leaving the pump on all the time

[Tim]

Hi Ron new member here. I have finished your 11 pod garden and got my tomatos up and running.
There growing way fast. Got a ? about the pump for the nutrient, I have heard that leaving the pump
on 24 hours a day is a lot less stressfull on the pump and you don't save much $$ on electricity.
Would you sujest leaving the pump on all the time or cyculing it ?
