On June 10th the Aquaponic Group will meet around 13:00 (1 pm) at the Van Gendthallen in Amsterdam to build a small system as a nursery for fishes and plants seedlings. Also we're going to work on PH value of our first small systems and the four-bed one.
Fishes/plants nursery and PH values
DIY Aquaponics Building Weekend #7
We have already built three systems, now it's time to dig into some important aspects: how to control Ph values? What is a good plant fertilizer?
