[ STRUCTURE ]
The LABORATORY GARDEN is a small garden next to my tiny house, which consists of several segments. Protected from rain I put several separate small gardens in terrariums under a small roof to test and compare the cleaning activity of various concepts, plant combinations and soils that are present in the internet to find the optimal solution for the recycling of used water in a mobile tiny house. The concepts are examined not only in terms of their efficiency but also their practicality and cost/benefit in a mobile tiny house. The question is: Is it a good solution for water recycling in a mobile tiny house?
I would like to know if certain water treatment plants have a positive influence on each other and if the soil quality contributes significantly to the efficiency of the plant sewage treatment. The topic „soil quality“ plays a prominent role because I would like to find out whether normal, freely available soil from the forest offers the micro-organisms a good environment as well and thus can provide the same performance as in the trade available. With this I go to the points 5-9, which I have defined in the focus.
[ THE GROWING GARDEN PROCESS ]
When the six plants of the first garden grow I’ll divide and implement them in further test construction in several gardens. Gradually I add more combinations with another natural material in the laboratory garden. With the plants I have a filter available that satisfies the points 1-9 in focus.
This laboratory garden will exist for over 1 year to test the efficiency of each model through all seasons of a year. I will regularly analyze the water and publish the values here on my homepage. The laboratory garden can be visited during the OPEN HOUSE and there you can also exchange knowledge with me.

[water recycling with water treatment plants]
On 06 | 01 I started with a small selection of six water treatment plants in a terrarium- Phragmitis communis/austral. | Schilfrohr; Iris pseudacorus | Wasserschwertlilie; Typha latifolia | Breitblättriger Rohrkolben; Acorus calamus | Kalmus; Scirpus lacustris | Flechtbinse and Juncus effusus | Sumpfgras. These plants are in a small garden and form the beginning of a laboratory garden, which will gradually grow with further test models.
The aquarium has been donated and is an upcycling piece that I have equipped with a hole for a tap to take a sample. The drainage on the bottom is filled with coconut fiber to filter out small sand particles. The soil is free accessible soil from the forest. I was looking for special soil from an area with coniferous trees.
[water recycling with sand, active carbon and gravel]
The laboratory garden is growing. In February 2018 I developed the Garden 2 according to the concept of P. Franchino. In the book „Ökologisches Bauen“ by the authors P. und M. Krusche, D. Althaus and I. Garbiel is a concept described which work without plants to clear the used water.
This system can be used to replace the revision chamber. The filters can be connected to a heat recovery system and the water can introduced into a sewage plant system.With the concept of P. Franchino no plants are used. The grey water is cleaned over a bucket equipped with a strainer and connected with a second bucket until it is clear again.
I’ll build a small garden according to the idea of P. Franchino where I can take water samples to test the efficiency of this concept.
The questions are:
Can this structure also remove tensides?
Which contaminants exactly are removed?
How long does it take to clean the water?
Is this system useful for a tiny house?
I wrote an article in the WIKI where the exact structure is explained. Below you see the prototype of the garden.
