2021 Review – Backyard Greenhouse Kits from Greenhouse Emporium

What is a Greenhouse Kit?

It’s a ready-to-assemble backyard greenhouse kit. The kit comes with all the necessary parts in order for the owner to assemble the greenhouse. There are lots of different sizes, styles and prices ranges.

The backyard greenhouse kit or some people call them hobby greenhouse kits, are well-built, warm atmosphere for the plant to be grown all year. In the cold climates a greenhouse heater or solar heater would be needed to use this garden all year around. Having a greenhouse is a valuable investment. It’s a great way to produce crops and fresh plants in the garden no matter the season or weather. Having a greenhouse can be enjoyed for many years.  I will review why you should or shouldn’t purchase a greenhouse from Greenhouse Emporium.

Now that greenhouses are made with modern materials, it has become more affordable and increase the lifespan of a state-of-the-art greenhouse. Having a hobby greenhouse are becoming a thing.

Important things to think about before buying a hobby greenhouse

Before purchasing a greenhouse kit, you need to make sure which greenhouses will work in your region, like if you get heavy snow. It is recommended to buy a kit that is strong and heavy-duty. If you plan on using the greenhouse all year around, with the winter months, it will be essential to get an insulated framing and insulated greenhouse covering material to help keep the warmth.

In the desert type areas, the greenhouse will need shade, water and plenty of ventilation. Consider the quality of the frame and accessories that come with it.

Types of Greenhouses

Cold Greenhouses or Cold frames – these types are limited by the weather, These are used for starting seeds early and extending the growing season.

Cool Greenhouses – are greenhouses that stay above freezing between 40 and 50 degrees. This works for plant that are not winter-proof, like geraniums or hyacinth.

Warm Greenhouses – stay at a warm temperature of 50 to 55 degrees. These will help protect flowers that are sensitive to cold temperatures. The flowers that will benefit in this greenhouse are roses, chrysanthemums and orchids.

Hot Greenhouses or Hothouses – these greenhouses or sometimes called hothouses have temperatures of 60 degrees and above. Perfect for tropical plants.

Freestanding Greenhouses

This is a stand-alone greenhouse that allows you to set them up where you want as long as the spot has plenty of daylight and the greenhouse will be level on the ground. Greenhouse Emporium offers a wide variety of frame structures that are freestanding, for example; conventional greenhouses, arch-shaped, geodesic domes and others.  I have reviewed a few freestanding greenhouses.  I put them in order of less expensive to expensive.  There are many options of greenhouses at the Greenhouse Emporium.  I encourage you to look at all them to see what is the best one for you.

  1. Good day, I’m pleased to come across this important information. I’m thrilled to know about backyard greenhouse kit, which I didn’t know much about. The outlined benefits of having backyard greenhouse are just awesome. I like the concept of controlling the climate to suit the crops to grow, as some are mostly seasonal. This is a very helpful information.

  2. This is a great selection of greenhouse kits, together with some awesome tips as what to look out for and consider when choosing a kit. I do like it that so many of the kits now come with shatterproof glass and polycarbonate panels, as glass breaking during a storm can be a real hazard. 

    Do you think it will be better if the greenhouse is built on a solid base like concrete, or can we build it directly onto level soil?

    • Hi

      I love the greenhouse selection at Greenhouse Emporium.  I am hoping to get one within the next couple years or an addon sunroom to the house.  As far as the base or floor, you can do either way.  With no concrete you could plant in the ground in the greenhouse.  Thank you for your comments

  3. We currently have a DIY greenhouse, which, due to weather problems (we have had stronger winds over the last few years), needs to be repaired regularly.
    If my finances allowed, it would be difficult to decide which of the above and described I would buy, because these larger ones look very spacious and high quality.
    However, these smaller ones are also attractive and affordable for a more reasonable price. Mostly in our greenhouse, we grow seedlings of flowers and vegetables, which we then transplant to the garden, so smaller ones are also suitable for my needs.
    Thank you for presenting the great offer of Greenhouse Kits from Greenhouse Emporium.
    Friendly greeting,
    Nina
