Learn to prepare and manage different types of nutrient formulations in hydroponics.
Plant nutrition in hydroponics not a fixed science. Nutrient formulas and working strength solutions are tweaked and fine-tuned throughout plant life cycle.
In this course you will be able to :
- understand different nutrient solutions
- analyse the components of a solution
- decide what is appropriate
