Nutrient temp?

Well, what happens is that the outside (or room) temperature will be around 50 F or 10°C as well (a bit higher though). And I'd rather be concerned with that fact

In case outside temperatures are getting low and the nutrient temperature drops to (let's say) 15C/59F or below, one may consider heating the nutes up to 20-22° C with a 10 bucks aquarium heater.

What will happen actually when nute temps (and/or outside/room temps) will drop under 50 degrees? Nothing fancy, the available oxygen in the nutrients will increase somewhat but the general metabolism and uptake of plants will be much lower, - until stagnation.

PS: with low temperature of nutrients the EC should be higher to encourage osmosis.
