How does it help with disease resistance?

What can humans do to help prevent getting sick? Eat nutritious foods, minimize stress, etc. It’s the same with plants! A healthy soil medium is the best thing to increase your plants’ health.

If I use it on fruits and vegetables, will they be safe to eat?

Yes absolutely. Everything in our product is from naturally occurring substances that are already present in the soil and being used by your plant. There is nothing in the product that plants (and humans) don’t consume on an everyday basis.

How do I apply?

This product can be used with a watering can, hose end sprayer, irrigation system, etc. It can also be mixed and applied together with fertilizers, insecticides, herbicides, etc

Can I use this on indoor plants?
