off once a year. Lol
