We know that your biggest problem with an irrigation system is the fact that it gets clogged very easily when used in combination with products high in organic content. Consequences are:
No more flakes and foam!
Foam doesn't usually clog the system but indicates an imbalance in the nutrient solution or bacterial activity. Botch will affect plant growth and health.
The presence of biofilm can lead to several problems. It can restrict water flow and nutrient distribution, leading to uneven feeding. Biofilm can also harbour harmful pathogens that may infect your plants, leading to diseases.
Additionally, the biofilm can consume some of the nutrients in the water, altering the intended nutrient balance for the plants.
