Hydroponics and marijuana

Hydroponics is a soil-free method of growing plants based on the use of a substrate and a nutrient solution. Using the substrate, the top of the plant is anchored in the cultivation tank and its root system develops in the nutrient solution or air.

According to online weed doctor growing cannabis in hydroponic systems is a fairly common cultivation method, especially in the commercial cannabis industry. The finished product grown this way is commonly referred to as hydroponics. Quite often, many inexperienced growers separate the concepts of hydroponics and marijuana, thinking that they are two different kinds of finished product made from cannabis. Like cones and hashish, for example. But in fact, they are one and the same finished product: cannabis cones, just made by different growing methods.

The benefits of growing cannabis in hydroponics
Cannabis does not expend vital energy searching for water and nutrients as it does in the ground. All of its power is directed to the development of the above-ground part of the plant, which has a positive effect on growth rate and yield;
The amount of nutrients the cannabis gets can be strictly controlled by the solution. As a result, it receives exactly as much nutrients and minerals as it needs for rapid and healthy development; There is no possibility of marijuana absorbing harmful substances that may be contained in poor-quality soil;
If there are problems with the plant, caused by a lack or excess of nutrients, it is always possible to quickly change the composition of the nutrient solution without the risk of damaging the root system. This cannot be done in soil;
There is no need to work the soil. The place of cultivation will be cleaner, and the grower will not have to carry the soil and pick at it.
Steps of hydroponics cannabis cultivation
Planting the seed
Cannabis life in a hydroponic system begins after the seed has germinated, when the sprout has grown to 5-7 cm. Germination is done either in the soil or immediately in the substrate. The second option is more favorable. It eliminates the possibility of stress in the immature plant during transplanting from the soil. When the sprout reaches the required size, it is placed in a special container, the hole in the bottom of which allows the roots to freely develop in the nutrient solution.

As a substrate, it is best to use vermiculite, as it is good at retaining moisture, as well as the necessary substances and trace elements for life. The container can serve as an ordinary pot with holes in the bottom, the main thing is that the substrate does not fall out of it, and the roots can grow freely outside of it.

The pot is placed over a reservoir of liquid, from which the plant will receive the necessary substances for life and development. The source of light for the plant can be any type of lamp that is suitable for normal cultivation in the ground. LED cannabis lamps or 600 to 1000 watt DNAT lamps are the best. It all depends on how many bushes you are planting.

The vegetative stage
During the vegetative stage, nitrogen must be predominant in the nutrient solution. It is he who will stimulate the growth of the plant. In second place go phosphorus and potassium. In even smaller quantities should be present sulfur, calcium, magnesium, iron and other elements.

It is very important to maintain a favorable pH level of nutrient liquid for cannabis during the vegetative stage. It should ideally be between 5.5 and 6.5, and between 5.8 and 6.0. Because they absorb nutrients from the liquid much faster than from the soil, they need to have their pH levels measured at least twice a day. The light regime at this growth stage should be set to 18/6 or 20/4.

Flowering
When it has grown enough to get to the flowering stage the light regime should be set to 12/12. If you have an autoflowering strain, it will flower by itself and you do not need to change it.

At this stage, the plant will need an increased amount of phosphorus. The proportion of nitrogen is reduced to the previous value of phosphorus. The amount of content of all other elements remains the same. The pH level is maintained at the same value. Nutrient requirements may increase during the flowering phase, so you will also have to keep an eye on conductivity – EC. This determines the concentration of substances and minerals in the solution, so that it can be kept at a stable level. The optimal EC value for cannabis is 0.75-2.0.

Preparing for Harvest
A week before harvests, to improve the taste of the finished product and eliminate bitterness, it is necessary to “wash” the plant of accumulated fertilizer in it. This can be done in two ways:

Immediately drain half of the solution, and pour water instead;
Pour only clean water into the solution during the last week.
Harvesting
Harvesting cannabis using hydroponics is no different than harvesting it using a normal harvester. We recommend turning off the lights for 24 hours to encourage the resin production of the plants in the dark. The bushes are then cut off as a whole, or as individual branches or buds.

If the shrub is pulling strongly upwards, vermiculite or fine sand should be added to fix the plant well, as well as to increase the level of light. It is the lack of light that causes cannabis to start to stretch out. You can simply bring the lamps closer to the plant, but so that it does not get a heat burn;
The temperature of the nutrient solution should always be between +16 and +21 degrees. If it is too low, the plant will get stress, if it is too high, rot will appear on the roots;
To increase the level of oxygen in the nutrient solution, you can use an air pump;
Air humidity should be between 40-60%;
The container with the nutrient solution should always be closed. This will prevent mold in it and debris from getting inside;
The solution in the tank should be changed at least once a week;
The substrate should always be moist.
Necessary equipment for growing cannabis in hydroponics
A closed reservoir for the solution;
A pump for watering, if the system is to be automatic;
A timer to control the light regime;
Compressor;
Air pump;
Lamps;
A device to measure pH and EC levels.
