Congrats on getting your tilapia moved in. That's a great feeling, isn't it ? !....

I've read where others have said, the veggies do better as the system ages. I hope that's true. Mine are growing slowly. It has been pretty cool for FL....how's your weather been in CA ?

I'm not sure about the spraying. I'm wondering also.....Since I'm using modules, I can lift each plant out of the growbed and spray them, if needed.
