In order to properly conduct the comparison, general parameters were used instead of optimum nutrient formulations.
This was key to achieve the beginner level grow simulation.
Various fertilizers were used throughout, including:
- General Hydroponics
- Advanced Nutrients
- Basic water soluble fertilizers available at home improvement stores.
During the vegetative stage, nutrient levels were maintained in the 600-700 parts per million (ppm) range.
During the flower stage, nutrient levels were maintained in the 700-800 ppm range.
The nutrient solution pH range was maintained at approximately 6.5 – 6.7 throughout all stages of growth.
