There are many benefits to polyfilm greenhouses. One thing is that some municipalities will consider this a temporary structure and will not require permits, wind and snow load ratings, etc. They are also less expensive than a rigid polycarbonate covered greenhouse. One disadvantage to this is that most of the greenhouse polyfilm found today has a 4 year UV protection, so you will have to figure on replacing the covering every so often. Double polyfilm greenhouses consist of 2 layers of polyfilm with an air inflation system for greenhouse film blowing air between the 2 layers. This will give you a much better R rating than just a single layer of film. Manufacturers claim that it can save you up to 40% of your energy costs. That is quite a considerable savings. I find that the inflated film is more rigid and less susceptible to damage than a single layer of film. This all happens without lowering the light transmission properties of the polyfilm. This is an excellent choice that has been used by many commercial growers through the years and is totally acceptable for a backyard greenhouse operation. Be sure to use greenhouse polyfilm that is UV protected and has an anti condensate coating on it. If the film is not UV protected you should not expect to get any more than one years use out of it, sometimes even less. The anti condensate coating keeps droplets from forming on the film. This will contribute to the overall health of your plants. Any condensation that does form on the roof will come off in sheets rather than in droplets. If you have water dripping on your plants you will have damage to your leaves, fruits, flowers and overall less healthy plants. So, when considering your first or next greenhouse, take a look at a double polyfilm greenhouse and see what benefits it will give you.
With the long holiday weekend upon us, there is not a better time to visit a local display greenhouse. I have several favorites. I love to go to Bellingrath Gardens in Alabama. They have a beautiful conservatory. City gardens in New Orleans also has an excellent conservatory. Even the small town of Monroe, LA has the Biedenharn with a beautiful conservatory. If you have a little more time and can take a trip the Biltmore in NC will also take your breath away. Also, Calloway Gardens in GA has a conservatory with butterflies and plants. These are all probably within an 8 hour drive of our location. You will probably not have to go far to find several in your area as well. Take a young gardener along and inspire them. You will find many styles and sizes of conservatories and greenhouses to explore. This article is about a couple of photographers who have started on a quest to explore greenhouses in far away places. I am totally envious of them.
Magnus Edmondson and India Hobson’s greenhouse quest began in Oxford, England, at the Botanic Garden, on a Sunday morning. “We were the only people there, and it was so incredibly quiet,” they write. The only sounds were “gasps of wonderment” and the “occasional sigh.” From there, Edmondson and Hobson, photographers based in Sheffield, were hooked. They began what they call “a self-initiated Greenhouse Tour of the World”—they find, explore, and photograph greenhouses, potting sheds, polytunnels, conservatories, and other indoor spaces made by humans, for plants.
You have dreamed for years about owning a greenhouse. Now the time has come. What size do you get? Most people have problems making this decision. I think the best way to start is to think about how you are going to use the greenhouse. If you have plants that you are going to overwinter, I suggest laying them out in your yard in a configuration similar to what you will do in your greenhouse. Then you just measure outside the plants and voila, you have the answer to this question. If you are growing in raised beds, decide what size beds you will have and draw them out on a piece of paper allowing for adequate walkways. The same would apply if you are using systems such as hydroponic systems. Find out their size and draw them in a configuration you like on a piece of paper. When considering raised beds and/or greenhouse staging, you need to be sure that they are not so wide that you are unable to maintain the outside plants properly. I suggest not using any wider than a 3′ bench for benching that will be against a wall. If you are using a bench in the center aisle, it is OK to use a 4′ wide bench. Keep in mind that most of us will be comfortable with a 3′ wide walkway, so be sure to draw them in as well. I do not recommend even trying to put a center bench in a 12′ greenhouse. Lots of people try and I don’t think they are too happy with the outcome. If I would do this, I would only use 2′ wide benches to ensure adequate walkways. I would get at least a 16′ width for a center bench. The best thing to remember is that we are all collectors. You know, that perfect color plant, an unusual vegetable, etc. Don’t buy a greenhouse you will be crammed into with your current plants. Always allow a little room for expansion. If you need any help with this decision, feel free to contact us at Advance Greenhouses.
