Want to grow oranges in Canada? Then let me tell you about greenhouse farming. It’s without doubt the future of farming.
Weather has mystified farmers for millenia, but the humble greenhouse is changing that. Greenhouse farming is a cheap and robust solution to an unpredictable climate. Most new farming models make heavy use of greenhouses, notably
- aquaponics (pictured)
- SPIN farming
- vertical farming
A greenhouse farm can be as simple as an herb garden in a windowsill, or as advanced as a 55-foot computer climate controlled behemoth. A greenhouse is like a good suit. It should be fitted perfectly to your needs.
Many greenhouses are mode of glass, but plastic works as well or even better in some cases. In its most essential form, a greenhouse is a clear box that allows infrared light through, which is converted to heat upon hitting the interior surface. The heat energy cannot easily exit the box, which raises the temperature inside. Our entire planet acts as one giant greenhouse in this way, allowing infrared energy in and keeping it there as heat.
The most ambitious greenhouse farming projects put entire ecosystems inside greenhouses, including humans. These experiments are carried out with the end goal of space colonization in mind. Space colonists in the distant future may live in cities housed in giant glass bubbles, essentially giant greenhouses. In the future, greenhouse farming will merely be called “farming.”
