Why You Need the Best Greenhouse Kit

The enhanced environmental conditions in a greenhouse offer your crops and flowers an ideal environment required during the early stages of growth. Or, if you are growing through the year, it can lead to larger yields on your crops or bigger blooms.

To erect a greenhouse, a gardener needs to construct foundations, and then you can build the rest of the structure.

However, you can find companies that offer greenhouse kits, which are easy to assemble. A gardener can build a DIY greenhouse in the space of a day or less with a couple of people and minimal tools required.

Most plants are vulnerable to bad weather, particularly when planting. Your greenhouse can offer this protection. Also, they can receive protection from UV rays and frosts that hit your garden unexpectedly.

The best greenhouse kits make everything far more straightforward than it used to be. You also have the flexibility to move them as you wish if you move home or change your garden landscape.

You can find all options in our greenhouses reviews, from the plastic cover that is virtually unbreakable to exotic greenhouse structures that can take pride of place in your garden.

Best Greenhouse Kit Buying guide

Now you have seen some of the best options available, here’s what you need to check to make sure you have the right choice to meet your gardening needs.

Types of Greenhouses

You need to know the type you want. If you’re going to grow vegetable all-season and extend your growing season, you may need more square feet of growing space than just starting flowers before planting in the back yard.

Size of Greenhouse

Yard size is the most significant factor when buying a greenhouse kit. A large greenhouse in a small yard looks weird, and neighbors may complain should it affect their view.

For small yards, then 4′ x 4′ walk-in greenhouse kits are all you need to grow small vegetable crops or start flowers off early in the growing season.

Greenhouse Panels or Covers?

The next thing for greenhouses for home is deciding on paneling and cover materials as you will notice a big difference.

If purchasing your greenhouse for starting seedlings, you’ll need clear twin wall polycarbonate panels. Clear panels create direct light transmission, which produces the ideal environment for germination. However, with some clear materials, they may not be UV resistant. Such UV rays can be harmful to your plants and also for you.

For growing plants to maturity, you can use opaque panels to diffuse light and promote flowering. If growing from seed to harvest, you want thick twin-wall polycarbonate side panels.

Durability

It would help if you also were sure your greenhouse could withstand the rigors of winter, although this does depend on where you live. Any frames that come with covers should be powder coated to be rust-resistant.

They should also be constructed to allow easy access yet keep out any deer or rabbits.

Final Verdict

When checking these garden greenhouses, some were a little elaborate and not ideal for many urban gardeners. However, when you look at the price to performance, it was clear the Mini Walk-in Greenhouse Indoor Outdoor -2 Tier 8 Shelves- Portable Plant Gardening Greenhouse (57L x 57W x 77H Inches), Grow Plant Herbs Flowers Hot House was rising to the top.

It doesn’t have the looks of larger models, yet you get shelves you don’t get in more expensive models, and the PE cover performs the same as the polycarbonate panels. Your plants get the best environment possible.

Finally, you can assemble this great little greenhouse by yourself in next to no time. Before you know it, you can protect your plants from any weather.
