If you dont want a greenhouse that takes too much space or one that is a permanent fixture in your backyard, a portable greenhouse is your best option. A portable greenhouse is also less expensive than a normal greenhouse and can be set up in a matter of minutes. Just like any other type of greenhouse, you can find a portable greenhouse construction kit at your local gardening store. There are many types of portable greenhouses, and you can choose one best suited to your needs and the available space. A portable greenhouse can also be used to cover a particular patch of vegetables or fruits. For instance, you can extend the growing season of your tomatoes up to fall.

Constructing a portable greenhouse is inexpensive costing no more than $500. The most common kit is one that looks like an accordion when opened. Once opened, fit the spreader bar into the bracket on the roofline. Normally, you should be able to construct your portable greenhouse in less than three minutes.

A portable greenhouse is covered by tear-resistant plastic. This plastic blocks UV rays and allows 75% of the received sunlight to permeate through it. This is best suited for seedlings. Zippers join the individual sheets of plastic, and the ones on the roof can be opened to let air in. This plastic is should last up to five years depending on your usage. All portable greenhouses are made of lightweight aluminum, so you will have to be careful during storms. Tie them up to a heavier support or secure with a heavy object to protect your greenhouse from flying away along with all your prized plants. The greenhouse may be collapsed and stored during the winter if desired.
