"This is an older study but the science doesn't change much. They are doing a larger system but the info applies to all systems. I highly recommend you check this link out. Do you have the link to the McMurtry and Sanders info?"

"I agree with Vlad and would go with a Hybrid system where you have media beds keeping all of the nutrients in the system with feed rate 10-20 grams/m2 of plants.  Rackocy developed his system as a way to deal with fish waste from an Aquaculture…"

"Has anyone considered using the bladder from the 5 liter wine box? You can pulled the spigot out and fill them with water and plug it back up and then freeze the bags. You can easily reuse them repeatedly."
