We are producing sprouted Barley. Still have some kinks to work out. Would love to talk to people that have the system. Several leaks in the tray design and it will take time to patch each tray as we find leaks. We think we have the temp and humidity under control. Have discovered mold will grow FAST so must keep the environment a steady temp. Cows and pigs eating the fodder but horses walking away from it. That could be because they currently have pastures full of green grass.
