hoodrider Reviewed by hoodrider on . Mycorrhizae Mycorrhizae is a symbiotic root fungus that roughly 90% of the plants have in nature. I figure this is absent in home grows, particularlly the indoor grows. I found this for sale: http://www.bio-organics.com/Mycorrhizae_Products.html#MineralsStart I was wondering if anyone here has used this or a similar product. What were your results? Rating: 5
