Greenhouse kits are large and heavy, before you order, please text or call Henry Yu at 630-408-2201 to discuss details for purchasing, delivery, and installation.

Each greenhouse weighs 1500 pounds depending on what Optional Items you purchase. The longest pipe is 20 feet long. You need an 18 feet (minimum 16 feet) trailer to take 1 to 3 greenhouses. Bring many, such as 10 tie down to secure the materials on the trailer, so you don't lose all pieces on the road.

26 foot long U-Haul box truck is the best for transporting greenhouse materials, it can load 5 to 10 greenhouses, and no tie down is needed.

In the last two picture, the trailer was loaded with one greenhouse, the 26 foot long U-Haul truck was unloading materials for 5 greenhouses.

Frequently Asked Questions

What is included in the Gothic 30x100x11 greenhouse kit?

The complete galvanized steel framework for a 30 ft wide x 100 ft long x 11 ft tall gothic-arch house: 30x55mm oval hoops, ground posts, purlin pipes, hoop-to-purlin connectors, roll-up sidewall hardware, end-wall framing, and entrance doors. Covering and ventilation equipment are optional add-ons listed on this page.

Why choose a gothic style greenhouse?

The pointed-arch gothic shape sheds snow instead of letting it pile up, and stands up to high wind better than round-arch houses. If your site gets real winter weather, look at gothic first — the shape does structural work that steel alone cannot.

Can I install this greenhouse kit myself?

Yes. The kit is designed for assembly with common tools, and many buyers build it with their own crew. Our professional installation team is also available at a discounted price.

How is the kit delivered?

Greenhouse kits ship on our own dedicated truck straight to your site. This kit weighs about 1,500 lbs; for pickup bring an 18 ft trailer (16 ft minimum) or a 26 ft U-Haul box truck, and have a level pad with truck access ready.

Does this greenhouse qualify for USDA NRCS high tunnel grants?

Yes. This kit fits the high tunnel design covered by the USDA NRCS high tunnel initiative under EQIP, which provides cost-share assistance to agricultural producers. We provide the quotes and specifications growers need for the application. Call Henry at (630) 408-2201.
