  • How can i apply(pay) for 100' greenhouse

    You can just select from the drop down to the left of the add to cart button and select the 100' option.  Then just add to cart and checkout.  You can reach us directly at 1-252-495-6088 or if you need any additional help or have any questions.

  • I live on top of a hill. No wind block. Will this house withstand Oklahoma wind? How much is current price of replacement Covering? How much for everything except 2x4's , Lumber?

    This can withstand high winds.  We live on the coast of North Carolina so are subject to high winds ourselves.  However very high wind areas we may recommend some extra anchoring using the following anchor kit: .  Its a realtively cheap anchor kit for added safety. 

  • Can I get a step by step instruction manual, using your materials, that I can study to be sure I am comfortable erecting this on my own? How many people are usually necessary to build this project? How long does it take?

    It can be put together for the most part by one person but there are a few steps, like putting on the plastic, that are far easier and faster with extra hands. As for the time frame, it depends on your ability level, the length of the house you will be building, and your comfort with the tools required. However it can be constructed in a few days by 2 people. Generally 24-48 hours of working time. 
    All of our manuals are available for download on this page.

    We highly reccomend looking over the resources on this page and checking out our YouTube channel for videos of the build process.

  • Can I make it 15 feet high from center

    Yes you can make the structure taller by using taller ground posts. If you choose to do this please contact us before you order as we will need to modify the kit to include a wider piece of UVA plastic.

  • I am looking for a greenhouse that comes with fans and a heater for winter . Suggestions helpful! Thank you!

    Here is a link to the greenhouse kits we offer:

    We do not currently carry any fans or heaters but we do offer an inflation blower that is used with two layers of plastic, which can be found here:

  • 1x8x8s are now 15 dollars a piece. Can regular 2x4's be used in their place for hipboards and baseboards?

    Yes you can.  You'll just want to make sure longer screws are used.

  • I’ve seen hoopbenders that come with a stand to allow for top/down bending. I bought a 20’ bender from you guys. Do y’all make a stand I can order? Or just table top mounting ?

    We don't have a stand, but you can attach a board to a wall, and if you had a long screw, you can attach the bender to that.

  • Is tere an instruct video on putting on the second layer of plastic?

    Not currently, but you can do it in a similar way of the first layer.  A second layer of wiggle wire will fit in the channel. 

  • I am about ready to order a 12ft. X 40ft. high tunnel.I want to use 1 3/8 poles that are 21ft. long instead of the 2 10ft. hoop poles.Is there any reason I can not.

    I can't think of any reason that it shouldnt work.  

  • On a 12 ft. wide high tunnel, what will be my height at the center?

    Assuming you have ground posts that are 2' out of the ground your greenhouse wil be 8' hight at the center.
