Water for orchids. A few words about how we prepare the water and on the regulation of PH.

tuman   Most of our orchids we grow to semi-hydroponic method.
We prefer the term semi-hydro.
Here is the article about this method.
In this article let’s talk about water. About how we prepare for the water solution and spray of orchids. And just a few words about the regulation of PH.
In this fog live orchids in nature.

Let’s talk about water.

Rain, fog. High humidity. All this water is fundamentally different from the one that flows from the tap. You may watering with this water may be home palm and from orchids may be banal hybrid falaenopsis from Dutch greenhouses, but it is unlikely that some species.
This means that water must be prepared.

What is poured on top.

If you do not take into account the acid rain and other trash and waste products of our enlightened civilization, the rainwater is practically distilled. A fog condensing on the leaves is distilled water. Repeat, rainwater almost distilled. Almost. The fact that the air there is always dust that is soluble in water. And when the water runs down the trunks, then it somewhere that will flow from the leaves, rotting in the fork of branches, then by bird faeces. PH of this water 6.8 – 7. It contain very little salt solution, microscopic quantities, but they are. And here you can make two conclusions:

  1. Must fertilize at every watering, but very small quantities. That is, the salt should always be in solution. Information on the solution can be found here.
  2. Water must be prepared.

How to prepare the water.

In the literature, you can meet the recommendation to use a mixture of distilled water (80%) and water from the tap (20%). Or, more commonly, water after filtration through reverse osmosis filters.
That is correct.
But if you have several hundred plants, these methods are very expensive.
Distilled water road. Distillation column to buy – expensive. Osmosis filters, when such consumption must be changed every couple of months, but it is also very expensive.
Tap water dirty, and usually rigid. Her PH (in our tap) 8-8.5. It has much salt Ca, Mn, Mg. This is something that falls bloom in the teapot. That is called a stone. That raid – the death of orchids. He will score the velamen, score the stomata and the orchid will die.
Conventional coal-fired household filters are not bad to cope with a stone. Unless, of course, often change. A pitcher, in which they are inserted, very comfortable to use.
Known following fact. Peat, lain long enough in the water, it softens. And if sphagnum peat, it still adds to the water for some, not very large, number of antibiotics and “Fulvic Acid”. Fulvic Acid – this is the end product of the process of humification. Acid, rich in organic and mineral substances in a readily accessible form for plants, is an organic growth stimulator.
And so, that’s what we’re doing:
1. We miss the water from the tap twice through a carbon filter.
2. We insist on peat for two – three days. 500 grams of peat in the tank to 30 liters of water. Peat change once a month.
It remains to tweak PH and add fertilizers. The fertilizer solution recipe is here.

Regulation of PH.

To control the PH you need first and foremost instrument of diagnostics PH. You can buy a very expensive PH-meter, or you can use much cheaper ph_test_kitPH test kit.
So should have two solutions ph_down1PH down и ph_up1PH up.
With these tools you can easily set the required values of PH of your solution.

Аssembling for making water for orchids.

Here with the help of such things we prepare the water. How it’s made, you can read here.
