Soak 1/4 of a mosquito dunk in a gallon of water for 24hrs and use it to water your mushrooms. That should take care of the fungus gnats. The dunks are organic.
I am renting out my homestead in the ouachitas of arkansas. I'd rather it rent to someone who will make good use of it. I've homesteaded on it for 3 years so there is a good start. Email me at gkrahn1981@gmail.com.
3br home + outbuildings. Already set up for chickens and small animals. Mature fruit trees and many more planted this spring. Herb garden, vegetable garden, mushroom garden.
