That is truly awesome! I love seeing kids (all kids) get involved in food production. It’s so rewarding, and they have such enthusiasm. They can go from “I don’t eat carrots” to “I grew this carrot and it is amazing” so quickly!
I looked over your other thread on your fodder adventure, it reminds me more of the sprouting jars I was doing for my own consumption a while back. If you’re wanting to upscale a bit, a fairly simple flood table and mesh frames would be my recommendation, less plumbing and less emitters that could clog and fail. Basically like the CropKing link but home made.
The best part of the fodder is you won’t need any hydroponic nutrients, high powered lighting or the ventilation systems that go along with that.
An excellent reference is “Gardening Indoors: the indoor gardener’s bible” by George Van Patten. It’s fairly inexpensive on amazon and very thorough. My primary reference for a decade! Looking forward to your updates
