Hoklartherm Riga XL 5 Greenhouse 14x16

Description

Hoklartherm LogoNo matter what weather extremes you are facing. Growing fresh veggies, fruits, herbs, and flowers all-year-round is possible with the Hoklartherm Riga XL 5 Greenhouse. Investing in a sturdy greenhouse like this one is the soundest decision you can make.

The Riga XL Greenhouses offer 16mm triple-wall Polycarbonate panels. Other greenhouses often use less than 8mm, which only functions as a season extender. The Polycarbonate glazing used on Riga greenhouses is made in Germany and is considered to be of excellent class.

Another significant benefit is the sturdy framework. It is made from anodized aluminum and is tougher than the framing of average hobby greenhouses. The frame profiles are permanently connected to each other and will not become detached over time because of extreme weather. The frame profiles are solid or have a wider diameter than other greenhouses. That presents a solid construction!

The “onion” shape, also known as Gothic arch is one of the main reasons for its remarkably high wind and snow tolerance. Snow will simply slide off the sides. The form also helps withstanding intense winds.

The heavy-duty barn-style doors on both gable sides are very helpful if you have big equipment. It is so easy to get in and out without the hassle of damaging some plants or pots while passing through. It measures 37.5in wide x 74in high.

The Riga XL 5 Greenhouse is a combination of durable materials and long-lasting hardware. It is notably the toughest greenhouse of its dimension, which is reinforced by the long warranty.

Door Extension Kit

You only need this if you want to build your greenhouse on a stem wall (foundation wall). It essentially adds a piece of Polycarbonate above the door in order to close it off when the door is installed on ground level (check photo to get a better idea). Here is a link to the Door Extension Kit.

Other Riga Accessories

There are plenty of other accessories that you may want to add to your order. We would just advice you to think about if you really need it for your specific circumstances. Not every accessory is needed to successfully grow your own produce.

Wind Restraint System for Roof Vents

This nifty little add-on will keep your automatic openers save on stormy days. We do recommend it to people who experience storms often, especially if you don’t have many wind breaks in your garden. The automatic roof vent openers work with the indoor temperature. So, they may open even if it’s very windy outside. Therefore, it is wise to secure the vent. Check it out here!

Seed Trays

If you want to use the shelving for seed starting and you don’t want to use individual pots, you can get these seed trays. They fit perfectly on the shelf. Check them out here!

Greenhouse Misting System

A misting system cools down the greenhouse on hotter days. It also takes away the task of watering frequently (you still may need to manually water certain plants). However, you may not need it if you don’t have hot summers and if you are growing plants that don’t do well with overhead watering. Check out the misting system here!

Plant Hooks

If you want to utilize hanging pots or plant wires, these hooks may be beneficial to get. They attach to the greenhouse frame with a T-bolt head. Check them out here!
