This is an excellent article from our friends at Garden and Greenhouse magazine regarding the need for consistency in your greenhouse environment. In order to have the best, consistent growth it is important to have the best, consistent climate. Although I must say that I find this a little bit more on the advanced end of greenhouse growing. I do not suggest that someone jump in with every known greenhouse accessory when initially purchasing their greenhouse. I recommend getting a ventilation system, as it is an integral part of the building. You can retrofit them, but it is easier to install them when you are putting up your structure. A heater is also a good accessory to order with your greenhouse. As far as some of the other systems are involved, I suggest experimenting and finding out what you need rather than outlaying a bunch of money for accessories that your climate or plants may not need. Unless you are an experienced orchid grower, for example, you will know what humidity, etc your plants will need. Then it would be a wise decision to get your greenhouse set up with these systems at the beginning.
Consistency is the key to unlocking the maximum potential of an indoor garden or greenhouse. Plants thrive on consistency. Plants respond best to light energy, atmospheric conditions, and nutrients when they are kept as consistent as possible. Like people, plants burn sugars to provide energy for growth. In contrast to people, plants have the unique ability to create those sugars from sunlight. The creation and consumption of these sugars are actually part of a chemical equation. In other words, there are countless chemical reactions occurring at all times within and around the plant that contribute to healthy development.
When atmospheric conditions, lighting and nutrient levels are at optimal levels, the plant has everything it needs to make those chemical reactions happen without interruption. When the chemical reactions can occur without interruption, the plant’s growth rate is maximized. Maximizing the potential of a particular crop is the goal of just about every indoor horticulturist or greenhouse hobbyist. In order to maximize the potential of an indoor garden or hobby greenhouse, a horticulturist should closely monitor the consistency of the garden’s temperature, humidity, lighting and nutrient solution. Each of these factors has a significant effect on the chemical reactions that contribute to plant growth.
Even though this picture was taken several years ago, it won’t be long before many of us will be seeing this as we look out our windows and long for summer. I know it is a few months yet, but now is the perfect time to prepare your greenhouse for winter. It is still warm enough that you can move any plants remaining inside the greenhouse to the outdoors. This will allow you to give your greenhouse a thorough cleaning. Be sure to use a mild disinfectant soap to clean with. Get the mold out of every nook and cranny. I know that we all keep our greenhouses relatively clean, but this is just something that happens with all of the humidity. Check any corners or places where there may be potential leaks and be sure to seal them up. Clean your benches if you have any. Repair or rework your flooring, depending on what you have in place there. Check all lighting and electrical systems. If need be, get a certified electrician in to help you with this. You can never be too safe. Same with your greenhouse heater. Whether you have electric, natural gas or propane, be sure to check your greenhouse heat source and be sure that it is properly connected with no leaks. Also, turn it on and make sure that it works. You may have to go out later in the evening as the temperatures drop to try this, but trust me, it is worth the time and effort to do this. In fact, I think that checking your heating system is the most important part of getting your greenhouse ready for winter. I cannot tell you how many times I have received panicked calls that it is going to freeze tonight and my heater won’t come on. There is just no way to get parts or a new heater to you fast enough. So, even though we are still enjoying summer time temperatures, think about the winter and your greenhouse now.
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.
This one is for all of you d-i-yers out there. This article is from our friends at Garden and Greenhouse Magazine. It discusses the different types of hydroponic systems and how to set up your own hydroponics in your hobby greenhouse. I have owned a greenhouse full of hydroponic systems, experimenting with the different types to see which I liked the best. I think I preferred the NFT system. We used it to grow basil. It was as simple as could be.
Experimenting with hydroponic gardening is a fun and productive way for greenhouse hobbyists to expand their horticultural knowledge. The term “hydroponics” is a general name that encompasses all methods of soilless gardening. In other words, there is a multitude of ways to garden hydroponically. However, don’t let the seemingly infinite amount of hydroponic systems deter you from giving hydroponics a try. One of the best ways for greenhouse hobbyists to break into hydroponic gardening is by making a homemade hydroponic system.
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.

Building a Polyfilm Greenhouse? Not sure how to attach the film to your greenhouse frame? This video discusses the use of batten tape or base and wiggle wire systems. They are both excellent for wood frames. The wiggle wire system is good for metal frames as well. As always, we hope you find this edition of “The Greenhouse Minute” informative and helpful.
