Portable Greenhouse Kit – Ventilation, Heat & Light Tips

Do you want a spacious, walk-in greenhouse for your backyard – that is light enough that you can move it? This tunnel-shaped portable greenhouse kit weighs less than 50 pounds, yet it is large enough to have walk-in entrances on 2 sides.

Built-in Greenhouse Ventilation & Heat:

In addition, this greenhouse features 6 screened windows to provide optimal air flow. The cross-ventilation design also helps with humidity and heat control.

Alternatively, you can close the windows and doors to keep your plants warm and protected year-round. For such an affordably-priced structure, you really get lots of versatility. Plus, it makes a great beginner greenhouse too.

Outdoor Greenhouse Heater to Keep Plants Warm During Winter

Note: During winter, use an outdoor heater if you need extra warmth, as the canvas doesn’t retain a lot of heat. That said, the polyethylene cover does have some insulation.

And as far as snow goes, the framework can handle a light load, but not heavy amounts of snowfall. So, this is definitely not as sturdy as a polycarbonate greenhouse kit.

Does a Greenhouse Need Direct Sunlight?

As you can see, this grow house has an opaque cover. Therefore, the plants inside receive diffused light rather than direct sunlight. Compare other greenhouse kits here.

Although full sun is better for germinating seeds, opaque greenhouses can help plants grow more evenly year-round. In other words, light can hit all areas of the plant rather than the plant having to search for the direction of the sunlight.

Greenhouse UV Protection & Diffused Lighting

As a result, many people choose frosted or opaque material. Plus, the polyethylene cloth on this structure provides UV protection as well.

Note: I think that this greenhouse appears larger in the photos than it actually is. Keep in mind that it’s only 10 feet long and 6 feet 6 inches wide, so you can set it up virtually anyplace where you could park a small car.

Indoor/Outdoor Plant Shelves for Greenhouses

How to Arrange Plants
in Your Greenhouse:

You have lots of options when it comes to organizing your enclosed garden. For example, some people place grow bags on the ground while others set up plant shelves.

You can also hang plants from the steel ceiling frame and take advantage of space above the shelves.

How to Set Up Your Greenhouse:

This frame and canopy are very simple to put together, although the job requires some work. You can see the assembly instructions here

Essentially, you connect the frame pieces together, pull the tarp over the roof and then attach the cover to the frame with the velcro straps. Last, you secure the frame to the ground using the included u-nails or stronger rebar stakes.

Heavy Duty Steel Greenhouse Frame

This tunnel-style backyard greenhouse comes with a heavy-duty galvanized steel frame that won’t rust. It secures to the ground with U-nails that come in the package. Plus, you can add extra wind protection with the included rope.

However, if you have consistently. windy conditions, you may want to invest in sturdier anchors like 16″ rebar stakes. The canopy and frame are fairly lightweight for their size.
