Finished cleaning, repairing, and setting up the greenhouse today.
I had to replace some of the roof panels, robbed from a similar greenhouse kit I picked up for $200 a few years ago. The panels are fortunately the correct width, but about 4" too long (they were intended to be used as side panels). Rather than cut off the excess, I left them over-hanging the edge, since that will keep the panel edges clean. Then set up the tables, ran an extension cord for the heater, and brought all the tomatoes, peppers, etc. into the greenhouse.
This is one of the Harbor Freight greenhouses; all panels are held in place by spring clips. Those wire spring clips have a lot of tension, and are tough on the fingers. But some years ago, I needed a small spanner (don't remember what for) and cut a slot in the end of an old straight-slot screwdriver. That tool came in handy for removing & inserting the clips... and for positioning them properly if they didn't go in straight.
With nights in the mid 40's now, the space heater can maintain 60 F. degrees overnight - so this round of plants will stay in the greenhouse now. That makes room under the lights for the next round of transplants, which will be started next week.
