A Greenhouse Needs an Air Plan

A greenhouse is a changing climate inside the garden. Sun can warm a small enclosure quickly, so plan how you will check it and provide suitable ventilation before filling every shelf with plants.
RHS British advice treats ventilation and shading as important parts of greenhouse care. Match them to the plants, season and weather; there is no single opening position that suits every day. A thermometer and a reliable check routine can make changes easier to notice.
Use the structure’s designed vents and secure mechanisms, keeping the doorway and working aisle clear. Arrange any repairs professionally where needed. Avoid improvised electrical equipment, loose glass or unstable props, and follow the manufacturer’s guidance.
Record unusually hot days and how your plants respond. Leave enough space for air and access as growth expands. The goal is a manageable growing environment, with attention to water and plant health as well as the appealing light beneath the roof.
