Today I bought my first hydroponic system - an Atami Wilma Big 9.
It's already in place in my 4 x 4 tent, under a 600w dual spectrum HID with a 6'' RVK rhino fan/filter.
For those that don't know let me explain that the Wilma is a 140lt reservoir (48'' x 45'' x 22'' - like a child's paddling pool), with a 'floor' that fits over the reservoir, where the 9 x 18lt Pots stand. A Maxijet 1000 pumps fluid from the reservoir through tubing directly into the growing medium (clay pebbles in my case) within each individual pot.
I will mix my tap water and nutrients (canna A&B) in a 10lt container, take levels for pH and EC. Adjust where necessary. When correct I will pour it into the res ten litres a time.
AIR STONES.
When reading others opinions about hydroponic set ups (I believe they are sometimes referred to as 'Hempy's'?) occasionally I have read about 'air stones' being kept in the reservoir....
What are air stones and what purpose do they serve?
