Dear friends,
Greetings! I hope you are staying healthy.
Long story short, so much has changed in what have been doing. IAVS has been substantially modified and improved. We call it IAS now, Integrated Aquaponics System! IAS - the art and science of growing more food organically, with much less water and energy.
You can grow fish, microgreens, greens, herbs, vegetables, fruits, fowls and small livestock using IAS methods.
Here is a very brief video for you to have a look. Based on your response, I will elaborate.
Kind regards, vkn
