I have nearly finished learning how to do this successfully and consistently without any grow medium, no soil. First time doing multiple trays of daikon radish at the same time. Not ideal germination, but I know what I did wrong. I soaked the seeds in two containers, started several hours apart, then mixed them. The speckled peas are doing very well at this point, almost all seem to have germinated, and I was very careful not to over stuff the tray to avoid rot from anaerobic conditions. The only inputs are polypropylene trays, seeds, hydrogen peroxide, light, water. The shelf is ~12" by ~22", the trays are ~13" by ~10" so it takes up minimal space while allowing for 8 trays, the bottom shelf and top shelf used for storing excess trays and hydrogen peroxide. Now that I know this method is actually feasible, I will be doing a better job of tracking exactly what I do and the weight and time with the tracking app I used AI to help make.

Any feedback is greatly appreciated, and I'm happy to discuss anything constructive regarding what I'm trying to achieve, thanks for reading! I hope to be able to grow for others doing this in the near future, I've already given some trays to family members who enjoyed them. My area in Chicago has many people interested in healthy fresh foods.
