No freezing problem here in Florida ... hooray!

What about my idea to expose the top of the black tubing to
allow the sun to heat it and of adding vents to allow the heated
moist air to escape?

The soil here is very sandy so it drains quickly.  The only concern
about the top-side venting is that when the ground is wet the heating-
venting effect could cause wicking up though the bottom-side drainage holes.

BTW:  How many drain holes are really necessary along a 100 foot tube?
