Give Your Plants a Boost with the Best Mini Greenhouse

Having a greenhouse is a welcome addition for many backyard gardeners. Starting plants from seeds can be a rewarding and cost-effective way to get a jump start on all your summer planting. After looking closely at the market, we have found that the Gardman R687 4-Tier Mini Greenhouse is the best mini greenhouse around.

It is roomy enough for all of your plants, but won’t take up a lot of space in your yard, patio or deck. The clear plastic cover allows you to view all your plants without opening the door. It includes a really nice anchor system to protect it against the wind (a huge bonus), and replacement covers are easy to get. For a full review of the Gardman R687, see below.

If the Gardman just isn’t your cup of compost tea, we would suggest you check out the Blissun 4-Tier Mini Greenhouse. This mini greenhouse is a solid best-seller on Amazon, and that’s always a good sign! We liked this one because the polyethylene cover fits like a glove, making the door easy to zip. It’s also a breeze to assemble, taking as few as five minutes and no tools.

Mini Greenhouse Reviews

A greenhouse is a great way to extend the growing season, or to have a cozy place to overwinter plants you want for the following year. However, polycarbonate greenhouses are quite expensive, and even walk-in plastic ones can be pricey. If you don’t have a ton of money or a lot of space, a mini greenhouse could be the perfect solution. But, with so many options that all look and perform very similarly, it can be challenging to decide which one is the best choice. Today we’re going to be reviewing and comparing six mini greenhouses, and out of the those we’ll choose: the best choice, a runner-up, and a budget choice to take some of the guesswork out of deciding which one would most fit your needs. You may find that a garden irrigation system is a great pair to a mini greenhouse, and makes quick work of watering all your plants!

The Best Choice Products four tier mini greenhouse greenhouse consists of two parts: a frame made from powder-coated steel, and a polyethylene cover. It has a compact design yet provides plenty of room for pots and seedlings and comes in an attractive green color. The steel frame is powder coated, and is quite rust resistant. The Polyethylene cover provides heat and protection. While it is reasonably robust, it will likely degrade over time, especially if left out in the elements. The Best Choice Products 4 Tier Mini Greenhouse has four wire shelves that can be removed for larger plants if needed and features a roll-up zippered door in the front for easy access.

This mini greenhouse can be used inside or out and is easy to assemble—no tools required. The shelves aren’t attached but sit on top of crossbars. You can use zip ties (purchased separately) to secure the shelves, adding a great deal of stability. It also features a 60-day “no hassle” warranty, which is a help, but it’s not an earth-shattering warranty! On the negative side, as with all these mini greenhouses, it cannot hold up well in windy conditions. If you’re going to keep the Best Choice Products Greenhouse outside, it is recommended that you find some way to anchor it. The best ways to secure it is by attaching it to a building or fence or putting heavier items on the bottom. Even though it claims to be an “all season” greenhouse, you will extend the life by not leaving it outside in extreme weather conditions such as high heat (three-digit temps) or subzero temperatures.

2. GOJOOASIS 4-Tier Mini Portable Garden Greenhouse

The GOJOOASIS 4 Tier Mini Portable Greenhouse easily wins the top spot in our Strangest Name for a Greenhouse category. Fortunately, it’s not just an oddly named product – it’s also a really nice, inexpensive greenhouse! Offering portability due to four included casters, this greenhouse is great for those who want to move their plants around throughout the day, or throughout the season.

Key Points at a Glance

• Shelves can hold up to 24 lbs.
• Made with powder-coated metal to resist rusting and a reinforced polyethylene cover
• Easy assembly without the need for tools
• Zippered front door allows easy access to plants

Weight11.5 lbs.

As with the previously reviewed greenhouse, the GOJOOASIS mini greenhouse is a pleasing and earthy green color, and is virtually identical in size. But because of the inexpensive cost and nice feature set, comparatively, we picked this greenhouse as our Best Budget Choice. With plenty of room on the shelves for your seedlings and pots, and the added security of knowing the weight limit of the shelves, this is a good choice for the backyard gardener on a budget. And we love that it has casters, so you can move it around! The GOJOOASIS features the same zippered front door common to virtually all mini greenhouses, and offers easy access to plants. It can be used inside or outside. As with the first greenhouse on our list, it’s important to note that if you plan to use it outside, it’s best to anchor it by securing it to another structure or using heavier objects on the bottom shelf. And it bears repeating—zip ties are your friends! We especially like these 8“ zip ties from Sunshades Depot.

The Ogrow Ultra Deluxe 4 Tier Mini Greenhouse features a very similar design to many of the other units on our list, and while it is a solid option, there’s nothing particularly Ultra Deluxe about it.
