Gardman R687 4-Tier Mini Greenhouse

If you are looking for something small, simple, and affordable, the Gardman R687 4-Tier Mini Greenhouse could be suitable for you.

This unit measures 27″ L x 18″ W x 63″ H, which means that it is not very large, but this small size means that it is ideal for tight spaces, such as small decks, patios, and even indoor sunrooms.

The fact that it is relatively small and lightweight makes it quite convenient in terms of portability.

This greenhouse comes with four tiers, each having slightly over a foot of height to work with, making this greenhouse ideal for small flowers and starting plants, such as growing seedlings until they reach a certain height.

The push-fit tubular steel frame is relatively easy to assemble, and as long as you don’t knock it over or place it somewhere windy, it should be fine.

The polyethylene cover and roll-up zippered door help keep plants warm and moist while also providing you with easy access.

Ideal for starters and seedlings.Not the most stable or durable item.
Easy access.Not very large.
Easy setup.

Quictent Cloche Mini Greenhouse

This is called a mini-greenhouse, and it’s not a full-size unit, but that said, it is also much larger than the one we just looked at.

The Quictent Cloche Mini Greenhouse’s dimensions are 71″ WX 36″ D X 36″ H.

It does not have any tiers; it’s just one large and open greenhouse, which means that you can fit large plants up to about 2.5 feet in height.

This unit weighs just 7 lbs. Assembling the lightweight metal frame is about as easy as it gets, which is why this greenhouse is also advertised as portable.

It’s not the most durable item, but it should be fine as long as you are relatively careful with it.

The Quictent Cloche Mini Greenhouse features an overlong transparent PE cover that helps magnify sunlight, retain heat and moisture, and keep harsh winds and temperatures at bay.

It’s nothing overly special, but it gets the job done.

Lightweight and portable.Frame could be more durable.
Large enough for some decent size plants.Could be a little more stable.
Good cover for plant growth.

Exaco RIGA III s 81 Greenhouse

If you want a real greenhouse with plenty of space and solid windows, the Exaco RIGA III s 81 Greenhouse is something to look into.

If it’s a big greenhouse that you want, something that can handle starters, full-size plants, and small fruit trees, this 81-square-foot greenhouse could be ideal for you, with dimensions of 126 x 92 x 87 inches.

You will need to have plenty of space for this greenhouse, but if you want a proper greenhouse, this is the way to go.

Unlike the other greenhouses we have reviewed, this one has polycarbonate windows or solid plastic, not just plastic film; they aren’t made of real glass that can break if you aren’t careful.

However, the Exaco RIGA III s 81 Greenhouse is ideal for plant growth.

It features an insulation R-value of 1.8; the windows are great at amplifying sunlight, retaining moisture, and keeping the weather where it belongs outside.

Sturdy and durable.Expensive.
Very large with plenty of space.Difficult to assemble.
Excellent insulation.

Palram HG6005 Oasis Greenhouse

This is our largest, most expensive, and most beautiful greenhouse.

If you want something professional and have a few thousand dollars to spend, the Palram HG6005 Oasis Greenhouse is well worth the investment.

This greenhouse is hexagonal in shape and measures 144 x 124 x 114 inches, making it massive for a backyard greenhouse.

Although you will need plenty of space for it, the Palram HG6005 Oasis Greenhouse can house many plants, and very tall ones too, even small trees.

The whole greenhouse features polycarbonate panels that let almost 100% of light and UV rays through. Your plants will get as much light as possible, and the windows go all the way around.

You get two louver windows for some added ventilation and viewing capabilities.

The heavy-duty anthracite powder-coated aluminum frame is solid, it can handle some bumps, and wind should not be a problem.

All in all, whether we are talking about spaciousness, beauty, durability, or functionality, this could very well be the best greenhouse out there.

Lots of UV penetration.Super expensive.
Large, hinged doors for accessibility.Assembly is a long and challenging process.

Walk-in Greenhouse

This spacious walk-in greenhouse lets you get a head start on planting season.

Constructed with a tubular steel frame and heavy-duty clear cover, this portable greenhouse also features roomy side shelves to store and monitor your new plantings.

The Walk-in Greenhouse is 57” Wide x 29” Deep x 76” High. The center is free of shelves, so you can walk into it if needed, or you could put some small trees in the rear.

The right and left sides feature three shelves, so you can put smaller plants and seedlings on them. It may not be a huge greenhouse, but it also doesn’t take up too much space.

This greenhouse features a heavy-duty powder-coated steel frame, so it should be durable and stable enough to handle a bit of punishment; however, it is not very heavy, so it won’t handle strong winds very well.

The reinforced clear polyethylene plastic is exceptionally durable and prevents heat and moisture dissipation, plus it keeps wind and rain out.

Good moderate size.Limited wind resistance.
Easy assembly.Shelves cannot handle all that much weight.
Durable considering the price.

Buyer’s Guide

Before you buy a backyard greenhouse, there are a few things that you should consider.

Types of Greenhouses

There are three main types of greenhouse designs that you should be familiar with.

Before shopping, do some research on the difference between attached or lean-to, freestanding, ridge-furrow, or gutter-connected greenhouses.

Temperature and Microclimate Considerations

Always consider how well the greenhouse is insulated, how well it keeps moisture and heat in, how much sunlight and UV the walls/panels can let through, and what sort of ventilation capabilities the greenhouse has.

Remember, your plants will need specific temperature, humidity, and light levels to flourish.


You also want to consider the price. You can find decent greenhouses for reasonable prices. However, you get what you pay for, so going for the cheapest option is not recommended.


If you are not constrained by a tight budget, and you really want the best of the best, the Palram HG6005 Oasis Greenhouse is what you want.

Yes, it is costly, but it is also huge; it’s ideal for all sorts of plants, and its features are better than most of, if not all, our alternatives.
