I've recently been investigating fodder systems from various companies. Just today I got an email from farm-tek with their new system. There is also a lot of info on youtube and it sounds pretty neat. The complete packages are really expensive, like around $4000...but it would be so nice to be somewhat immune to hay prices, drought, lack of hay, etc. for all the animals here. Being able to produce fodder in a small area right on site would be wonderful too. I've got a batch of grains going and can see potential problems already with mold, but I'm just using a large feed dish without holes drilled....not the trays that are recommended. Before I'd even build a small one for myself, (forget about the commercial ones), I'm trying to figure out how many pounds of seed, like barley for instance, it would take to get a certain amount of fodder, and can other seeds besides barley and wheat be used, such as alfalfa and clover? Has anyone found a site with more extensive information than just the basics available on the system-selling sites. And knowing the feed values would be good too. One site showed the barley grass growing in the dark...but some systems have lights built in. Would a regular greenhouse work, or would it need to be more protected from winter weather?
