Herb Growing In Greenhouses: How To Grow Greenhouse Herbs

by Jane on October 26, 2020

The miniature greenhouses are used for growing herbs and other medicinal plants. They are usually made from plastic or wood. Some of them have a glass cover so they can be seen easily when needed.

The size of these mini greenhouses depends on the type of herb being grown, but most are around 2 meters (6 feet) square. These mini greenhouses are useful if you want to grow a few herbs at home without having to buy large quantities of seeds or bulbs.

What You Need

There are two types of mini greenhouses for herbs. One is made with plastic, which is cheap and easy to use. Another one uses wood, which requires some care in order not to damage the plant during harvesting time.

What You Need

If you’re looking for a simple way to grow herbs indoors, then plastic greenhouses are the best choice. They are inexpensive and easy to use. There are many different kinds of plastic greenhouses available, such as those made out of polystyrene, PET bottles, and even old milk jugs.

Plastic greenhouses come in various sizes and shapes depending on how much space you need to grow your herbs.

You can also build your own mini greenhouses at home using recycled materials. Just by recycling a few plastic bottles or milk jugs, you can create a mini greenhouse for your culinary herbs.

Wooden Greenhouse: What You Need?

If you’re looking for something that lasts longer, then wooden greenhouses are the best choice. They last for years and years with minimal care (unlike the plastic ones, which tend to deteriorate after just a few seasons). They’re also more attractive if you’re looking to add a decorative touch to your garden.

Choose the size you want depending on how large you want your herbs to grow and how many different kinds of herbs you want to plant. You can buy them ready-made online (search for “wooden mini greenhouses”), or you can build them yourself.

The materials you need to build your own wooden mini greenhouse depend on the size of your greenhouse as well as what type of wood you want to use. The size of the building you want to create will determine how large (or small) you want the pieces of wood, so you’ll need to use your judgment on that one.

You’ll need the following materials no matter what size you build:

Here’s what you’ll need if you want to build a mini greenhouse that’s around 2 feet by 4 feet:

One 8-foot 2×4 (sides)

One 8-foot 1×6 (roof)

13 1/2-foot 1×2’s (framework)

Two buckets (to mix cement)

Lumber (to frame door and window openings)

How to Build the Wooden Frame

Cut two 2-foot-4-inch lengths from an 8 foot 2×4 and nail them vertically into the ground where you want the front and back walls of your greenhouse to be. This will form the backbone for your greenhouse.

You next need to attach the short side walls. Cut two 1-foot-6-inch lengths from an 8-foot 2×4 and nail them on at a right angle to the back wall, so that they form a “T” shape.

Nail the long sides of the “T” to the front and back vertical pieces. This will give you a basic rectangular structure that you can reinforce and continue to build upon.

Framing the Roof

The next step is to make sure your roof is nice and strong. For this you’ll need an 8-foot 1×6, which should be long enough to span the width of your greenhouse. However, if it isn’t then you’ll need to add a couple of 1×2 or 2×2 braces across the front and back at either end to give the roof extra support.

If you find that your 1×6 is long enough, then nail it in place spanning the width of your greenhouse.

Time to build the rafters. Cut nine 2-foot-3-inch lengths from a 1×2 and nail them across the 1×6 at equal intervals. These will give added support to the roof as well as giving it an aesthetic touch.
