I finally have the ideal setup for hardening off my seedlings. I installed adjustable shelves on the backside of our woodshed. Each shelf is just big enough to hold one tray, the roof overhang extends far enough that they don't drown when it rains, the area gets morning and late afternoon sun so it doesn't get too hot. And the building provides a bit of residual warmth overnight. After years of tripping over trays on the ground, and having to rescue poor little plants from drowning, this is just wonderful!
