Biological Inoculants

Hippy guy Hippy guy Hippy guy

Live biological inoculants have become an important part of indoor gardening.

Their use was actually pioneered in our industry many years ago for use in both soil and hydroponics gardening. Some of the ingredients in these products are naturally occurring in the earth, but most of what you'll find here are natural living supplements that are custom blended.

There are three main groups of live inoculants - Mycorrhizal fungus, beneficial bacteria, and live microbes. Some manufacturers supply them separately, and some combine them together, but our experience is that these products absolutely rock!

Keep in mind that all biological inoculants are very sensitive to the chlorine from city water supplies. If you use any live inoculants, we recommend using R/O or well water for your plants, or let your water sit out for 48 hours prior to use to let the chlorine dissipate before use.
