With values of pH and EC suitable we get a high quality cannabis grow.
It is very important to know the pH and EC of the water when watering and fertilize our cannabis cultivation. If we control it correctly,
we will ensure that plants assimilate all the neecssary nutrients and have an abundant production of high quality.
Marijuana, like people, also has its PH. This term insurance that sounds but perhaps we are not quite sure what that might be. Well, the pH stands for Potential of Hydrogen and is the measure of acidity or alkalinity of a solution. The scale of PH is divided into 14 points, PH 7 is considered as neutral pH, above 7 and up to 14 will be PH alkaline and acid 0-7. Surely sounds like the most is the neutral PH which is the skin of people and is 5.5, as we see in many bath soaps.
The PH indicates the index of alkalinity of water, ie, making the nutrients can be absorbed by plants. Ideal for marijuana cultivation pH is between 5.5 and 7. If the pH is below or above these figures, we can put a lot of nutrients in our plant, it will not be able to absorb them.
The marijuana plants, like humans, have its variations of PH and as stable is this substance the plant will grow better or worse. According to its PH marijuana will be more or less healthy because this substance is one that regulates the entry of nutrients to the plant. In addition, the PH in the cultivation of cannabis may also vary depending on the substrate used. If we cultivate the plant with organic fertilizers and natural soil you may have less control over the PH if used in its cultivation mineral fertilizers.
To help control pH variations we can use fertilizers and pH reduecrs or enhanecrs.
The good water for growing marijuana on soil is one that contains a pH between 6.5 and 7.5. If we cultivate cannabis using mineral fertilizers should be more careful in controlling the pH of the nutrient solution.
Products we can help control the PH
In the market we have products that help us to have the optimum pH for our plantation. The PH-Grow / Bloom and PH + is a reducing and increaser pH for nutrient solutions.
PH GROW is suitable for reducing the pH in the growth phase and PH Bloom for the flowering phase of the plant. PH + is a potassium hydroxide solution and is used to increase the PH.
The PH Down is another product PH regulator, which makes the company General Hidroponics and serves to lower the pH of a nutrient solution. In addition also it contains nutrients needed by plants of marijuana. It can be used during growth and during flowering.
EC or electroconductivity
If the PH indicates the index alkalinity of the water, the EC (acronym for electroconductivity) indicates the level of water conductivity.
The EC is the ability of a liquid to transport electricity (that is, the amount of salts dissolved therein). The more fertilizer has the water, the EC will be higher.
Water alone is not conductive, so it is, we must provide minerals. EC values that are appropriate for the cultivation of cannabis are those with a variation and mong 0.60 to 2.00 mS.
There are electronic meters to know level of EC we are using to water our plants. These meters are few electrical devices that calculate the conductivity of a liquid.
If we are watering our plantation with tap water, we keep in mind that if you have more than 0.4 the EC should reduce with distilled water or rainwater to that value. But maybe the water we use is equal to or less than 0.4 therefore we can add a fertilizer without having to treat it.
The EC amount of water also depends on the geographical area where we are.
