covers or none?

Homer is constantly experimenting. As a formal experimental model maker, he does it without thinking about it, as he was trained for decades to try different methods and only put into production what really worked.

On the same day a few weeks ago he planted lettuce. He used his seed plotter to position the seeds and then covered with the same compost and drip tape. Water amounts have been about equivalent. The big difference is that one is covered with the floating row cover and the hoophouse, the other open to the elements. The thin wire and thin floating row cover make quite the difference.
