Gnat Larva on my clones roots on bottom of rockwool cubes

found a few gnat larva on my clones roots on the bottom of the rockwool cubes. I mixed 1/2 oz of neem oil in 1/2 gallon of water with 1/2 teaspoon of emulsifier and flooded the trays with my clones in them. How long do you think I should let them soak before draining the neem water?

also, they've been soaking about 20 minutes now, some of the larva look to not be moving as much and turning brown. You think theyre drowning or the neem oil is working that fast?

Yup, 20 min soak is all you need as that can be hard on your roots.
If they come back.....Try this, works great.....organic.
