When taking tender young seedlings from the home to the greenhouse, it is important to remember that sudden temperature changes may affect the seedlings' ability to continue thriving as they did in the home. Proper care of the seedlings, for even short-distance travel, is essential to ensure the seedlings' continued health and vigor.
Warm the greenhouse to an ambient temperature as near to the home's normal warmth as possible. Water the seedlings to be moved and allow them to drain.
Grasp each individual seedling pot, or "flat" of seedlings, placing them with care into the bottom of the cardboard box. Avoid cramming the box too full, to prevent accidental damage to the seedlings' foliage or root systems.
Replace the lid on the newly packed cardboard box of seedlings. Ensure that no seedling foliage is caught between the box and the lid.
Transfer the box of seedlings from the home to the greenhouse, as quickly as is safe for the weather conditions.
Unpack the newly transported seedlings when they are safely in the greenhouse, placing them on a stable surface away from direct sunlight and out of drafts. Make sure there is ample space between each seedling to prevent tangling or tearing.
