Allowing natural air to flow through your greenhouse is one of the essential elements needed to grow plants and flowers that will thrive. If youíre planning to build a hobby greenhouse, whether itís attached or separate from your home, itís important to look at the ventilation system.
Home greenhouse plans should include adequate window openings for the particular type of plants, flowers and seeds that you will be cultivating. Greenhouse windows are a simple way to make sure youíre greenhouse is getting the natural air flow it needs. You can avoid expensive ventilation systems when you plan it right at the building stage.
If youíre looking to install greenhouse windows into an already existing structure, you may be surprised at how easy it can be. For instance, most greenhouse windows have been specially designed to slip over an opening in an exterior wall.
Hereís a look at some of the decisions you will need to make when it comes to choosing a greenhouse window that suits your needs:
The first thing you will need to do when choosing a greenhouse window, is to calculate the size. This means that you need to measure youíre opening for a better idea of what size frame you can use.
Remember that leave approximately 8-12 inches of height and 3-4 inches of width around your window, for a hassle free installation.
Always calculate a space of 24 inches below the window for the strut.
In most hobby greenhouses youíre windows wonít provide you with roof vents. Therefore, you will most likely need to look into getting both a heating and cooling system that can add to the natural ventilation.
Using screened storm windows in your greenhouse achieves cross ventilation, which is important for filtering.
Greenhouse experts suggest that installing a plant light above your ventilation window, and shelving below will increase the potential benefits of your greenhouse hobby.
As a greenhouse gardener you will need to understand why ventilation is so essential to the life of your plants and flowers.
The air flow in your greenhouse enables your plants to get fresh air, without the heavy particles that so often contaminate a gardenerís plans.
How greenhouse ventilation works is really quite simple.
A ventilation system will remove the stale indoor air of the greenhouse and circulate it back outside. In the same beat, new, fresh air will circulate back into the greenhouse, where youíre plants will again convert it into carbon monoxide.
You will need an adequate source of ventilation, whether it be natural or induced by fans. Changing ventilation systems with the climates of winter, spring, summer and fall will allow you to keep your plants alive all year around.
Hereís a look at the most important reasons for using a ventilation system in your hobby greenhouse:
- Air Circulation
- Maintain Humidity
- Control High Temperatures
- Stabilize Gas Concentration
Controlling high temperatures inside the greenhouse are an issue that a greenhouse gardener must address in the summer months.
Due to the fact that greenhouse temperatures can rise above the outside air temperatures, itís important to find a ventilation system that can sweep air over the soil.
Closing the gap between the outside and inside air temperature is essential for summer indoor gardening.
Solar radiation inside the greenhouse can be caused by a number of factors, including the glazing grade on your windows. To avoid the effects of solar radiation, your plant soil must be kept free of these high temperatures.
A good air ventilation to use during the summer months is one that changes air at least every three minutes. If youíre willing to spend a little extra money, try one that has up to three air changes a minute.
Ventilation during the winter months is slightly different, as its purpose is to maintain a certain level of humidity inside the greenhouse.
Outdoor air circulated into the greenhouse will eliminate the moisture from the warm indoor air. This means that your plants can avoid the damage produced by excess humidity, including: leaf mold, stem rot, infection, and fungus diseases.
To avoid these plant killing conditions, be sure to maintain a humidity level below 70% during the winter months.
Lastly, itís important to cultivate natural air flow throughout your entire greenhouse in order to keep the gas concentration level. This is needed all year around without fail.
