How to water marijuana plants

marijuana watering schedule

Watering is by definition the action of spreading water on a surface in order to benefit plants. In our case, it consists of distributing water on the surface of the substrate or cultivation land.

Watering the plants in your marijuana crop is the action or work that will be repeated the most during the cultivation, so the ideal is to do it the best you can.

Water is the vehicle for transporting nutrients into the plant and is responsible for distributing nutrients ( carbohydrates, vitamins, hormones ) for its metabolism. In addition, it dissolves the nutrients that we contribute to the plant, moistens the substrate, provides oxygen to the substrate and roots, maintains the pH of the substrate, etc…

Knowing the correct way to water is as important as knowing when to do it. If you do not water your marijuana plants when they are touched, they will become dehydrated, and if you water them excessively they will drown due to lack of oxygen in the root, that is why you have to find a fair balance.

Since watering is the most repeated action during cultivation, try to offer them water with a low concentration of salts (the ideal is osmotic water ), since unwanted salts can block the roots and prevent the correct absorption of nutrients. If you use tap water we recommend the frequent use of enzymes to avoid accumulation of unwanted salts.

HOW TO WATER YOUR MARIJUANA PLANTS CORRECTLY

Important factors when watering:

1. Water in a controlled way:

Marijuana, during its vegetative growth stage, needs small cycles of humidity and drought:

The small cycles of drought and humidity allow greater aeration of the substrate, thus favoring a better development of the roots and the metabolism of the plant.

Before watering you must observe that the substrate is not waterlogged, since it must be kept aerated. A permanently wet or waterlogged substrate lacks the necessary oxygen for the roots and favors the proliferation of pathogenic microorganisms harmful to plants.

 Watering when the substrate has lost some of its moisture stimulates the growth of the roots, as they grow more as they move in search of moisture.

 Since the root is the main nutrient-receiving element of the plant, it is essential to maintain an abundant root system to be able to water and fertilize in abundance, since on the contrary you can easily drown or over fertilize the plants.

 During flowering stage the cannabis plants should have developed an extensive root system must, therefore cycles of drought and humidity are not as necessary to stimulate growth; it can be watered more often but always avoiding that it is continuously humid. Being the largest plant during the flowering stage, it will have a greater capacity for absorbing nutrients and waste.

2. Use quality water:

If you use contaminated water or unwanted salts, your plants will not progress properly, which is why the quality of the water is a very important factor.

Let’s say that on a water quality scale, osmotized or distilled would be found first and with higher quality, mineral mineral water second, and tap water third.

If the water tap has a concentration of salts (EC) high, as is the case with most water in the home network of cities, it is a very good option to invest in a filter osmosis with them will remove suspended matter and much of the chlorine. Chlorine makes the water drinkable and keeps swimming pools clean because it kills microorganisms. Using chlorinated tap water does not kill plants, but it also does not promote symbiosis with fungi and bacteria beneficial for marijuana.

You can use enzymes to largely prevent unwanted salt buildup on the substrate and roots.

If you irrigate with water from a tank, it is very important as well as economical to use a diffuser stone with a small air pump to oxygenate the water. There are also CO2 and oxygen tablets to introduce into the tank and better the contribution to irrigation water.

3. Check and regulate the pH (acidity of the water) and the EC (concentration of salts):

Both if you contribute nutrients to the irrigation water or if you are going to carry out an irrigation with water alone, it is important to know the concentration of salts that the water contains, since it will largely determine the state of the plant.

It is very important to regulate the pH of irrigation water (between 6.2 and 6.5 on crops substrate ground ) after adding the necessary nutrients, since the pH of the water will determine the pH of the substrate.

In hydroponic crops it is important to maintain a pH of 5.2-5.5 for proper absorption of nutrients by plants. An unregulated pH in your hydro crop can make you lose your plants in a few hours.

4. Water slowly and spread:

Water slowly and in a balanced way in the amount requested by the plant, if you water too quickly the water will drain from the bottom of the pot without getting the substrate wet.

In nature, water reaches plants mainly through rain. The beneficial rain for crops is that which falls soft and constant, allowing the ground to absorb it and disperse it. This is what you need to imitate in your marijuana cultivation.

The water follows the water, when it falls in quantity it does not penetrate but runs across the surface, it does not distribute homogeneously, it draws nutrients and erodes, that is why if you water slowly allowing the water to be absorbed slowly, the nutrients will remain in the substrate otherwise you will drag them like in the root washes.

It is better to water your crop in two “rounds” than to water your crop plant by plant until the end, since this way you will ensure greater water absorption.

However, it is good that the plant partially drains the water that we apply to it, since in this way it will release unwanted salts.
