Greenhouses

The frame is a heavy duty, powder coated aluminum frame that won't rust.

Greenhouses units work best on a level, stable surface like soil, gravel, or concrete. While a foundation isn’t always necessary, it improves stability, drainage, and longevity, ensuring your greenhouse remains secure in various weather conditions.

Consider your available yard space and what you plan to grow. A good rule of thumb is to select a size larger than you think you need; this provides room to expand and ensures you have a comfortable workspace.
The right greenhouse will accommodate your growing ambitions while fitting neatly into your landscape.

Performance depends on climate and setup, but in general:
Polycarbonate greenhouses hold heat better and usually stay about 5–10°F warmer than outside (with 8 mm PC panels).
Hybrid greenhouses (PC roof + glass sides) offer medium insulation, typically about 2–7°F warmer than outside.
PC panels trap heat more effectively, while glass allows more heat to escape.

The best type of greenhouse heater depends on your greenhouse size, local climate, power availability, and plants you're growing. Here is a simple, general recommendation.

A. Small greenhouses (up to ~120 sq.ft)
Choose an electric greenhouse heater (with fan + thermostat).
B. Medium greenhouses (~120–250 sq.ft)
Use one larger electric heater, or in colder areas, two smaller electric heaters.
C. Large greenhouses (250+ sq.ft)
Use a propane / natural gas heater or 2–3 electric heaters spread around the space.

• Built-in thermostat (keeps a steady temperature)
• Overheat / tip-over protection
• Fan or circulation to move warm air
• For gas heaters: use in a ventilated area and follow safety instructions

Climate Region
Suitable for both mild-cold and cold regions: use lower value for mild-cold, higher value for colder areas.

Temperature Increase Target
·In Moderately cold regions (USDA Zones 7–9),
The typical winter minimum temperature ranges from 0–30°F (-17.8 to -1.1°C). Greenhouse heating is generally designed to raise the indoor temperature by about 20°F (approximately 11°C).
·In Colder regions (USDA Zones 5–6),
The typical winter minimum temperature ranges from -20–0°F (-28.9 to -17.8°C). Greenhouse heating is generally designed to raise the indoor temperature by about 30°F (approximately 17°C).
