Welcome to our guide of the Top 10 Greenhouses on Amazon in 2018!
Farmers and Gardeners everywhere, in all climate zones appreciate the power of Greenhouses. They allow us to extend the season and grow things that otherwise, would not grow as well in an outdoor climate.
There are many customization aspects of Greenhouses but they all certainly have the same needs and concerns to consider. With the growing demand of greenhouses, ordering online is a safe and easy option for many small-scale greenhouses.
In our guide of the Top 10 greenhouses for 2018 we will preface you with the major concerns with greenhouse care before breaking down the Pro’s and Con’s of each Greenhouse. Their best uses, and their price point.
How do Greenhouses work?
The temperature in a greenhouse is due to the amount of Solar Radiation that passes through the transparent, or sometimes semi-transparent roofing and wall structures. As the structure is closes, the warmer air may not be able to escape (otherwise known as convection) so the temperature in the greenhouse will steadily rise.
Heating, Cooling, Energy, and Ventilation
When no proper ventilation is present, the growing plants and soil within may become prone to issues, such as molds, fungal growth, and defective growth. These are caused by conditions such as humidity, and temperature regulation issues. For this reason, re-circulation vans, and vents will be useful to optimize the functionality of your greenhouse.
This is not to be mistaken with the theory known as the “greenhouse effect” that is associated with environmental and atmospheric concerns.
Heating and Electricity
When considering the long-term costs of operating a greenhouse, the energy inputs of any heating and cooling system for a greenhouse will be a pertinent concern to address.
Passive heating exists and may be utilized to lower energy input. Some examples include waste heat from livestock, solar energy, black water barrels that can trap extra heat, and window actuators to open windows on the spot when a temperature difference is detected.
Many Greenhouses boast the wonderful amenity of natural lighting. If you were to want to work at night, utilizing grow lights and LED lights will not only help guide you through the dusk and dawn hours of the day, but increase yield due to their powerful effects on seedlings. For more information about growing plants with lighting please read our guide on How to Germinate Healthy Seedlings for more information on grow lights!