The same thing happens every year about this time. We are all still enjoying the warm weather of summer, getting the kids ready for school, and we forget about our beloved plants. I can’t tell you how many times in the past that Tom and I were installing greenhouses in the cold of the winter because they didn’t get ordered in time. Typically a greenhouse that is manufactured for you will take from 4 – 6 weeks for delivery. In the fall these lead times become extended, causing delays from the expected delivery times. This not only applies to greenhouses, it applies to polycarbonate sheets as well. They are typically delivered in 1 – 2 weeks, but in the fall they will take a week or sometimes longer past these times. So, even though it is really hard to think about it right now, if you are considering purchasing or building a greenhouse this fall, now is the time to start your decision process and get an order placed. Trust me, this I know from years of experience.
Yep, That is Tom and my greenhouse. We really do practice what we preach. We think everyone in America should own a greenhouse! This was a rare snow storm in SE Louisiana. I don’t think the neighbors could even believe that we were outside in this mess. Today I just wanted to take a minute to reflect on the beginning and growth of Advance Greenhouses. Fifteen years ago Tom and I were studying how to get on the internet. We knew the product we were interested in, as we had been selling and installing greenhouses for a while. Our first adventure with polycarbonate was in 1993. We got a book about 4 inches thick on how to set up a website and dove into it. What in the world language were those people using? Something I had never heard of before. I am sure we fought and cussed our way through it and came up with what was an absolutely horrible website. But, people started to find us. We also did a lot of local garden shows to put the word out. Fifteen years later, here we are. Through the years we have had the pleasure of speaking and working with many like minded people. We love flowers, but we also love fresh food that we have grown for ourselves. Our greenhouse has been multi faceted. We have stored my cherished hibiscus plants, started seeds for the garden, started annuals and perennials for the flower gardens and even grown some food hydroponically in our greenhouse. As I tell people, it is a learning curve to figure out exactly what will work in your greenhouse. There are some hard, fast rules, but we are all growing different plants under different circumstances. We all have to do a little bit of experimenting to figure out what works exactly for us. In closing, we are running some sales this month as a customer appreciation (also an appreciation for what we have thanks to all of you). Visit our website to see the specials. Our business is very personal and very rewarding for both of us. Thank You! Tammy and Tom
Are you wishing for a lean to style greenhouse as above, but own a ranch style home? You may have 8′ or 9′ attaching height for the back wall, possibly a little bit more. Do you think it is impossible to get a greenhouse attached to your home? Not so. There are 2 different ways we are able to fit these with our Acadian and Evangeline Lean To Greenhouses.
Lower Roof Pitch
For our standard roof pitch you have a rise of about 5 inches for every foot that you project away from the house. With our lower roof pitch, we can drop that to about 2 1/2 inches drop for every foot. So, for a greenhouse that projects approximately 10 feet, that would drop your attaching height about 25 inches. That is quite a considerable amount and will accommodate a whole lot of houses.
Fascia Attached Greenhouse
Still don’t have enough height with our Lower Roof Pitch? We are also able to offer a fascia attached greenhouse. This greenhouse will attach directly onto the fascia of your home, rather than the wall of your home. This will gain quite a bit of extra height, as you need to leave at least a 4″ clearance when you go under the soffit. This is so your roof vents can function properly. Combine this with our lower pitch, and you can attach this greenhouse to just about any home as long as you are not trying to project away from the home too far. If you will notice in the picture we also supply what we call an under soffit fill to fill in from the back of the greenhouse to your home.
In conclusion, just because you have a ranch style home does not mean you have to give up on owning a lean to greenhouse. We are more than happy to help you design the greenhouse of your dreams.
