I have been so behind on my posts this spring that I think this is the first time I've shown my seedling set up. I got a bit carried away with tomatoes this year and expansion was necessary. I had my regular table with lightstand and warming pad set up as seen below.
A second window was also used and shelves added there as well. As you can see I had just a 'few' plants growing this spring.
I started to harden them off but due to roofing it got a little complicated and they had to be kept indoors until the wreckage had subsided.
