Best Hoop House Greenhouse Kits: Buyer’s Guide

Whatever the desired length, height, or breadth, your hoop house greenhouse must include a few essential components. These elements or features make these greenhouses perfect for placement in the backyard. As a result, we have included a list of some of those basic features that will serve as your buying guide for hoop house greenhouses.

Before we delve deep, let us remind you that there is no best or worst greenhouse option. Everything will be based on your needs, free space, local weather, etc. Therefore, look for the “right greenhouse” for you rather than the “best greenhouse.”

The Hardware

Not every kit is made equally. Therefore, it’s imperative that you do your homework on the hardware that comes with the hoop greenhouse kit that you intend to purchase. As an illustration, some kits include the hip boards and baseboards, while others need you to purchase them locally.

So, consider which one will work best for you and make your selection. However, we advise selecting a kit with all the essential and fundamental hardware components, such as nuts, screws, bolts, washers, etc.

The Gauge of the Hoops

The hoop thickness is a consideration that we frequently forget to count in. The hoops’ strength is evident from the metal gauge used to construct them. All gardeners are advised to use hoops constructed of 16 gauge galvanized steel. Additionally, picking hoops with a water-resistant coating would be fantastic. Remember that lighter gauge metals will be less expensive; they won’t be as durable.

Additional Information

Make sure to confirm that any greenhouse kit offers you all the alternatives you need before purchasing it. Many brands will offer you thorough information to make the best buying choice. Therefore, research the item, the kit’s components, and the local hardware requirements. Consider the price and accessibility of any locally acquired items as well. There is nothing worse than missing nuts and bolts keeping up an entire construction project.

Additional Items

Always check if your chosen hoop house greenhouse kit includes anything extra outside the essential hardware. For example, insect netting, landscape fabric, ventilation, shade cloth, etc., are offered by some brands. Check for these goods based on your needs. Nevertheless, you might save money overall if you purchase a greenhouse kit with extra materials, you’ll need rather than purchasing separately.

Size

A greenhouse that doesn’t fit in your yard is not something you would desire. In order to avoid this, make sure that your yard or the area where you plan to build the hoop house greenhouse is big enough to hold the product once it is set up.

Installation

Last, you should consider how long it will take to install the hoop house greenhouse kit. A product’s description will not include the labor required to assemble it. Therefore, you should still do the math yourself. Despite this, some brands will offer to construct support or solutions or at the least provide you with an estimate of the number of labor hours necessary. However, how much time you will need to install your greenhouse will also rely on your level of expertise and the number of helpers you have.

FAQs

Is a hoop house greenhouse worth it?

Yes, hoop houses are worth it. The use you intend for them will, however, determine their value. Nevertheless, a hoop house is the best choice if you want more control over plant growth. In addition, hoop houses are mobile, strong, and perfect for extending your growing season.

Can you use a hoop house in summer?

Yes, hoop houses are ideal to be used during the summer months. A hoop house acts as a mini greenhouse without a glass covering. Instead, the heavy plastic sheet for greenhouse does the work here. To keep insects off your plants, cover them with blankets or fabric. Additionally, during sweltering summer days, shade covers can shield your plants.

Why is everything not always included in a hoop house?

The explanation is straightforward: You might not always need the extra items. Various farmers use hoop houses for various purposes. Most brands offer hoop house kits with all the basic hardware. Whether you require any accessories will depend on how you customize the kit. Therefore, you would have to purchase them locally.

What are the differences between a hoop house and a greenhouse?

Two key factors distinguish a greenhouse and a hoop house.

A hoop house is taller than a greenhouse and has higher pillars. The second distinction is that whereas a greenhouse regulates heat artificially with machinery, a hoop house does it naturally using doors and windows.

Can I start seeds in a hoop house?

Yes, seeds can be started in a hoop house.

Conclusion

The article’s key takeaway is that hoop homes are an excellent option for extending your plants’ growing season. And based on our study, one of the finest hoop houses available is the 20-foot wide Bootstrap Farmer hoop house kit. It would be best to get this affordable tunnel kit if you have a large yard. On the other hand, if you have a modest yard, choose the 12-foot wide hoop house version from the same brand.
