Open before heat builds
Use a thermometer and vent before midday heat accumulates. A greenhouse can overheat quickly even when outdoor temperatures feel mild.
Greenhouse guide / 01
For a first greenhouse, keep the job simple: observe heat and moisture, move air, and keep the space clean before adding more crops.

Use vents and gentle circulation so foliage dries and cold or humid pockets do not linger.
Check moisture below the surface, then water in the morning so leaves and benches can dry before night.
Remove spent material, inspect new plants before bringing them in, and clean trays and pots between crops.
A greenhouse changes timing; it does not eliminate light, temperature, spacing, or pest pressure.
This guide is a starting checklist, not a greenhouse climate-control system or pest diagnosis. Use a thermometer, follow equipment instructions, and check local Extension guidance for your crop and climate.
