Movable Plastic hangers

Riga makes plastic hangers made specifically for their greenhouses that will easily snap into the groves in the aluminum frame. These hangers come as a set of 10. If you attach twine of rope to the hangers for support of the growth of tall plants.

Adjustable Metal Hooks

These adjustable metal hooks are made specifically for Riga greenhouses. They are only available in sets of five. These hooks come in handy for hanging lights, fans or flower baskets in your greenhouse.


The Riga II Greenhouse has a unique optional two layer shelving system with removable shelf inserts to allow taller plants to grow unobstructed. The shelving is suspended from the ceiling without braces underneath allowing for more storage space for gardening tools like a wheelbarrow or long tools inside the greenhouse. The shelves are made from a twin wall polycarbonate material, allowing for much better and more even light distribution through the greenhouse to help with plant growth. The shelves are made to go from one end of the greenhouse to the other. The depth of the top shelf is 14" while the depth of the bottom shelf is 25".

Note: Two top shelves and two bottom shelves can fit in the greenhouse. If you would like to purchase an additional top shelf or two of the same bottom shelf these items can be purchased separately. Black planting trays designed to fit all RIGA greenhouse bottom shelves are also available separately.

Extra Roof Window

When living in hot climates it is important during the summer months to have proper ventilation for the health of your plants. You are able to add additional roof windows for your greenhouse. These windows have automatic window openers but does not need electricity. It comes with a special cylinder which expands and contracts due to temperature changes. It pushes the window open when it gets hot inside and closes the window when it cools down. You are able to adjust the temperature range. The roof window are attached with a tongue and grove hinge system, which spans the full length of the top profile of the window.

Hoklartherm Riga IV 6'11" H x 7'8" W x 14' D Polycarbonate Commercial Greenhouse


Well Built and Great Customer Service

Tony from Los Alamos, NM

The Riga IVs Greenhouse Kit is built of good quality aluminum extrusion frame members. The aluminum frame went together well and the double wall glazing fit into the aluminum without much difficulty. It does take two people to do the installation and a third person would come in handy. A few of the aluminum pieces were damaged in transit. The distributor in Texas was quick to send out new replacement pieces for the ones that were damaged. They were very nice to work with work with concerning any problems related to this German made greenhouse.
Without question, I would do business with them again.

Cindy from Val Caron, ON– Verified Buyer

This greenhouse is AMAZING! VERY well built and fantastic HOWEVER it is HORRIBLE to put together! The instructions SUCK (you can't imagine to what extent) so it's very frustrating to put together but ifwhen you do you won't be sorry you bought this. It's fantastic and wayfair warranties everything damaged. Also the company who is providing the greenhouse was phenominal as well. VERY good buying experience (not so good assembly experience)
