Dogs are so cool... Nice seeding and green house. I have a seed table well actually it's 3 tables stacked up like a shelving unit, just like yours. It's all fun and games until one of those thin black plastic trays springs a leak (usually in a corner).
I puttered around yesterday and this morning and got my seed starting greenhouse all set up. I got all the lights in place, set up the two heat mats with the regulator and a small space heater that is temperature controlled. I have 4 trays in it, I have 8 more spaces!
