Buying Guide

Choose material for your climate

Polycarbonate panels offer rigid protection and insulating air channels for cooler climates, while polyethylene film is flexible and affordable for seasonal covers

Check light transmission and blocking

Look for translucent polycarbonate or panda-style black-and-white film depending on whether you need full light diffusion, UV protection, or temporary light-blocking for pest control

Match size and panel fit

For replacement panels, confirm panel dimensions and mounting style so sheets or panels align with your existing frame or glazing channels

Prioritize UV protection and thickness

UV-stabilized polycarbonate and thicker films (measured in mils) resist degradation from sunlight and last longer in outdoor conditions

Consider seed-starting tools for efficiency

Handheld soil block makers or germination accessories reduce plastic tray waste and help uniform seedling sizes for easier transplanting
