Roll-N-Grow™

Greenhouse Mat Systems

Heating a greenhouse floor area or a bench has never been easier! We offer our Roll-N-Grow mat systems in two styles, one optimized for bench application and one that’s just right for heated floors.

We have teamed up with Ludvig Svensson, the largest textile manufacturer in the industry, to bring you this exciting product. BioTherm Microclimate tubes are woven directly into a “weed mat" fabric and shipped on a roll just like standard ground cover fabric.

Roll-N-Grow for benches

Bench heating just got easier to install! Roll out the heating mat, hook up the fittings and you are ready to grow. BioTherm tubing is woven in on 2" on center spacing which optimal for propagation and most general greenhouse bench heating applications.

Most growers install this material on the cross members of commercial greenhouse rolling benches before placing expanded metal on top. You can also roll it out on existing growing surfaces of wood or other materials. Set plants directly on the mat, hook up the hot water lines (we design that part for you on a custom basis), and enjoy supreme growth and energy efficiency!

Like a carpet, your growing surfaces can now be covered with growth-enhancing gentle heating in a fraction of the time it used to take, with almost none of the labor associated with traditional greenhouse bench top heating systems.

Roll-N-Grow for floors

The BioTherm tubing is woven in on 3" centers, which provides optimum even greenhouse heating for gently warming crops like bedding, perennials in flats, or potted crops produced on the floor. This is the most cost effective and simple way to get warm floors in your greenhouse operation. Installation is simple:

• Clean the area and bring in gravel for drainage (if necessary)
• Roll out the Roll-N-Grow for floors mat material
• Connect to pre-assembled header manifolds
• Connect manifolds to heat source using piping and system design provided by TrueLeaf
• Control the heating system using the temperature of a sample flat or pot in each                                                                                                            zone

This product is designed to withstand foot and cart traffic. It’s a great, cost-effective way to heat any floor area, without having to bring in costly concrete.

If installed properly, both of our Roll-N-Grow Mat systems can be rolled up when not in use! Think about seasonal production areas, outside beds or any growing application where temporary bottom heat might be beneficial...your imagination is the only limiting factor!
