Frequently Asked Questions

What size walk-in greenhouse should I buy?

For most home gardeners, a 6'x8' or 8'x10' walk-in greenhouse provides adequate space. Consider your available yard space, local building codes, and growing needs. Allow extra space for walkways and storage. Larger models (10'x12' or bigger) are suitable for serious gardeners or small-scale commercial growing.

What's the best material for a walk-in greenhouse?

Polycarbonate panels offer the best durability and insulation for walk-in greenhouses, though they're more expensive. Heavy-duty PE covers provide good value and UV protection but need replacement every few years. Metal frames should be powder-coated steel or aluminum for rust resistance.

Do I need a permit to install a walk-in greenhouse?

Permit requirements vary by location. Generally, permanent structures over 100 square feet require permits. Temporary or portable greenhouses often don't need permits, but check local zoning laws and HOA regulations before installation.

How much ventilation does a walk-in greenhouse need?

Walk-in greenhouses need ventilation equal to about 20% of the floor area. Include roof vents, side vents, and possibly a fan for air circulation. Proper ventilation prevents overheating and reduces humidity to prevent plant diseases.

Installation & Setup Tips

Site Preparation
Level the ground and create a solid foundation. Consider drainage and sun exposure.
Assembly Planning
Read instructions thoroughly and organize parts before starting. Consider professional help for complex installations.
Climate Control Setup
Install ventilation and temperature control systems during initial setup for optimal performance.
