But, how to pick the very best one for you and your gardening needs? Simple: Research, analysis, and personal preference.

Luckily, we have taken care of the first two parts of the equation for you by researching, comparing, reviewing, and presenting you with five of the best greenhouse kits on the market!

After browsing through our reviews and recommendations, take a look at the guide sections below for a full run-down on everything you need to know about greenhouse kits before investing in one.

Best Small Greenhouse Kit

The Home-Complete HC-4202 Walk-In Greenhouse is our top pick for a small greenhouse kit.

It is designed with heavy-duty polyurethane and works well all year, indoors and outdoor.

The kit includes eight shelves that allow space for plenty of plants, pots, and trays.

Assembly is super-fast and requires zero tools or experience.

All you have to do is read the directions and connect the rods to get started, slip the PVC cover over it, use the included rope and anchors to give it stability, and set your shelves up.


  • heavy duty design
  • includes plenty of shelves
  • works both indoors and outdoors


  • requires a bit of work to set up

Our Favorite Features

it is lightweight, easy to assemble, and built to fit small spaces. We also love that it is for indoor and outdoor use and comes with shelves.

Best Mini Greenhouse Kit

Our second pick is the Gardman R687 4-Tier Mini Greenhouse, one of the better mini greenhouse kits currently available online.

The greenhouse is made with seed-starting, transplants, and young plants in mind, but works for a wide variety of purposes.

This kit takes very little assembly time. Just push the tubular steel frame pieces together and slip the cover on. It comes with four shelves and features a roll-up and zipper door and is quick and easy to access.


  • heavy-duty steel frame
  • easy to put together
  • zipper door for quick access
  • includes four shelves


  • doesn’t offer as much room as a full walk-in

Our Favorite Features

The unit fits almost anywhere(even on patios and balconies), works great as a nursery or for growing micro-greens, and is extremely mobile.

Best Hoop Frame Greenhouse Kit

The NWSS Tunnel Hoop Greenhouse is our top pick for hoop-style greenhouse kits, and believe us, we looked at a boatload.

This kit is affordable enough that you could probably buy two or three of them if you want to make an extra-long greenhouse or “wind tunnel,” as well.

Each kit comes with six multi-function, eco-friendly, fiber-glass, grow tunnel hoops that work as plant support during the warmer months, and after adding a cover, it also works as a growing season extender during the fall and a full-out greenhouse in the winter.


  • eco-friendly tunnel design
  • looks good and works all year
  • easier to install than other greenhouses


  • aren’t as heavy-duty as other greenhouses

Our Favorite Features

Eco-friendly materials, dual-purpose(also works as a support for climbing plants), and the classic hoop-style design.

The 1-year warranty, and a separate money-back guarantee, are also nice.

Best Wooden Frame Greenhouse Kit

If it is a genuine DIY greenhouse that you are after, and one for the picture books at that, consider our fourth top pick; the EZ Shed 70187 Peak Style Instant Framing Kit.

This package comes with all the essential hardware(24 steel angles and 12 steel plates), to start building a classic cottage/shed-style greenhouse.

You will need tools for this build, and extra materials as well.

Timber and plastic or Plexiglas are not included with the purchase.

Again, this one is for those handy gardeners who know a thing or two about building and enjoy the fruit of their labors.


  • heavy duty design
  • includes plenty of space and is expandible
  • made for all-year use outdoors, even in winter


  • timber and Plexiglas must be purchased separately
  • requires more time and skill to put together

Our Favorite Features

We love the fact that there are three different building plans included.

We also love the fact that you can finish this greenhouse however you like(wrapping it in plastic, adding windows, or attaching Plexiglas – you can even add whatever sort of door you want).

What to Look for in a Greenhouse Kit

Now that we highlighted our top picks for the best greenhouse kits to consider investing in, let’s explore the most significant factors that you should think about before buying just any old kit.


First and foremost, size matters, a lot, despite what your wife told you.

Not only does the size o the greenhouse itself matters, but the size of your property, and more specifically the size of the area in that you plan to set up your kit.


The shape is another important factor, aesthetically and otherwise.

Depending how much room you have for a greenhouse, and the amount and type of plants you plan to grow inside of it are also crucial considerations to take into account.

Shed-like greenhouses offer room for taller plants, even trees. Rounded and gabled types tend to have lower ceilings.


The overall quality of a greenhouse is in part determined by the materials it is composed of.

Today, some of the best models consist of lightweight PVC frames and durable plastic sheets.

On the other hand, many high-end greenhouses are constructed from aluminum, wood, and even steel frames.


What you plan on doing with your greenhouse also matters quite a bit.

The best greenhouse for starting seeds and housing transplants, for example, is not the best for growing tomatoes or beans.

However, micro-greens and other crops that take up very little space and can be grown on shelving fit in practically any sort of greenhouse.


Your budget is most likely already set, and that is just fine.

In fact, most of us are working on strict budgets(or practically no budgets) when it comes to our backyard gardening.

An inexpensive kit may run you $50 or less, but it won’t house much more than seedlings and a few potted plants. Large, more extensive, and expensive greenhouses can run upwards of $1,000 or more.


If you are considering buying a kit that doesn’t come with a warranty – do not do it. It is not worth it when you can find another comparable unit for a similar price that comes with at least minimal coverage.

The best greenhouse kits include money-back guarantees and at least a 1-year warranty. Some kits even include 5-year, 10-year, or lifetime warranty options.

Frequently Asked Questions About Greenhouse Kits

Here are a few of the most frequently asked questions that we found about greenhouse kits.

Are greenhouse kits really worth it?

Only you can decide the answer to that question. How much will you benefit from a greenhouse?

Do you have the energy, and time, to put it to good use? Would you regret spending the money?

These additional questions may help you make a decision.

Do I need a kit to build a DIY greenhouse?

You absolutely do not need a kit to build a proper greenhouse.

Does a kit make it easier, quicker, and more professional-looking? In most cases, definitely so.

That said, with a plan, a stack full of materials, some tools, and a bit of dedication, anyone can build a greenhouse from scratch – no kit necessary.

Do greenhouse kits require tools/skills to assemble?

There is no black-and-white answer to this question.

There are just too many different kits out there. Some snap together, like puzzle pieces, or similar to how sheets of vinyl siding interlock with each other.

But, many of the highest-quality kits do indeed require the use of a tool or two.

And, while carpentry skills are not a requirement, it does help make the process easier.

How much does a greenhouse kit cost?

There is no real average cost for a greenhouse as there are so many various models on the market.

The smallest ones, mini and micro-sized kits, range in size from tabletop greenhouses for seedlings to units the size of a broom closet.

These kits cost between $25 to more than $200. Larger, normal-sized greenhouses the size of a shed, to models the size of small pole barn range well into the hundreds of dollars and on up into the low thousands.

Which Greenhouse Kit is Best for Your Yard or Garden?

The kits in this guide are far from the only ones available, or worth your investment for that matter. They are, however, our top recommendations. Regardless of what size or shape you want in your new greenhouse, one from our list should work for you.

That said our favorite pick by far is the Home-Complete HC-4202 Walk-In Greenhouse. It is as great for a first-time greenhouse as it is as an addition to anyone’s yard or garden.
