Greenhouses

About

Greenhouses and protected growing structures can provide a more sheltered space for seed starting, propagation, hardening off plants, and extending seasonal production. The most useful structure depends on available space, intended crops, local wind and snow conditions, access to water and power, and the amount of temperature management required. Plan the complete growing space Mini greenhouses and cold frames for compact or temporary protection Greenhouse plastic and coverings for new construction or replacement Greenhouse accessories for frames, anchors, monitoring, and repairs Vent openers to support temperature-responsive ventilation Greenhouse watering tools for controlled hand watering and misting Before purchasing a structure, verify its dimensions, foundation or anchoring requirements, ventilation options, covering material, freight terms, and suitability for local conditions. A greenhouse can warm rapidly in direct sun, so plan ventilation and shading as carefully as cold protection.
