Calling this method is the most advanced it would not be entirely correct.Even the ancient world knew how unfounded the cultivation of fruit and ornamental plants.One of the seven wonders of the world - Hanging Gardens of Babylon or floating plantation medieval Aztec - this is the modified today hydroponics.The damage from the production of vegetable products using chemical solutions are widely discussed in the society.This method has both ardent opponents and supporters clear. What is hydroponics?Harm and benefits
As already stated, it is a method of growing plants without soil using a non-nutritive solid substrates - expanded clay or any mineral fiber - and nutrient solution composed of 99% water and 1% of the trace elements.Hydroponic systems vary by device and scales from home mini-greenhouses, industrial buildings, but the basis is always the same method: using a liquid supply plant roots all the substances that are commonly found in soil.But unlike ordinary conditions not only external.If the soil is not enough of those components or plant can not fully remove them from the land, they are all in a concentrated and pure form are present in a solution which works and hydroponics.Damage caused by the culture in this case is minimized, because access to it is limited to pests and diseases present in the soil.However, consumer scares the other side - the chemical composition of the working solution, which, of course, goes to the fruit.What experts say about it and the farmers who have already introduced hydroponics?
harm is much less than when grown in open ground
So say people in the know, but ordinary consumers some assurance enough.As proof of his innocence experts cite the following reasons:
- Growing vegetables, herbs or berries on your site using the minimum protection chemicals and food additives, can not rely on environmental cleanliness crop and forget about the soil, poisoned sewage, chemicals, car exhaust, acidrains.Unfortunately, there is not a clean environment.
- without some share of pesticides and fertilizers can not count on the harvest, then the owner brings his hands into the soil synthetics.Because otherwise can not avoid such troubles as fungal diseases, rot, late blight, mole cricket and so on.
- in hydroponic solution of chemicals is not greater than usual feeding open ground, and trace elements are necessary for a plant it in pure form and in optimal doses.Because of this it is possible to obtain pure crop to the same period of reduced vegetation and maturation.
When hydroponics - harm and obvious evil
Yes, there is such a moment.The fact that the call narkosrede hydroponics pot grown in this manner.It would be surprising if such a progressive method of someone not used for criminal purposes.This drug is obtained in this way is much stronger than that of a conventional set of wild hemp.And if you write and speak about how the drugs act on the body, what consequences is fraught with addiction to them, in the case of hydroponics level of damage increases by an order.
Hydroponics own hands
for growing vegetables, berries and ornamental crops in a limited number (for family or for a small business) it is possible to build a hydroponic installation on their own with the minimum of cost.If you need very small amount of planting - up to 50 bushes or less, you can do the usual plastic pot with a hole that must be inserted into the larger containers of liquid.As a substrate suitable expanded clay, perlite, coconut fiber, and even the usual foam.Breeding and liquid dosage - strictly according to instructions supplied with the nutrients.If conditions permit, it is best to collect artless automated system for water circulation.The most expensive - a small electric motor.The device for the location of the plant can be made to the banal simple.Sold the right amount of plastic sewer pipes with a diameter of 15 cm with all necessary fittings and transitions.They are cut jigsaw round holes a plastic cup on the bottom of the soldering iron which is doing several small holes to pass the solution, and penetrated the roots of plants.It is necessary to take care of light and wait for the harvest.
