Hydroponic Deep Water Culture
I cannot seem to find info on what the ideal water temperature should be set to in a DWC. I plan on growing lettuces and spinach. Thanks for your help.

It depends on the plant and your local conditions.
You want to keep the water between 65F - 80F, but as you are growing cold weather crops, aim for the lower end of that range to prevent bolting.
