Another way to use GHE’s nutrients !
Another way to use GHE’s nutrients !
Here is a completely original use of our FloraNova grow and BioSevia. For a few months Frederic, our technician, has been in contact with Bruno from Kanopee Design, a company specialized in creating and selling terrariums.
Bruno wanted to use our nutrients to produce two wet tropical terrariums. Here is his feed back:
“The dosage I used corresponds to the recommendations you gave me, ie 1 ml / liter. In both cases the nutrients are distributed trough a spray system I designed.
This system operates at an average pressure of 10 to 15 bars. A diaphragm pump generates the pressure on the fluid stored in a water tank, and is then conveyed through a polyurethane tube and pressure fittings, all the way to the injectors which atomize the nutrient solution into fine droplets of about 60 microns with a spray cone of about 80 °.
The spraying system runs automatically in cycles that vary from a terrarium to another depending on plant variety and desired climate.
Usually cycles vary between 10 and 20 seconds at intervals of 2 to 3 hours, and the system is turned off at night.
The water we use comes from reverse osmosis.
The water supply is different and is adapted to each nutrient.
For FloraNova, the reservoir is an opaque 25 L glass tank with a pump that insures continuous mixing of the nutritive solution.
A drain was installed at the bottom of this reservoir to supply the diaphragm pump.
For the terrarium using BioSevia, the solution is “more complex” because of the double components : BioSevia + BM. The tank remains a 25 L glass reservoir where we also placed a BioFiltre. I changed and removed the biofilter’s motor as it was too noisy for me. I also installed a submersible pump at the bottom of the reservoir to insure several operations, like nutrition and water circulation within the biofilter, oxygenation of the solution with bioballs, and permanent mixing of the nutritive solution.
A drain is installed at the bottom of the reservoir and provides power to the diaphragm pump + a level sensor that detects the solution’s level and controls the Siemens PLC providing complete management of the terrarium
(spraying cycles, lighting, heating, ventilation, waterfall, humidity). The fogging system is identical to the system used with FloraNova.
In both cases the nutrient solution distributed in the terrariums is not recycled: one part evaporates naturally from internal climatic conditions inside the terrarium (temperature of 26° to 28° Celsius and humidity fluctuating between 70 and 100%). The second part is recovered in a waste-collecting reservoir on the side. This allows keeping the solution free from debris and impurities that could clog the sprayers if it was used again (even with a good filtration.)
Now about soil and substrate. My goal when I design a decoration is to give it relief and reproduce a landscape as close to reality as possible. The basic support I use to create these volumes is polystyrene, which is cut and wrought to the desired shapes.
This basic support allows the application of a waterproof food resin on which is projected sphagnum peat. This substrate creates an acidic substrate with good water retention, especially favorable to the development of tropical water mosses.
All the plants I use (bromeliads, neoregelias, ficus, begonias, ferns etc.) are installed as epiphytes on this support. I also include into this scenery exotic wood (mangrove) and natural cork.
Since we transferred these two structures to GHE’s FloraNova Grow and BioSevia Grow for testing, I noticed significant improvements of vegetative growth:
• A very significant re-growth of bromeliads and Neoregelias with appearance of numerous suckers and larger aerial roots.
• A densification of biomass, especially on tropical species like begonia, ficus, pilea, and asplenium.
• A very strong deep green coloration of plant tissue.
• The root systems are much denser.
• A rapid and dense growth of tropical mosses.
