Those plants are looking good. Did you use light for heat too?
I put a pan over the one floodlight we have out there (as you suggested); I believe it’s 60w. Not sure how much more to do. Can’t imagine getting too many more fruits, but there are a number of blooms. I might put a little more straw around the back of the enclosure and maybe a little more at the sides. I’m sort of surprised [but very happy, cuz they are so pretty] at how well they are doing; all exposed tomatoes in our area have now succumbed to the frosts.
