Growing orchids in semi-hydroponic. The first part.

Most of our orchids we grow to semi-hydroponic method.
We prefer the term semi-hydro.
On this system, its advantages and disadvantages of farming practices we discuss in this article.
Images in this article are used in our other articles.
Now let’s begin:

What is a semi-hydroponics.

First, what is a semi-hydroponics.
Hydroponics – a way of growing plants in a neutral and chemically inert substrate, when the plant receives the entire set of nutrients from the solution, rather than from the substrate. There are many different ways and methods of hydroponics, information about them can be found in the literature. We dwell on one particular method – semi-hydroponics
In this method, using capillary capability of substrate, nutrient solution from the reservoir at the bottom of tank rises to the roots of plants.
From the definition it is clear that the game is played with 4 components: the reservoir, capacity, substrate and solution.
First of all, look at them individually.

Tanks and capacity.

In the methods used, they are combined. If you deviate from the formal definitions – and the capacity of the reservoir – is the same.
It’s just a plastic cup, box, bucket, a jar of suitable plant size and regular shape with three holes at the height of a third or a quarter of the total height from the bottom.
The Regularity of form is important, all kinds of convexity in the walls of the pot will prevent capillary rise of the solution.
Material capacities, let’s call it potty training, is important. He must be neutral and inert, ie does not react with a solution, durable, resistant to light.
Many plastics are not resistant to sunlight. Many are destroyed under the action of salt solution and weak acids.
Perhaps the best pots is to recognize the various containers and packaging of a food. They are inert, racks, usually regular in shape. They come in various sizes. There are two properties are not unimportant – they are free, and reuse of plastic packaging helps preserve the environment.
This package from under the lettuce. Bottles of water, cola, various boxes and jars in which we buy food in shops.
That’s how we do the tank from the bottle of juice. In pictures. Well understandable.
This black piece – soldering iron. You can replace soldering iron with a hot nail.
All burrs cut.
Well, that’s ready.


Holes in the pot, as we have already mentioned are three. This is not just. In holes in the pot there are a few destinations.
Guaranteed level of solution – is not possible to pour more.
Ventilation, air intake inside the tank.
Are three rather than one, as one large – will fall out substrate. And three little – all at once will not close by particles of the substrate.
Diameter of holes should be slightly less than the average particle diameter of the substrate.
The holes are made on one side for two reasons – first: less disturbed tank stiffness and the second – which is easier when there are several rows of jars on the shelf, so it’s easier to notice when watering that poured enough solution stems from the hole.
