I am thinking about trying micro aquaponics in my basement. I have a garden
pond that we bring the koi inside for the winter. I am running a pump in the inside
pond now anyway. I would use lava rock as the growing medium because of availability. Use 2-4 ft grow
lights. I would try to grow lettuce and spinach. This would also be a filter to aid the biofilter in the pond now. Any thoughts and ideas would be appreciated. Again this would be just small scale.
