We are currently researching how to create an organic system.
Is it possible for the system to completely rely on liquid fertilizer feeds of a fish product (made up of minced and cooked pest carps found in our aussie waterways) seaweed fert and worm juice?
How much would you recommend per 1 litre of water?
Also we have unlimited supply of decomposed granite. Would this be a suitable to use as as part of the growing media?
Many many thanks for your help and advice Emily
