This 10G blend is exclusively focused on the treatment of aggressive Trichoderma Harzianum presence in mushroom cultivation environments along with other common bacterial and fungal contamination types. This particular blend cuts the incursion of Trichoderma on cakes down drastically - an effect that amplifies over time as fewer spores are released into the environment.


This blend does not increase fruiting productivity - in fact, you will see a reduction in fresh weight somewhere between 10-30% over a healthy, non-contaminated substrate. This blend is intended for those who wish to treat Trichoderma incursion that appears during or before the first flush. Trichoderma is a nuisance to deal with, and unfortunately, severe trich incursions require severe treatments. This blend is, however, 100% natural and USDA sanctioned for use with food-stuffs - there are no chemicals utilized to drive efficacy.

Just-the-Trich can be used in the following ways:

Substrate Spray: Simply add 2G to a 1L bottle, and spray your substrate when spawning to bulk, repeat weekly.

Tent Spray: The same as the substrate spray, only you spray the inside of your tent or fruiting chamber to proactively treat Trichoderma in the growing environment itself.

    This stuff is a total necessity for me. Especially growing in a small space in my room with who knows what floating around the air. I did a test run with one tub with no spray and one with... The one without got contaminated before fruiting but the others worked just great!
