Why and how does fermented weed tea work?

Weed tea goes through a process that other fertilizers don’t: fermentation. In a nutshell, yeasts break the plant material down very effectively – and they add their own products to the mix, too!

Weed tea thus doesn’t only rely on the special nutrients and compounds of the plant itself. It also pack in the work and nutrients of yeast as it does its work fermenting.
