Today on Just Grow Something, you’ll learn what to do indoors before hardening off, a simple step-by-step hardening-off schedule (including temperature guidelines, shade vs. sun, wind protection, and watering adjustments), and what to watch for when you transplant.
We’ll also cover the mystery variable of purchased seedlings and how to treat garden-center starts if you’re not sure they’ve been acclimated.
Then, in the second half, we’ll talk about how the process changes when you’re using a greenhouse, cold frame, or high tunnel and why protected structures can help without eliminating the need to transition plants carefully.
Let’s dig in!
