I noticed some fungus gnats fly around today...will mosquito dunks work in a Rdwc set up? Can i just toss one in my res. My girls are three weeks into flower so i dont want to spray anything.
I wouldnt the dunks contain the chem bti, it is labeled safe for humans and wildlife but it is not to be put in water for human consumption, so I'm not sure if i would want to smoke that shit because the plant will absorb it.
