No... neem oil is an organic foliar spray used for pest control. I wouldn’t use it at all unless you’re having some pest issue.

Unless you are having pest issues you don’t need it. If you are then follow the directions closely on how much to add to your water.

Luckily im not squeamish so dove in and opened the bud cluster to clean off the webbing and low and behold little tiny caterpillar. Will a fine net stop this?Week 23

Pest control looks like fungus gnats and larvaeEver since this grow i noticed fungus gnats flying around. I always put sticky traps down and would catch an adult every so often but always saw tons of little dots I thought was dust or fabric until I used my scope. I bought a product gnatrol and will try it. any suggestionsWeek 3

Organic IPMWhat do you all use for IPM? I got tweetmint, em-5 from BuildASoil & neem oil. I just tried a solution of neem oil, AGSil 16H & ThermX70…forgot to PH balance the solution so I came back & sprayed the leaves with a lower ph purified drinking water. I’m growing organically btw.Other. Bugs

Help identify pestsNeed help identifying these bugs. I found them under rockwool cubes in the cloner
They seem to like the moisture and were not bothering the vegetation at all. I even found them under a few cubes with no cuts in them. Is it possible that they are fungus nat larvae?Other. Bugs
