Water temperature

How cold can the water be in a hydroponic system? I want to try growing a few plants in the river this year just for an experiment.

you usually want the water below zero, if at all -4 degrees

are you sure? in hydroponic systems its usually fairly warm...

75 F
24 C
he was just fucking with you

75º is kinda high temp for hydro.

68º or less is best,
to maintain higher oxygen levels
in your nutrient solution.

The type of hydro system you are using
will determine the max temp that is allowable.

DWC needs cooler temps,
than Flood and Drain tables.

I stand corrected. Earl is correct.
