Sm-90

Hey all!

Can you use SM-90 with you nutrient program as a preventative against powedery mildew?

would you start SM-90 in the seedling stage? If not, what stage would you start adding it?

Cheers!

I don't think it's meant to be used as a root drench, but it's been so long since I've used it I don't recall. It is a good product, and using it as a foliar application it would work well to help prevent PM. That said, take care using throughout flower because it might leave a bit of a residue since it's comprised mainly of plant essential oils.

I use it as a drench all the time. Helps keep lots of pesky pests at bay...as well as a great wetting agent in your medium. If even has a drench application ratio on the bottle.

Yep, it has root drench application instructions right on the package and its imo the most effective mode of application

Mayo e know if it works for combating gnats? I'm using supersoil and don't like getting that white glass stuff mixed in with my soul because I re-use it
