I am growing using coco husk. I noticed two weeks ago I had fruit flies in my grow box. I sprayed my ladies with neem oil and it killed all the flies that were visible.
I have now noticed they are all coming from with in the soil. Is there anything I can do to kill all the fruit flies in the soil.
Every time I spray they keep coming back. Luckily I am still vegging so spraying isnt a problem right now.
