My feeding water is 14C (57F). It makes me wonder how low is too low for watering plants without causing stress?

It's coco.

If the water is to cold the plant will tell you.. it will react and become droopy like it needs water..
that being said.. plants prefer water temps closer to room temps or 70f..
let your water set and warm before you use it..

Dissolved oxygen (DO) refers to the volume of oxygen that is contained in water. Oxygen enters the water by photosynthesis of aquatic biota and by the transfer of oxygen across the air-water interface. The amount of oxygen that can be held by the water depends on the water temperature, salinity, and pressure. Gas solubility increases with decreasing temperature (colder water holds more oxygen). Gas solubility increases with decreasing salinity (freshwater holds more oxygen than does saltwater). Both the partial pressure and the degree of saturation of oxygen will change with altitude . Finally, gas solubility decreases as pressure decreases. Thus, the amount of oxygen absorbed in water decreases as altitude increases because of the decrease in relative pressure (Smith, 1990).

Not sure about soil but I refill my res straight from well and it can get as low as 50 with no apparent stress, just keeps on going. I keep res temps at 66 and they are quite happy, no drooping:).

i had my hydro clone unit @ 45 f before ! the heat was off in the room i did not know it they were all loving it grey huge roots and very fast most healthy clones i have ever had . 55 f and higher . i am not sure if you can go lower with out stressing there bigger plants . just get another bucket and fill it with water let the room temp warm it over night before you use .

But you might be unique. I have to consider other opinions too. Trying to guess the opinion average so to say.

I hear ya and not at all offended :) I search out the best answer as well. If I had a choice I would run same temp in as I keep res but it's a garden shed and no hot water access.
