Well-being of plants, speed and autonomy of irrigation
Ollas SPELEO Jamet® dedicated to large surface irrigation with the possibility of connecting them in series provides the following benefits:
- Optimization of the watering time = Time of filling/water supply of the OLLAS SPELEO mounted in series with pipes and fittings of Ø 40mm.
- Simplicity of assembly and use.
- Invisibility of the Ollas SPELEO and the connection system.
- Ease of maintenance of plant surfaces by allowing mechanical machinery to pass over them without risk of snagging or impact.
- Avoid the risk of theft or voluntary damage.
- Allows deeper rooting of shrubs and trees
- Suitable for vertical cultures in container or horizontal in the ground.
- Increased autonomy, thanks to the water contained in the connection pipes (Ø 40mm) of 1.25 liters of additional water reserve per linear meter:
- 1 day to 1.5 days maximum more per linear meter between 2 Ollas SPELEO.
- Depending on the length of the pipe between 2 Ollas SPELEO.
The Ollas SPELEO Jamet® with the possibility of connecting them in series, allow professional or private users to benefit from the same advantages as the ORIGIN Collection, namely:
Benefits for crops and landscaping
- Keep a cool and airy substrate.
- Mix low to very water-intensive plants in the same area.
Advantages in use
- Simplicity and comfort of use.
- Very high durability, does not fear frost or acid soils.
- Little or not sensitive to limestone.
- Save water and watering time
Major benefits for plant health and vitality:
- Biomass increase of at least 250% (noted by Astredhor Pays de Loire) and depending on the type of plant / soil / climate / frequency of watering, compared to watering by sparkling, drop by drop and watering can.
- Leaves not wet, less risk of disease by oomycetes .
- No stress or water suffering.
- If tap water is used, the chlorine has time to evaporate.
- Deep and homogeneous root development
- Better plant nutrition with more minerals and trace elements.
- Better plant health (more vigorous and disease resistant).
- Better nutritional, taste and organoleptic qualities for edible plants.
- Allows deeper rooting of shrubs and trees
9 months of research and tests in 2019 by Poterie JAMET to guarantee the technical qualities of ceramics, in accordance with the requirements of plant professionals, in particular for ease of connection in series and increased resistance at the neck.
Ollas-JAMET irrigation ceramics are registered with Inpi and their irrigation performance has been verified by ASTREDHOR Pays de Loire , technical center for plants.
Now producers, French and foreign cities trust us for the irrigation of places and subjects with very different needs... landscaping & vegetable gardens, container irrigation in Gramat (46), use in vegetable containers or in the ground, etc.).
Measurements by ASTREDHOR
The water and time savings provided by the Ollas-JAMET® have been measured by the independent technical center ASTREDHOR Pays de Loire 49, (National Association of Horticultural Experimentation and Demonstration Structures).
Irrigation tests, in 2021 for 6 months, by Ollas Jamet showed the following results compared to other irrigation systems (Sparkling, Drip, Watering Can, etc.):
- Increased biomass from 250% to +500%.
- 75% to 88% reduction in water consumption.
- Reduction in watering time 3/8 times faster depending on network installation and Ollas model
- Decrease in hooping (weeding) observed but not measured.
Tests in real conditions
The tests in real conditions, the methods and the results of the Ollas Jamet ORIGIN®, SPELEO® and MINI-GREENHOUSE® have been defined, carried out and confirmed by plant professionals, references in their respective fields:

Instructions for use / installation
- Make a hole of the size of the chosen Ollas + room for the vertical and horizontal connecting pipes.
- Wet the hole and water the soil around it, as for a plant. To be done once, only during installation. This makes it possible to quickly start the water conductivity of the Ollas action zone.
- Place the Ollas in the center and bury it completely with its pipes and connection accessories.
- For assemblies in horizontal series, provide 2 pipes of 40mm diameter to be placed vertically at the beginning and end of the entire network to be connected:
- 1 at start for water supply inlet
- 1 at the outlet for the evacuation of air during filling and as a water outlet indicator at the end of the filling of all the Ollas-SPELEOs connected in series
- Fill the Ollas-SPELEOs with water, through the water inlet/inlet pipe of the assembly to be connected. When the water spurts out from the other air evacuation rod/excess water outlet, all of the connected Ollas SPELEOs are full.
- Positioning: The spacing between the Ollas and the plants to be irrigated depends on the size of the Ollas, its radius of action (see the table of characteristics), the climatic conditions and the type of soil.
- Example: for a medium-sized Ollas No. 6, the spacing varies between 1m and up to 3/5 meters for creeping crops.
- Remember that the roots are always pointing towards the wet area.
- Increase the volume of the Ollas for a very dry climate, a soil favoring the natural flow of water and/or plants requiring a lot of water.
- Decrease the volume of the Ollas for a temperate climate, soil that retains water, and plants that don't need a lot of water or are intended for xeriscaping.
The Ollas-JAMET® are not afraid of frost, it is not necessary to remove them from their location.
- Do not fill them at the beginning of winter
- During the winter period, let your connected Ollas SPELEO network empty and do not fill it.
