Roots Organics Oregonism XL is a distintive blend of endo/ecto-mycorrhizae, beneficial bacteria, and Trichoderma. 

The species of microorganisms in Oregonism XL are specifically selected for fruiting and flowering plants with a tolerance to heavy fertilizing.

The mycorrhizae colonize the root zone, forming a symbiosis with the plant's roots, massively increasing the size and effective surface area. The beneficial bacteria and Trichoderma in Oregonism XL produce plant and root growth-promoting compounds to protect against pathogens.

Water soluable Oregonism XL helps increase nutrient uptake, encourages vigorous root systems and helps plants resist stress.

Oregonism XL contains:

6 endo mycorrhizae species
6 ecto mycorrhizae species
2 trichoderma
13 strains of beneficial bacteria
Yucca
Soluble kelp

Although developed for hydroponics systems, Oregonism XL is also effective in soil gardens.
