Wait... am I understanding this correctly? You set up a self sustaining system for growing that uses your naturally made fish poop??? That's fuckin brilliant. I dunno why it never crossed my mind but makes perfect sense. I wonder if it could handle marijuana. ...
Yep. Aquaponics. Lots of info and videos out there. It can totally do MJ. You just gotta get the balance right. To be honest, it would not be a simple garden for mj. If I did it, i would do it outdoors with big tilapia or Pacu. Definitely cycle up the garden with lower fish number and leafy greens for a year... then add more fish and mj. Shit would get stinky indoors though. I suppose a carbon filter might help..
Some guy on RIU journaled an indoor mj aquaponic system... maybe 6 months ago...
you know, not sure why, but there has never been much interest in aquaponics around RIU. Not sure why.. I started a few threads a few times, but, they never went anywhere.. Just some "cool" "that's neat".
My aquap setups are leafy greens and herbs... low nute needs...which means i can keep lower fish stock...which means much fewer headaches.
The more nutes needed, the more difficult it will get, in general. Low nute need setups are stupid easy, effortless really.
If you wanna produce fruit you need lots of fish waste being efficiently broken down to plant food and keep the plants growing/consuming consistently.
Lots of checking Ammonia, Nitrate, Nitrite levels. A pond test kit covers these and more.
