I am in the process of hardening off some cauliflower, some celery, one cucumber, and one tomato that I grew in my basement. It is the right time to move the cauliflower outside and possibly the celery.
Tomatoes and cucumbers love the heat so it is early for them. I am going to try the wall-o-water this year to see how that works out.
It is also why I am only trying one. The rest of my tomatoes are staying safely in my basement for a little while longer.
