Building a Greenhouse in Phoenix!

My review of the Palram Harmony Greenhouse and the potential Challenges.

Palram Harmony Greenhouse

If you’re a gardener or hobbyist interested in purchasing a greenhouse kit and you’ve done your research on the necessity of such a structure, then you know that there are quite a few manufactures to choose from. You’re now in a phase of finding out which brand and model is best for you.

Before you make that purchase, you should make sure that you know the upside and the downside of growing plants inside the greenhouse, as well as the climate that you live in.


A Greenhouse in Phoenix?

We had to make some serious considerations when it was time to purchase our greenhouse because we live in the Southwest and there are special needs for green houses in this heated climate.

There are many brands out there on the market. For us, the brand that caught our eye was Palram.

Palram is a company that builds durable products for the outside of the home and the home garden; like greenhouses, gazebo’s, carports, storage sheds, patio covers, and other items.

It has been 4 years since we bought and assembled our 6’ X 8’ Palram Harmony greenhouse. The idea of such a purchase was to plant our flowers and vegetables in the unit through all the seasons. We are in North Phoenix and our Harmony went through monsoon weather, near freezing cold, and summers of extreme heat and it’s still standing strong.


Construction Begins…

We ordered our greenhouse from Costco and the unit arrived in several boxes, and it also had detailed and concise instructions with a numbered and lettered parts list.

Before assembly we leveled and built an adequate foundation for it and then build the base frame as per instructions.

The type of flooring you decide to lay down in your greenhouse is up to you.  You do have options; like bolting the frame to treated landscape wood or masonry to the bare ground, or treated wood flooring, or pouring concrete. We decided on putting a weed barrier down before placing rubber shop tiles on the floor and it has worked out perfectly

Overall assembly took a few days because of the Arizona heat, we started assembly just before dawn until mid-morning and continued late afternoon to just after dusk. We had no missing or defective parts issues. All parts fit together easily and after assembly was completed, the structure stood with a sturdiness.

The most important thing that you need to know is that once your greenhouse is constructed, you’re going to have to secure it. The Harmony is rated to withstand winds of 55mph structure, but you will have to anchor it or bolt it to a foundation. We used an anchors system that is available from Palram to secure it to the foundation and it works well.

That same year, actually a few months after we constructed our greenhouse, one of the worst monsoon storms hit Phoenix. This storm came with strong winds and heavy rain and the greenhouse withstood it and it was not affected by it at all.

As a matter of fact, the greenhouse survived a lot of Arizona weather during the years after it was constructed. Through the extreme heat, record cold, heavy rain and the Harmony and its polycarbonate panels survived the elements and is still standing strong.


Accessories and add-ons?

Accessories are available through Palram that will help you get your greenhouse going. We did purchase the shade, automatic vent opener, heavy duty wall shelf, plant hangers, and the irrigation system and also purchased quite a few other accessories for the greenhouse through places like Lowes, ACE, Walmart, Home Depot, and various online sources.

We were able to grow plants successfully inside the Harmony, during the summer month due to use adding a portable evaporative-cooler and misters, while keeping an eye on the humidity levels inside the greenhouse.

Some Considerations…

The Palram Harmony greenhouse is a sturdy structure that is perfect for the novice and experienced gardener alike. It is easy to build with a little patients and organization. The unit can withstand up to 55 mph winds as per specifications, but there needs to be effort on the part of the purchaser. There are plenty of add-ons and accessories available to help you get the most out of your purchase.

You just have to do a little research. There are plenty of blogs and YouTube videos that will give you ideas and advice on how to get the most out of your Harmony.
