If you’re a serious gardener, and you have the space, then you might consider getting a backyard greenhouse kit set up. A greenhouse provides an ideal, stable, warm environment for year round growing. Depending on the size of the greenhouse, you can continue to grow plants inside it year round, until they reach maturity and are ready to be harvested, and/or simply use it to start seeds, or to protect younger plants until they’re ready to be moved out into the garden.
Having your own greenhouse also allows you to explore growing vegetables and plants that aren’t ideally suited to your growing climate, usually due to frosts and cooler weather. In addition, plants like tomatoes and peppers ideally prefer the climates inside greenhouses and fruit will ripen faster and usually produce larger yields.
There are many different options when it comes to setting up your own outdoor greenhouse, from the DIY approach to having a professional builder build you one. However, if you would prefer an easier and/or less costly solution, then you might want to consider a kitset that comes ready to assemble. Here are a few kitset ideas that you might like to consider…
The Palram Hybrid Hobby Greenhouse Kit is a smaller to medium sized outdoor greenhouse coming in at 6′ x 8′ however in total it provides 48 square feet of indoor growing space. The framing is made from rust resistant aluminium and it also has a very heavy-duty galvanized steel base to give it more support.
The walls and roof panels are made from a very strong clear 4 mm twin-wall polycarbonate, allowing for ample light inside the greenhouse whilst blocking up to 99.9% of UV rays. These panels are designed to diffuse the sun light entering the greenhouse to help eliminate the risk of plant burn and to also help light reach plants that are partially shaded.
The greenhouse also includes other very useful features such as adjustable roof vents to allow for more controlled ventilation. The roof also includes rain gutters to help with water run off. It also has a lockable door handle on the door with a magnetic door catch.
The kitset also comes with 10 polypropylene plant hangers which can be hung inside to support vine crops or to hang plants from. The greenhouse comes with a 5 year limited warranty and has USA based customer support. As previous customers have said…
“In a word, awesome. When you first see this product it looks difficult to assemble and the lack of specific directions on some of the pictures can lead to confusion but once it’s done it’s sturdy, large, spacious and well put together. Took about four hours for two of us. Don’t forget the anchor for peace of mind on windy days…”
“This greenhouse has been very productive for me. I grew lettuce in early spring in Ohio, then was able to start my seedlings early. I have been able to grow tomatoes and peppers in the greenhouse even in the hot summer days with the top of the door and vent open. The side attachments are very sturdy and have handled weight well…”
The Royal Victorian Greenhouse provides 150 square feet of growing space and is considered one of the premier kitset greenhouse options on the market (quality made by Janssens of Belgium). It is certainly a decent investment given the price, however if you’re looking for an extremely robust and well built option that will stand everything the weather can throw at it, as one customer put it “(this is) a Greenhouse that can outlive your house. It’s that good”.
The greenhouse itself measures 10’2″ wide x 15′ long x 9′ high, providing 150 square feet of total growing space inside. It also includes 4 roof windows that can be independently opened to allow for ventilation (two located on each side of the roof). These roof windows come with both an old fashion spindle mechanism to manually open them, and also a modern automatic window opener.
The frame of the greenhouse is made from large thick aluminium and also has a built in watering / misting system to water the plants inside. You simply attach a hose to the respective faucet on the greenhouse and away you go. This is a true “glasshouse”, with all vertical panels being made from a single piece of glass, and windows are held in place by substantial rubber seals, which provide for better insulation.
Given its design, the sliding door to access the greenhouse can also be placed in any vertical location – front, back, or sides – depending on what you would prefer. This is a Rolls Royce kitset greenhouse and if you’re not up to putting it together yourself, there is also an installation service available. As previous customers have said…
“We are so pleased with this greenhouse. I did extensive research during the decision making process as this is a sizable investment. We installed it at the end of summer 2015. I love the automatic vents, very helpful as the day heats up. The structure has survived hail, wind and heavy rain without leaks. We grew tomatoes all winter inside. We have customized it to fit our needs. We’ve added concrete block/brick floor, shelving we owned previously, micro watering system, and electrical. I definitely made the right decision…”
“We have had our Greenhouse for over 10 years now. That’s correct over 10 years and it still looks exactly like it did when we bought it. It hasn’t faded or broken in any way. The automatic openers still open perfectly as well as all doors and manual skylights. We bought it as a sunroom mostly and moved on to plants and entertaining guests in it…”
The Rion Grand Gardener Clear Greenhouse is 8′ by 12′ (although the length can be increased up to 20′) making a very nicely sized outdoor greenhouse. Unlike other kitset options, the framing on the Rion Grand is actually made from a heavy duty resin to help improve insulation and to give it extra durability (and also keep costs down).
The wall and roof panels are made from 4 mm thick twin-wall polycarbonate which are 100% UV protected and are resistant to high impacts. They also diffuse over 90% of the incoming sunlight for a soft even light and to help protect the plants inside.
The frame also features simplified assembly using a pin and lock system, and the roof panels simply slide into place. The barn style roof design provides ample headroom and gives you more space to garden. Double doors into the greenhouse allow for easy access and also help to provide ventilation, and an included roof vent provides a heat vent even when the doors are closed.
It is recommended that you secure this greenhouse to a concrete pad or heavy timber foundation for extra strength and security. As previous customers have said…
“Very durable product! Was able to put this together fairly easily… mind you, it was difficult in some areas… but considering what you are trying to accomplish here, it was to be expected. As long as you follow the directions precisely and make sure you keep everything square and level, you should have minimal to no problems constructing this greenhouse…”
“Overall, I am pleased with the greenhouse. And it’s going to provide several years of growing pleasure in my backyard. It’s a quality product that seems very well thought out and implemented…”
The Palram Bella Hobby Greenhouse is 8′ x 12′ and provides 96 square feet of growing space. Its roof and walls are made of 6 mm twin-wall polycarbonate panels that block up to 99.9% of UV rays and help to create an even-light and maintain ideal temperatures.
The rust resistant frame is made from aluminum and the unique bell shaped roof design provides 7′ of head room at its peak, which also helps to decrease wind resistance and reduce snow build-up.
The greenhouse also includes an adjustable roof vent for adequate ventilation, a lockable door handle and galvanized steel base for greater structural support. It also comes with a 5 year limited warranty and US based customer support. As previous customers have said…
“I love this greenhouse, with the recent cold weather not usual for the south it has provided ultimate protection in keeping my plants safe. Highly recommend this product…”
“I looked through a large number of greenhouses before I bought this one, and most of them scared me off because the reviews went on and on about how hard they were to put together. I can’t say this one was easy to construct because it has about a million pieces, but the instructions were very clear and nothing was really difficult to do, it just took a lot of time…”
