I feel for ya,Sh---y😵
Had the same problem with fungis gnats on my first grow,
Diotamaesues earth and sand to cover the top, 1'' thick worked for me, but I'm growing in soil
Luck!!
Grow BIg!!
@Sparkles, I removed the top 1'' of soil added a coarse sand mixed with diotamaseus earth( not to sure about the spelling)
Don't know if it will work with coca or not, I just watered and fed right through the sand, seemed to work well👍(plus yellow sticky tabs to catch the flies)
Hope this helps👊
Later!!
@InspireMe, we had names for our buddies...stupid bitch, crazy bitch, lazy bitch...I was the first one to grab a digital camera 20yrs ago. I’m too lazy to think of another nickname.
