    Ask a Question
    • 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 byoust@bootstrapfarmer.com 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: https://www.homedepot.com/p/ShelterLogic-30-in-Earth-Anchors-Set-4-Piece-10075/202719050 .  Its a realtively cheap anchor kit for added safety. 

    • Why would you need a hoop bender?

      Our DIY kit requires you to purchase the pipe locally (like Home Depot or Lowe's) and bend it into hoops. You can view our DIY kits here: https://www.bootstrapfarmer.com/collections/diy-hoop-house-kits

    • Do you have a 16’ wide kit?

      We don't currently offer a 16' wide DIY kit.

    • How tall is the center

      The center is approximately 8 feet.

    • Could I purchase more middle supports for my hoop house? Just to be extra safe one just doesn't look like enough.

      We have the purlin upgrade kit here: https://www.bootstrapfarmer.com/products/purlin-upgrade-set?_pos=1&_psq=purlin&_ss=e&_v=1.0

    • How much snow load will these 12’ wide houses handle?

      Because there are parts of a DIY build that we cannot control, the strength is variable. If you are dealing with snow loads and high winds I would recommend going with one of our All-Metal Kits. Or, you could consider adding a purlin kit and corner wind bracing to the DIY kit. 

    • 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: https://www.bootstrapfarmer.com/pages/greenhouse-kits

      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: https://www.bootstrapfarmer.com/products/air-inflation-kit?_pos=1&_sid=a982954d7&_ss=r

    • 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.

    • My beds are terraced on an incline of about 20%, could this kit be built across multiple terrace levels without being structurally unsound?

      No, it cannot be built on a terraced area.

    • Could I use a 4x4 pressure wood posts for the base?

      We recommend untreated wood for pieces that come in contact with the ground because of possible leaching of chemicals. 4x4 is also a lot wider than what you need. We recommend 1" x 8" x 8' ledger board for base board.

    • I am looking to build the 12x20 kit for my first greenhouse, but I'm nervous about wind. What is the wind rating for the DIY kits?

      Our round all metal kits have a wind rating of 115mph. Our gothic and DIY kits are not wind certified.
