Kc, Thank you! It has been very hot here as well. We have also experimented with sowing seeds in our basement near a south-facing window and they have also germinated well!
We usually start our fall seedlings on May 31st for pumpkins, butternut squash, other winter squash, fall cabbage, and broccoli. We also plant multiple successions of
root crops, greens, summer squash, and cucumbers throughout the summer for continual harvests.
I love your idea of starting seeds on a covered porch.
