Hello from my grow in France. Love listening to the show and I learn a ton, thanks guys! Just wanted to share what i do against annoying gnats. It s ultra simple. I just place a physical barrier :a very fine net on top of the pots so air circulation is good but gnats cant get in the soil to lay their eggs. If eggs are already in the soil, then they can t fly away and reproduce with other gnats and eventually die. It s been working great for me and i never hear anyone talking about doing this so I thought I d share. What do you think?
