I was only able to get 3 Cherry Tomato seedlings and 1 Winter Melon seedlings. This is a germination rate of 16.7%
I actually got a decent germination rate from my Cherry Tomato seeds. Out of 6 seeds, I got 3 seedlings (50% germination).
However, I only got 1 of 12 Winter Melon seeds to germinate and none of the two Chinese Pumpkins nor the two Kabocha seeds to Germinate.
I think the problem is that the APS-24 unit is too shallow. Since the APS-24 is only 2 inches deep, I can only cover the seeds with about 1/4 of soil. I think the seeds need to have more soil on top and below.
Last year, I used the APS-6 units to germinate the bigger seeds (Winter Melons and Pumpkins). I wanted to save space and try to germinate in the APS-24.
Obviously, that was a bad decision.
