Finally, and equally as important as the previous steps are that the pH levels need to be maintained at the optimal level. Frequently adjusting the levels as they react to the incoming nutrients is a standard procedure that needs be done regularly.
More complicated hydroponics methods automize most of these processes with state-of-the-art technology that specializes in growing without soil.
Nutrient deficiency in the plant can be avoided by always using the correct amounts of mineral elements and following the specific nutrient mixing procedure when preparing the water for the main tank.
One of the most important aspects to consider when growing cannabis hydroponically is that the roots also need a regular fresh supply of oxygen.
The roots of the plant hang with freedom thanks to the lack of soil. This enables the upper part of the root system to have a continuous and fresh supply of oxygen. The bottom part of the roots is always exposed to a nutrient solution allowing the roots to expand with freedom and the plant to feed.
The term hydroponics is relatively new, but the growing technique of replacing soil-based systems with nutrient-rich water goes as far back as the Hanging Gardens of Babylon.
This calculated and efficient blend of nutrient-rich water needs to be switched out and replaced with a fresh mix at least once every fourteen days. In the meantime, the plants are usually flushed with pure water as the system is leached of any unwanted remaining water. Leeching the system with straight pH balanced water also removes any build up of toxic salt.
For this reason, the last crucial part of any basic hydroponic growing system is an airstone. Once connected to an air pump and placed inside the main water reservoir, the airstone creates dissolved oxygen with its bubbles that help provide more oxygen to the roots of the plant.
Additionally, this method of growing plants also has a substantial amount of eco-friendly advantages over more traditional growing techniques. In most cases after each harvest, soil depleted of its natural nutrients is usually replaced or heavily fertilized. This is a colossal waste of resources that creates more pollution.

Flowering time: 8 weeks
Grow difficulty: Difficult
Indoor/outdoor: Grows well both indoors and out. Its dense buds can make it susceptible to bud rot when humidity is high, making it ideal for drier climates if grown outdoors. OG Kush is a good choice for indoor grows as well, especially if training techniques are applied effectively.
Strain overview: OG Kush is a famous hybrid strain with a somewhat mysterious backstory. What is known is that OGK offers a euphoric high that is also calming and sedative. The smell of OG Kush is earthy and pungent, and the buds blossom with resinous crystals. Long before legal dispensaries came around, OG Kush was already a household name in the underground cannabis industry, cherished for its reliable quality and balanced high.
This article is presented by Advanced Nutrients, a global company raising the bud weights and reputations of cannabis growers since 1999.
Grow techniques: This hybrid is susceptible to powdery mildew, but pruning will improve airflow in the canopy. It’s a great strain to grow indoors with SCROG or SOG methods to increase yields and bud size. Always support the buds as they can become extremely heavy and dense. A hydroponic setup indoors can help keep the immune system healthy and strong to prevent against disease.
Climate: Can handle colder nighttime temperatures and prefers lower humidity levels while flowering. Ideally, OG Kush plants are kept at temperatures between 65 and 80 degrees Fahrenheit.
Feeding: OG genetics require heavy feeding with calcium and magnesium. Make sure plants are receiving enough food in flowering to allow the buds to develop to their full potential. Feed plants with compost tea to strengthen their immunity against powdery mildew.
