Purchasing a greenhouse can be a difficult and sometimes overwhelming process. The first factors you should consider are location, foundation and of course your budget. All foundations should be level and square. A square and level foundation will eliminate challenges later when installing your greenhouse. A raised foundation or knee wall is a good option if you prefer to add height to your greenhouse. Knee walls are commonly 12-48 inches high and can be made of various materials. If you would like a knee wall with your Sunglo greenhouse kit please notify us at 800-647-0606 to add a door drop kit to your order.
Concrete is a great option for a greenhouse foundation and often chosen among consumers because is it convenient. To attach your greenhouse to a concrete base we recommend attaching quality treated wood to the base of the greenhouse, commonly called a wood sill plate. 2 x 4’s will do. If you choose to use pressure treated wood make sure to install a barrier between the wood and aluminum, such as gasket material, as the treated wood can cause the aluminum to rust. Sunglo includes a barrier called a “boot” with each greenhouse kit.
Measure twice before cutting your wood to ensure proper dimensions. We suggest allowing a 1” border around the inside and outside of the entire greenhouse. Sunglo adds 2″ to each greenhouse size for the foundation measurements.
This is designed to allow a safe margin for irregularities in the wood sill plate. After the concrete has been poured and is level and square, a small drain should be placed in the center of the slab where water run off can drain into a gravel pit or piping that leads to a drainage area. Then your greenhouse can be bolted to the foundation. Water and electricity should be ran to the greenhouse site before the foundation is built.
Building a wood base is easy and inexpensive. Cedar and redwood are commonly used. Pressure treated wood is also a great option but make sure to put a barrier between the wood and aluminum, such as gasket material, as the treated wood can cause the aluminum to rust. The size of your base will depend on the size of your greenhouse again allowing a 1” border around the inside and outside of the greenhouse. After assembling the base and making sure your ground is level lay down a weed barrier. This allows the water to drain through but does not allow weeds to come up through the floor boards.
Pack the natural earth over the excess barrier. After your base is finished and the weed barrier is set underneath, you need to cover it. Start laying down your wood planks to make the floor. Now it’s time to attach the greenhouse frame to the base – Make sure it is level and square again by measuring from corner to corner. For added insulation, we suggest you caulk the bottom of the aluminum framing (caulk the wood then attach the frame – making sure there is a barrier between the aluminum and wood) where it meets the base with a waterproof sealant – If you are using pressure treated it is still a good idea to caulk between the base and wood. This will add extra protection to the greenhouse and keep cold air from entering and warm air from escaping in the colder months. If you are using pressure treated wood make sure the aluminum does not come into direct contact. Sunglo includes a plastic “boot” that attaches to the base rails with all our kits, so you don’t have to worry! As with all foundations please consider whether you will need water and electricity ran to the greenhouse site. Wood foundations are natural and beautiful looking! The only down side is you might have to replace the wood every 8-10 years.
If you are planning on purchasing a lean-to style greenhouse or even a small free-standing but only have room on your deck, that’s no problem! Before attaching the greenhouse base to pressure treated wood lay down a thick rubber, insulated mat that is the dimension of the floor of your greenhouse.
There are various mats you can purchase that have designs or just plain old black. Insulating underneath and around the base is a good idea also. To attach the greenhouse base to the deck we recommend contacting your hardware store representative and explaining the project. Decks are made of different materials and you wouldn’t want to ruin your deck in the process. Now insulation will be an issue as well. Depending on your style of deck please take this into consideration and do your research on what type of insulation, if any, you should use. Water and electricity can be easily ran to a greenhouse on a deck foundation as it is usually attached to a house or a building.
There is lots of info on the web about different foundations and step by step instructions on how to build them. I hope this gave you an idea of what you want to do with your foundation!
NOTE: If you choose to create a foundation that is NOT concrete we highly recommend giving the wood base a few days to settle. After 24 hours re-measure for square and level. In some cases the foundation will settle and become uneven affecting the assembly of the greenhouse. And you dont want that to happen because it can make installation very difficult!

Small cracks and loose glazing materials can cause unwanted air to enter or escape from your greenhouse. Obviously both will affect the efficiency of any heating system you have in place. But fixing areas around the doors and vents that are not air tight can help stop unwanted air flow. Caulking holes or lining parts of the frame and weather stripping around the door can make a big difference. Shutting your fans off during the winter and covering them with a thick plastic will help keep your greenhouse regulated in the winter months. And always fix any holes or broken panels as soon as possible. If you have a Sunglo you can call 1-800-647-0606 for any replacement parts!
Use a double layer glazing system –
Double layered glazing material can be beneficial, if it is done the correct way. Our greenhouses have an inner corrugated panel that creates a 1.5” dead air space keeping it exceptionally insulated. To see how Sunglo’s unique glazing system works click here.
Install windbreaks –
Windbreaks are important in high wind areas because it prevents the cold wind from hitting the greenhouse therefore cooling it down. Building a mini fence or even planting shrubbery around the base of your greenhouse is effective. Some gardener’s plant small trees around their greenhouse, it not only looks pretty but will help keep the wind at bay. Whatever you decide to use make sure it stands mid-level to your greenhouse so it doesn’t block the sun. If you already have some tree cover in your yard or near the greenhouse than your in luck! No planting for you!
Use a shade cloth –
Shade cloths are wonderful for high temperature areas. They are used during the hottest time of the day to reduce thermal solar radiation. Sunglo carries a wide variety of sizes and they can be mixed and matched to perfectly fit your greenhouse. For more information on shade cloths click here.
To calculate what type of heater you’ll need for your greenhouse there is a simple formula. Take the temperature you want the greenhouse to stay at (let’s say 50) and the average winter temperature in your area (how about 20) and subtract them (equals 30). Next you multiply the temperature difference by the surface area of your greenhouse (8×10 greenhouse is 276 X 30 = 8280). Now you multiply your answer by your greenhouse materials U value. For a Sunglo you would multiply 8280 X .75 = 6210 BTU’s(.75 is Sunglo’s U value). This means you need to find a heater that has exactly or over 6210 BTU’s to efficiently heat your greenhouse. Using the correct heater will ensure thriving plants and not use unwanted electricity. To see this formula again and more in depth information on BTU requirements check out this post. Click here.

