The Key To Optimal Growth in Your Greenhouse

Growing Healthy Plants in Greenhouse

Greenhouse and Indoor Garden Growing

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.

The Importance of Consistency in Greenhouses and Indoor Gardens

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.


Greenhouse Shade Cloth

Reflective Shade Cloth for Greenhouse

It seems to me that a lot of people struggle with the decision on which shade cloth is best for their greenhouse. I think they are way over complicating the issue. A greenhouse shade cloth is pretty much like stepping under a shade tree in the summer. You have felt the cooling pretty much right away when you do this. A shade cloth does pretty much the same thing. There are several different choices of material, but the differences are pretty basic. The woven shade cloth is the least expensive. It is a black color. It must be taped on the edges, or it will ravel. It is best used on the outside of the greenhouse. The next choice is a woven shade cloth. This will be intermediate in pricing. It is really nice, as it has some stretch and will not ravel, so the taping is not a necessity with this type. Although we do tape all of our edges so we can add grommets for simple installation. I personally prefer to use this with a greenhouse with automatic roof vents. The way we have always done it is to put the shade cloth on tight on the ends. As we near the vents, we don’t fasten the shade down as tight. We will go back for the next 3 or 4 days and adjust as needed. You want to make sure that there is no strain on the vents when they are trying to open. The next choice is the reflective shade cloth. This is the most expensive, but it is a good choice to use on the inside of a greenhouse. A lot of commercial growers like this for exterior applications as well. Probably the most common question I get is – what percentage should I use? The higher the percent, the more shade you will get. I have found through the years that a lot of orchid growers will prefer a 50% shade cloth. For general purpose growing, ie vegetables, annuals, etc, a 60% to 70% shade is typically used.
