When shopping for the best 4’ x 8’ greenhouse kit, there are several aspects and features that you need to consider so you can make the most out of your purchase. Below are the most important ones to keep in mind.

  • Your Location – both in terms of on the globe and on your property
  • Greenhouse Size – more cubic feet means more work to adequately heat and ventilate
  • Construction Materials – some materials trap heat better than others, duh
  • Water Supply – how are you planning to get water into your greenhouse?

If you feel like you need a little bit more information in general on greenhouses than this guide provides, then consider reading our Ultimate Greenhouse Guide to become more acquainted with these glorious contraptions.


It doesn’t matter if you got the most expensive greenhouse on the market, a bad location isn’t something it can recover from. The ideal spot for setting up a greenhouse is somewhere that’ll let receive as much sunlight as possible. This goes for all of the sides. 

The best positioning for your greenhouse is when it’s oriented towards the east-west, but if you can’t achieve that, there are other solutions. Just about any other direction will do, given that it allows for adequate exposure to sunlight. 

Don’t pick a spot that’s close to big structures. These can cast a shadow over the greenhouse, inhibiting its exposure to the sun. 

Additionally, avoid setting up your greenhouse near trees, walls, buildings, hedges, or anything you think may prevent enough sunlight from reaching the greenhouse.


The size of the greenhouse depends on the type of crops you plan on growing as well as your budget. Today, we’re reviewing 4’ x 8’ greenhouses, which offer plenty of room for the average gardening enthusiast. 

These greenhouses, however, differ in height. So make sure you have enough height if you want to grow climbers.

Construction Material

Next, you need to think about the type of construction material of the greenhouse. 

In general, greenhouses are made using plastic or glass. If you’re worried about the risk of breakage, you may be better off with tempered glass or plastic.

Water Supply

As you probably know, water is essential for any garden to grow. So before you spend money on a greenhouse, you need to make sure that there’s a reliable supply of water available to accommodate your plants.

Watering methods come in different types. If you’re opting for a sophisticated in-greenhouse water supply, you may want to consider some plumbing. If you’re not always present at your home, it’s a smart idea to install a semi-automatic system.
