CANNABIS WITHOUT SHORTAGE : pH

For a plant to assimilate the nutrient needs optimum pH, so we must take into account the pH of the water to water the plants.

The pH scale (1 to 14) measures the balance between acid and alkali. Thus, it would be very pH 1 acid while a pH of 14 would be alkaline (basic). Be a logarithmic scale to have a water with a pH of 5 is 10 times more acidic than pH 6. another with pH 7 is 100 times more acidic than pH 9 a.

The cannabis reacts better with a slightly acidic pH, but .... why ?.

Our plants assimilate the different nutrients in different pH ranges so in certain ranges can any of them (or more) are impossible to absorb by the plant.

As can be seen in the table, if we irrigate, for example, with a pH below 5.5 have clear gaps begin to nitrogen, potassium, sulfur, phosphorus even greater ...

Thus, if we want to give a completely assimilated watering plants, have to do with a pH close to 6.5 and preferably above rather than below. In hydroponic cultivation the pH can be lowered somewhat, to 5.5.

If we water with pH adjusted we are ensuring that we provide the nutrients can assimilate, Iron throw useless in large doses if the irrigation water pH is 7.5 for instance.

What to do to ensure that the pH of our substrate is appropriate?

Use substrates (preferably special for cannabis) who have already adjusted the pH (6.6 to 7 is fine) and we must also be aware of the amount of nutrients it contains to know more or less when we have to start fertilizing. The reason for using a soil pH adjusted basis is that in this way we will have soil pH (which is important) provided between the values ​​we try to have. It's useless to water with a pH of 6.5 if the pH of the base substrate is 5.5, and the resulting mixture will have a pH less than 6.5.

For the pH of the substrate, we have to take a representative sample of 10 g of substrate and mix with 250 mL of distilled water. Let stand about 5 to 10 minutes we can proceed to take the reading.

The best way to measure pH with an ELECTRONIC METER is as easy as soaking it and read the display.

Electronic meter pH and temperature

For a well-nourished plants without gaps as best you can do is prepare a good irrigation fertilizer pH adjusted.
