That’s a neat setup you have there!
Thanks! I used to call mine hydroponics but I read that if it’s hydroponics the plants are usually hanging with water flowing over the roots. Aquaponics is when the plants are planted in pots in water, or bare root, and actually submerged with water flowing over them. Both work great with tomatoes since they naturally like water. I put the lattice over them to keep the plants out of the water as they grow. Both ways are same in principle.
