Soak Wheat Seeds For Less Time In Warmer Summer by: Eryn - Editor HealthBanquet.com
During the summer, you may only need to soak the wheatseeds for your wheatgrass growing needs, from 6-8 hours. So make sure you are not over soaking them.
Also, make sure you have acquired the right wheatgrass and barley grass growing seeds.
In regards to the barley seeds, make sure you have purchased the "whole" barley seed. You do not want the hulled barley, which means the hull has been removed. You want the whole and "unhulled" barley seed if you are to grow barley grass with it.
