Starting seedlings under glass gives every crop a head start, but a greenhouse is its own small climate to manage. This article covers our transplant routine step by step: hardening off seedlings, watering deeply but less often, and venting before midday heat builds.

We also share the spacing chart we use for brassicas and nightshades, the organic feeds that keep young plants stocky instead of leggy, and how we rotate beds under cover so disease never gets a foothold. Follow this routine and your transplants will walk out of the greenhouse ready for anything the season throws at them.
