Good luck, hope it cures the way you want.
I currently grow in Pro mix or Sunshine #4(stock has been weird this past year) and I am dumping synthetic fertilizers w/ lots of microbes. I presoaked the promix I put the seedlings in w/ clonex feed solution at full strength w/ some corn oil soap and potassium silicate(oil, surfactant, emulsifier) to smother any eggs or adults in there.are u using bubbling buckets?
You can also be proactive and pop nematodes that feed on anything moving in your soil.the key to hydrophobic pests(and soils) are emulsifiers and surfactants. emulsifiers to make the oil and water more friendly, and the surfactant to make it hold onto the hydrophobic particles/organisms. It is why many people experience failure w/ even fresh Neem oil as a pesticide. they don't emulsify or add a surfactant.
As I am doing the soap, oil, w/ essential oil drenches, I am not going to add nematodes until I have switched to the arthropods. as the oils will kill the nematodes. I am not wasting money by killing the friends I pay for!
