AQUATHERMAT is a heated capillary mat system.

An investment in AQUATHERMAT can pay for itself in a fairly short time - often a year or less. This properly irrigated and heated micro-climate assures an optimal growing environment for your plants, without reducing moisture levels: you achieve a higher germination rate in a shorter production time!

AQUATHERMAT offers superior heat transfer capabilities as well as high capillary properties. Heating tubes warm up the water contained within AQUAThERMAT to distribute it to the root system by the pot drainage holes. AQUATHERMAT puts the heat exactly where it counts...without wasting energy on heating the vast volume of air of the greenhouse.

AQUATHERMAT stimulates the development of the root system, the leaves and the size of the stems. Since there is a higher percentage of mature plants, you significantly increase your crop turnover while drastically reducing your production costs!

For years, greenhouse growers have been using root zone heating to grow bigger, healthier plants. AQUATHERMAT uses the same efficient concept, but takes it one step further by integrating heating tubes to the efficient design of AQUAMAT:

  • Cuts energy consumption by 45 % or more!
  • Creates a strong root system & accelerates plant development by up to 35 %.
  • Heats substrate evenly and rapidly without reducing moisture levels.
  • Stimulates root formation and seed germination. 
  • Drastically improves production time.
  • Controls run-off, saving up to 80 % of lost water and fertilizers.
  • Promotes greater crop uniformity and top-grade plants.
  • Uses five to six times less energy over all other root zone heating systems.

IRRIGATION

The amount of watering will be calculated and adjusted according to the properties of substrate used and the type of plants grown. Subirrigation is not recommended for seedlings and cuttings. Therefore, we recommend to use a mist watering until the root system is well established.

Small quantities of water pulsated regularly are preferable to one long irrigation cycle (e.g. 3 cycles of 3 minutes each rather than a single 9-minute cycle). The Microfab upper layer will therefore have time to dry which prevents the growth of algae on the surface.

 

BENCHES

Benches must be flat and level so as to prevent any accumulation of water. To maximize AQUATHERMAT energy efficiency, it is recommended to cover the table's surface with an insulating material which is resistant to humid and hot environments (e.g. styrofoam).

 

CONTAINERS

The container or tray design must be accessible to sub-irrigation systems. It must have at least one drainage hole at its base which stays in contact with AQUATHERMAT.

  • Seedling or cuttings tray as well as multi-cell trays.
  • Pots of 7.5cm (3 in), Model AZE with 2 levels of holes, including 4 in the lower one for capillary rise and 4 on the upper level for draining purposes.
  • Trays: the bottom must be open so as to allow the base of the container to touch AQUATHERMAT directly.

 

SUBSTRATE

It is vital that the heating of the substrate be regulated at an optimal temperature for cultivation. This typically means that the control is achieve by using a probe in the substrate.

High-quality substrates optimize capillary action and maximize the efficiency of the AQUATHERMAT system. A mix which contains more than 50 % of sphagnum peat ensures excellent results.

  • A minimum of 30 % (ideally 50 %) of sphagnum peat or coconut fibers.
  • Avoid materials whose particles are too fine (less than 0.25mm) or too crude (more than 10mm).
  • The substrate's water retention capacity can be increased by adding a wetting agent to the irrigation water (10ppm).

If irrigating by spray, surfactant agents must be sprayed on the anti-root layer so as to ensure instant water penetration.

 

FERTILIZATION

Algae-based liquid fertilizers and fish emulsions should be avoided. For plants with well-developed roots, it is recommended to reduce the usual amount (up to 50 %). All other types of soluble fertilizers can be used with AQUATHERMAT.

 

IMPORTANT! - PESTICIDES AND GROWNTH REGULATORS

Growth regulators and pesticides should be used sparingly. Systemic pesticides applied by root absorption (sub-irrigation) as well as those having considerable residual properties are to be avoided with AQUATHERMAT. Foliage application of pesticides is the recommended method provided within the norms and recommendations of your agricultural engineer.
