Culti Cave TRIO is made from a high-grade thick UV stabilised PVC fabric. It includes a green plastic roof hood/fly sheet which gives added insulation, UV protection, and shade.

The CultiCave TRIO greenhouse system also incorporates two adjustable mesh ventilation flaps in the roof as well as a handy velcro-detachable rear access panel within the rear door panel.

Its dimensions are the same as the standard CultiCave at 200 cm (6 ft, 6 “) wide x 170 cm (5 ft, 6″) high x 80 cm (2 ft, 6″) deep. It’s simple to assemble (we recommend two people) and is supplied in a zipped carry bag within a carton 60 cm (24″) x 23 cm (9″) x 23 cm (9”), weighing approx. 6.5kg (14 lbs).

There are door panels to both the front and rear. The doors have 3 zips: one opening vertically to the left, another to the right, and a 3rd horizontally across the bottom. The zips are covered by a weather flap to limit potential water ingress. The doors can be partially opened for easy access and ventilation – or they can also be completely detached. An additional front mesh door panel is supplied for use in warmer weather. This enables maximum ventilation whilst still protecting your produce from insects and birds.

Culti Cave TRIO is a modular system. Unzip and remove the front panel of one and the rear door of another. Put the two doors away for future use, then simply zip the two CultiCaves together to extend your greenhouse. You can zip a third or fourth – as many as you like to create your very own CultiCave tunnel! What’s more, you can add a TidyTent storage unit to create a CombiCave – a combined storage unit and greenhouse!

And now with the new CultiCave XtendaHood and TidyTent XtendaHood there are even more options! The CultiCave mini greenhouse system is completely modular. It’s all about caves and hoods!

CultiCave Culti Cave PVC Greenhouse – Why do I need a Culti Cave TRIO?

Greenhouses are costly, difficult to erect, and often require quite a fair bit of space besides being a permanent structure. You probably only need your greenhouse at certain times of the year but once it’s in place, they’re there all year around.

Wouldn’t it be nice if you could take it down in a matter of minutes and store it away under your kitchen sink, for example, until next year, or even until your garden party is over? Well, you can if you have a Culti Cave TRIO.

•Beware of cheap alternatives! Unlike many other plastic grow houses, the Culti-Cave TRIO is made from tough UV-stable PVC and will not perish and disintegrate in 12 months’ time!

•It is significantly bigger than most others (over 4 times the volume of the current market leader) enabling tomatoes and larger plants to be grown and allowing you quick, easy access.

•Ideal for larger plants and flowers – also tomatoes, cucumbers, melons, strawberries, squashes, etc.

•Perfect for growing plants in grow bags, designed for four standard grow bags

•Sewn-in groundsheet to stop slugs, insects and other garden pests from getting in – also promotes a more humid growing atmosphere.

•Quick and easy to install – either wall-mounted or freestanding.

•Easy to ventilate on hot days by either partially or wholly unzipping the front and rear panels.

•Zipped door panels on both sides for quick and easy access.

•Comes complete with an additional mesh door panel to maximise ventilation while keeping out pests.

•Modular – two or more units may be zipped together to extend the size.

CultiCave Culti Cave TRIO PVC Greenhouse – UV stabilised PVC*

Developed primarily for larger potted plants, shrubs, climbers, and vegetables, the Culti Cave TRIO has rapidly become a welcome phenomenon within the Gardening community, providing excellent protection from those relentless garden pests, insects, and unforgiving weather.

In our own experiments, we found that the air temperature inside the CultiCave TRIO, when measured after a sharp overnight frost, was around 9 degrees warmer than outside. That’s the difference between life and death for many vulnerable plants.

The Culti Cave TRIO modular mini greenhouse system is designed to protect your new plants from the wind, rain, and snow with its unique, curved shape. It is made from a high-grade UV stabilised PVC for longer life providing excellent protection and an easily maintained, durable wipe clean surface.

In addition to the saving in terms of cost, erection time, and space required, your Culticave will shrug off the unwanted attention of wayward balls of all sizes. If a child should run into it, you’ll have a clip for “You’ve been framed”, rather than a pile of broken glass and a trip to A&E.

The CultiCave is protected by European Community design registration and international patents.

*Culticaves are made of PVC, which is a 100% recyclable material. PVC is an exceptionally durable plastic, used for instance in water supply and sewage pipes, which can last for over 50 years. PVC is 100% recyclable and has the longest history of recycling among plastics. The PVC industry perhaps has a better understanding of its products than manufacturers of most other synthetic materials. In Europe alone, more than 260,000 tons of post-consumer products were recycled in 2011 through industry-sponsored schemes.
