Reservoirs
A hydroponics Reservoir or Nutrient Tank is a crucial component of your hydroponics system. The reservoir stores the water and nutrient solution that plants require for healthy growth. It allows the nutrient solution to be actively or passively delivered to the growing plants. Size requirements will vary from different types of plants and how often you want to refill your reservoir, general guidelines for choosing the size of your reservoir :
Small plants – At least 2 litres of nutrient solution per plant
Medium plants – At least 6 litres of nutrient solution per plant
Large plants – At least 10 litres of nutrient solution per plant
