How to use systemic in semi hydro?

[magicatt]

All of my plants are in a south facing window some 40+ orchids in semi-hydro included. I found a filthy little mealy bug on my shooting star hoya and have decided that the whole window is going to get treated with a systemic insecticide so that this will be nipped in the bud.

Do I just mix up the solution and fill the resivoirs like I do with water?

I am determined that all of my plants will be treated. No exceptions.

Thank you for your advice.

I would mix up the solution and fill the reservoir just as you do with water and I'd also mist the plant with this solution.

I agree.

That's what I've done in the past.

Cheers.
