Soilless plant growing

When you hear “soilless growing,” the first thing that comes to mind is sterile laboratories with perfect rows of lettuce. In reality, this often means dirty rubber boots, constant fiddling with pH meters, and situations where overnight droppers become clogged with sediment from unfiltered water. Many people still confuse hydroponics with aeroponics, but the difference in root zone management determines everything from installation cost to crop growth rate.

Basic methods and their pitfalls

We once took on the task of installing drip irrigation for tomatoes in mineral wool. It would seem that the scheme was worked out - but after a week the lower leaves turned yellow. It turned out that the drainage was insufficient and the salts had accumulated to a critical level. I had to urgently wash the substrate, losing two weeks of growth. You can’t read such moments in textbooks - only in practice do you understand that any little thing like water quality or temperature changes at night can cancel out the calculations.

Aeroponics is a different story altogether. I remember how they tried high-pressure sprayers in a greenhouse near Voronezh. Result? On the second day, the nozzles began to clog due to small suspensions in the nutrient solution. I had to install additional filtration - the same system fromShandong Linyao Intelligent Agriculture Technology Co.,Ltd, which we learned about through their website https://www.lyzhihuinongye.ru. Their engineers specialize in selecting equipment for specific water conditions.

Not everything is simple with expanded clay either. It would seem that the most predictable substrate - but if the fraction is small, the roots begin to suffocate. I had to combine it with perlite, although this was not initially included in the project. This is where experience comes in handyShandong Lingyao Co.,Ltdin the design of hydraulic systems - they immediately offered an option with drainage mats, but we then decided to save money.

Equipment: What Really Works

Modern control systems are not just watering timers. For example, in projectssmart agriculturefrom the mentioned company use EC and pH sensors with automatic correction. But even this is not a panacea: once the pH sensor gave a reading of 6.8, and the manual measurement showed 5.2. It turned out that the electrode was covered with a film of organic additives. Now I always keep spare electrodes and calibration solutions.

Filtration is a separate headache. Sand filters are good for open systems, but if you are working with a closed cycle, a multi-stage system with disk filters is better. By the way, the website https://www.lyzhihuinongye.ru has detailed connection diagrams - this was just useful for me when upgrading a greenhouse near Kazan.

People often go too far with lighting. Expensive LED panels do not always provide an advantage - 600 W HPS is enough for seedlings, if you maintain the spectrum correctly. Although in multi-tier installations you really can’t do without LEDs, especially whensoilless cultivationmicrogreens.

Nutrient solutions: myths and reality

I still feel confident that it is possible to use a “universal recipe”. from the Internet. We tried it once for cucumbers - we got an imbalance in calcium at the stage of active fruiting. Now we always do a water analysis before preparing a solution, especially in regions with hard water.

Chelated forms of microelements are not marketing, but a necessity. Iron is especially important: in an alkaline environment it quickly precipitates. Once I had to completely change the solution in a drip irrigation system due to rusty stains on the pipes.

Organic additives in hydroponics are a controversial issue. We tried humic acids - they really improve stress resistance, but they clog the droppers. I had to switch to foliar treatments, although this increased labor costs.

Practical cases and mistakes

The most expensive mistake is underestimating water preparation. In the Rostov region, due to the high carbonate content, it was necessary to urgently install a reverse osmosis system. Projectintegration of water and fertilizersfrom Shandong Lingyao just includes such solutions - it’s a pity we didn’t contact you right away.

Here’s a good example: a farm near Moscow introduced drip irrigation with substrate moisture sensors. Water savings - 40%, plus it was possible to avoid waterlogging on cloudy days. The system was designed taking into account the recommendations of their technologists - the samesmart agricultural parks, which are written about in the company description.

Voltage drops became an unexpected problem. Conventional stabilizers did not help - we had to install frequency converters. By the way, in the list of equipmentShandong Lingyao Co.,Ltdjust therefrequency automatic equipment— Now I understand why they include it in the basic configuration.

Prospects and limitations of technology

Groundless methods are not a silver bullet. For grains they are not economically feasible, but for green crops they are ideal. Especially in urban agriculture where compactness is important.

Today I see a trend towards hybrid solutions: for example, drip irrigation in a coconut substrate with elements of aquaponics. But this requires serious engineering solutions - exactly what is proposed in the projectshigh quality agricultural fields.

The main thing is to avoid fanaticism. Sometimes it is easier to use an improved soil mixture than to fence a complex system. But where precise control and predictable results are needed,soilless plant growingtruly irreplaceable. Especially with modern equipment, where automation takes over routine operations.
