Growing lettuce in aquaponics is very easy and a good business opportunity for anyone with a small amount of land. Most of us know how to grow lettuce in conventional hydroponic farming, but in aquaponics, the process is very different. The water used in the system will be used to feed your plant. It will contain fish waste, organic matter, nitrates, and bacteria.
It will also be filtered. The filtered water is then pumped into your growing tank where it mixes with a solution of growing flowers in aquaponics water and nutrients.
nce the plants start to grow, the nitrate level in the system gets reduced because of the oxygen from the roots of the plants. This causes a depletion in the ammonia that is naturally present in the water.
This is when you will have to fertilize the plants. The most important thing is to make sure that the plants are fertilized correctly. If you overfeed the plants, they will get sick and will not produce good-quality lettuce. This is why you will want to make sure that the nutrients you are using for the plants are the correct ones.
