Once I've known your channel, I've been watching them. Lady few years, I've been learning so hard on fermentation and Permaculture here in Sydney. I totally agree your way to raise your fish farm and keep teaching us how to respect our Mother Nature. I'm wondering I'll come back to hkg in Oct for a week, will it be possible to pay you a visit please? In the meantime, where can I buy the equipment you showed us in this episode please? I've been trying to search up locally, but Jo success. Thanks for your great effort on every aspects in helping people and hopefully your next project will happen soon.
