I'm curious about the hardening off process for plants that have been growing in an unheated but insulated greenhouse. Since they receive plenty of sunlight during the day, can I transition them directly into full sun exposure? Also, how long can I keep them outside? I'm thinking of about eight hours during the warmest part of the day, but I obviously won't leave them out overnight.

From my experience, hardening off plants is more about letting them adjust to wind than just light. I usually open the doors on both ends of my greenhouse to let a gentle breeze circulate for a couple of hours. After a few days of that, I place them in a slightly sheltered spot. Light isn’t an issue, but they definitely need to get used to the wind just like any other plant you’re hardening off.
I see, thank you!
