Since I had a very good germination rate of Cherry Tomatoes in the first set of seeds, I changed the mix of seeds to have more Winter Melon seeds and fewer Cherry Tomato seeds. I only want to plant 11 Cherry Tomatoes and I already have 7 Cherry Tomato seedings.
I planted 3 Cherry Tomato Seeds, 2 Chinese Pumpkin Seeds, 2 Kabocha Seeds, and the rest Winter Melon Seeds.
Below is a picture of my APS units under the grow light. I arranged the two APS-6 units to be in the center so that they get the most light. I put my fast growing Winter Melon seedling on the side, but still under the light. Finally, since there was no more room under the grow light, I put the APS-24 seed starting tray on the side away from the light. Direct light is not essential for seeds to germinate, just the right temperature. When seedlings emerge, I will have to rotate the APS-6 units by 90 degrees so that I can put the APS-24 under the light.
