Hollow polycarbonate panels are popular for a reason — they’re strong yet lightweight, let in plenty of natural light, and protect your plants from UV damage (rated UV30u). The hollow structure also helps retain warmth, so your greenhouse stays bright and energy-efficient throughout the year.

Sure! Before you start, sort all parts by number or type to stay organized.
Wear protective gloves to prevent cuts when handling metal or polycarbonate panels, and use an electric screwdriver to speed up the process. It’s best to assemble on a calm, dry day — and having a second pair of hands will make it much easier.

Currently, custom sizes aren’t available, but don’t worry — we offer a wide range of styles, sizes, and colors. You can explore the full collection [here ➜ Greenhouse Collection Link] and find one that fits your garden space perfectly.

Some greenhouses are shipped in multiple boxes for safer transport. Each package is labeled with its number, so please check the sequence and wait for all boxes before starting assembly. If one box seems delayed, it usually arrives within a day or two — feel free to contact us if not!

You can, but we recommend two people for a smoother process — it’s easier to align panels and secure the frame. Treat it like a weekend DIY project with a friend!

Install your greenhouse on a flat, solid surface and ensure all joints are tightly secured. In windy areas, add ground anchors or sandbags around the base for extra support. Always close the door and vents when not in use to reduce wind resistance.

Use a soft cloth or sponge with mild soap and warm water. Avoid harsh cleaners or rough brushes — they can scratch the polycarbonate. Clean gently to keep your panels clear and light-friendly all year long.
