Ask Ed: Grow Tip – Trichoderma Harzianum

CANNABIS CULTURE – Want to protect your plants against root diseases and give them a boost?

There’s a fungal organism called Trichoderma harzianum that develops a symbiotic relationship with your roots, surrounding them and feeding them nutrients in return for their exscates.

It also produces toxins that kill pathogens and digest them as food, thus protecting the roots. There are several products that contain this fungus.

You can find more information on this fungus and root diseases here or in Marijuana Garden Saver on page 97.
