{ Week 8 } How Plants Receive Nutrients from Fish

My dad started a small patch of tomatoes a couple of years back using a similar technique to the video. Very primitive but similar ideas of using the tank of fish at the bottom as opposed to NFT which uses a nutrient film flowing into channels.

Natural Provider of Nutrients
Phosphorous, Nitrogen and Micro-minerals are provided by the fish waste as opposed to using Seasol or other fertiliser.

Calcium hydroxide and Potassium carbonate is also added. This also balances pH.
Sodium bicarbonate is a cheap option but sodium is not good for the system.
