i am growing in a coco coir mix ,and have problems with knats ,i have heard if you put a layer of sand on top of the mix ,it will prevent the larvae from hatching and eating my roots ,any one with any previous problems with the little buggers ,as i dont like to spray chemicals on my plants.
any help would be great ,as i love coco ,but not the knats.
thanks blackout