Gardening is a valuable tool for children of all ages. Learning about plants, how things grow and how to nurture and care for living organisms. Caring for plants introduces
many other topics such as the role insects play and the importance of light, water and maintenance. Gardening has been known to also improves children’s environmental attitudes, their social skills and nutritional attitudes. The National Gardening Association has provided grant funding for the past 29 years to support youth garden programs. They have awarded over 9,000 grants throughout the years and provided beneficial education to our nation’s children. The benefits from school gardens reach everyone including the parents, teachers and administrators. To view a list of grants available and valuable resources visit this website.
Sunglo has been a proud resource for school greenhouses for many years. Providing a covered, safe area for children to learn about gardening and all the beautiful life lessons along with it.

There are many factors involved in greenhouse gardening. And we all know that to grow different plants and flowers the conditions need to be just right. So climate control and ventilation are very important. Greenhouses can get very hot in certain areas around the country. So for that extra protection we offer shade cloths.
But why? Well, in humid areas misting and fogging may not be adequate enough in thosehot summer months. And excess moisture build up can become a problem.
There are many different ways to “shade” your greenhouse. Spray on and liquid options are available. As well as woven polyester or even aluminum varieties. Shade cloths can be found in varying densities or degrees of shade from approximately 5% to 95%.
Sunglo offers a 73% gradient polypropylene cloth with double sewn reinforced hems and brass grommets for easy anchoring. Polypropylene is a thermoplastic polymer and it is used in a variety of products around the world.
Polypropylene is normally colored using carbon black. It is tough stuff but still flexible and it has good resistance to fatigue. It is suseptable to UV damage from sunlight exposure but our shade cloths are coated with a UV absorbing additive and carbon black also has some “SPF” properties to it.
Shade cloths can be the difference between beautiful plants or burnt plants! Don’t leave your plants to risk, shade cloths are inexpensive and will last you through the years keeping your plants safe and happy!
Please contact us to request our complete pricing and product catalog.
To attach Sunglo’s shade cloth to your greenhouse, use some bungee cord or rope to thread through the grommets and secure them to some loop posts that are anchored to the ground or base. Lean-to models: For convenience try to set up the loop posts so you can easily roll the shade cloth up or down.
Call or e-mail us for our shade cloth instruction diagram. Please specify free-standing or lean-to.
We are very happy to announce the grand opening of Seattle University’s new greenhouse facility! Their new 2100K model greenhouse will provide the Biology department with the space they desperately needed to conduct experiments and house plant specimens.
We are very thankful for this opportunity to provide many generations of budding plant physiologists with a space to further their skills and knowledge. The Norman Borlaugs and Gregor Mendels of future generations could very well be among them.
We greatly enjoyed working with everyone to make sure that this greenhouse fit the specific requirements of the department and its students. The end result is a fully ADA compliant facility with a modular floor plan that allows for multiple growing configurations.
We would also like to thank everyone who contributed the funding that made this project possible. If you are interested in discussing the many grants currently available or how your students could benefit from a similar facility please contact us anytime.
O’Malley and Jon Stoumen have a most amazing Sunglo greenhouse and urban garden. Every square foot of their property provides either a habitat for native species or what I imagine is quite a fresh bounty of naturally grown food. They recently participated in a tour of local gardens and were kind enough to send us these pictures. I was at a loss for words when looking at them, but beautiful and inspiring certainly come to mind.
We LOVE our sunglo greenhouse! We have a big vegetable garden and I started all the seeds in January under a grow light. Most of the stuff is planted out now so I am rooting sedum cuttings for a future green roof project. It fits in nicely next to our chicken coop and I am amazed how much time I spend in there. We are on a huge garden tour in the spring, April 26 & 27. It is the biggest one in Palo Alto and it will last for two days. The tour is the Gamble Garden tour and there will be a lot of people looking at our beautiful greenhouse. Thanks again for such a wonderful product.
Though the videos date themselves, the tests conducted in them are perhaps more relevant today than when they were originally filmed.
Our dual pane Therma-Truss® construction uses UV stabilized; impact resistant DR acrylic which resists discoloration and deterioration for up to 20 years. It incorporates a smooth outer layer and corrugated inner layer as shown in the diagram at right. Light is diffused evenly throughout the greenhouse by the corrugations while still allowing 92% of solar radiation to pass through.
This design is what started it all 35 years ago, and is what truly sets a Sunglo apart from all the rest today. In an industry overrun with flimsy, snap together polycarbonate greenhouses, you can take solace in knowing that somebody still considers American made quality to be more important than outsourcing overseas to improve the bottom line.
