HOW TO MAXIMIZE CANNABIS YIELD: WATER SCHEDULING AND WATER QUALITY.

Cannabis Sativa production usually takes place in a plant-soil-atmosphere continuum where all variables in the system can be controlled to achieve maximum yield.

The cannabis is grown in the controlled environment planted in coco coir; the best substrate optimizes root growth through a perfect O2 to H2O content relationship. On top of that, you can control the temperature, humidity and thus the evaporative demand.

Furthermore, you can control the type of irrigation, type, and amount of nutrients supplied through the irrigation water. This article aims to empower you to reach exceptional yields by focussing on the amount of water supplied to the root zone and irrigation water quality.

AMOUNT OF WATER SUPPLIED TO THE ROOT ZONE TO MAXIMIZE YIELD.

Two dripper lines in the grow bag are preferred, especially in warmer regions. In general, light irrigations more often are chosen with an increased amount from just before the heading stage up to harvesting. Some research on field trials is available, and it would help to read it.

A little overirrigation is needed to wash excess nutrients out of the root zone. A built-up of nutrients can negatively affect the adsorption and availability of other nutrients to the cannabis plant. Measuring the Electrical Conductivity of water draining out of the bags will give you an indication of the amount of overirrigation needed to get rid of salts building up in the coco coir.

WATER QUALITY THAT WILL ENSURE EXCEPTIONAL YIELDS.

Coco coir is nearly inert, but if your irrigation water might not be up to standard and if you haven’t done it yet, you should do a lab test to ascertain the quality of your water source. More information on the level of concern for certain elements can be found in this article.

Excessive amounts of mineral salts in your water source can influence plant health negatively due to nutrient antagonism.

Check the following information to determine and increase the quality of irrigation water.

1. Ph of the water.

The Ph should be between 5.5 and 7.0 to be neutral. A Ph below and above the neutral range will inhibit the availability of certain nutrients, leading to a nutrient deficiency in cannabis.

2. Electrical Conductivity(EC) and Total Dissolved Salts (TDS).

These two metrics are closely related but are not the same, yet anyone can be used to indicate water hardiness.

Ideally, the TDS should be below 200 Parts Per Million (ppm) with an Ec not higher than 0.4 EC.

ENRICHING THE WATER WITH THE REQUIRED NUTRIENTS.

To ensure optimal leaf growth, heading, and overall vigorous growth that will result in maximum yield, the right fertilizer mixture must be chosen to add to the irrigation water.

A continuous supply of these nutrients in the irrigation water as needed during the different growing stages will ensure exceptional yield.

Understanding the nutrient needs of cannabis is essential to ascertain that no fertilizer burn or malnutrition of the plant can lead to reduced yield and Return on Investment.

Care should be taken that the correct amount of specific nutrients are supplied to the plant during the different vegetative stadiums of the cannabis during the growing season.

CONCLUSION.

Testing irrigation water to ensure the best quality is an essential first step you should take when you want to grow cannabis with exceptionally high yields. Irrigating the correct amount of high-quality water enriched with nutrients will ensure that the plant has adequate access to needed nutrients in the irrigation water.

Overirrigation is required to get rid of excess salts but must be monitored to ensure that nutrients added are not wasted. By applying the correct amount of high-quality water mixed with the needed nutrients, you can be assured of excessive yields and Return On Investment (ROI).
