I planted seedlings for the farm today. I used egg cartons for seed pots, planting 2 seeds in each egg cup. I planted 360 seeds or so: cauliflower, onions, kale, leeks, tomatoes, peppers, kohlrabi, and collard and mustard greens. I built a frame from scrap lumber and attached a piece from my old rubber truck bed liner to it to make a water tight tray for the plants to sit in, so they can be watered from the bottom.
They are sitting under grow lights and will for the next month or so. Most of the seeds were old, so it is possible they will not come up, but I am hopeful. Once the baby plants get bigger I will either transplant them into cups or directly into the ground.
