Water Temperature soil grow

This has been a random thought that crosses my mind every now and again. What, if any, are the repercussions of not letting water get up around 60 degrees. What if you are using a filter and its cold out and the water is like 40° and u just go and start mixing nutrients? Or what if u left your jugs in a basement over night to distill and the water is cold from being down there? should your water really b that warm if going in soil? Does it induce shock, or stunting? Hurt micro biology?

Thanks

cold water slows metabolic activity of microbes to a halt and stunts roots, both of which slow plant growth; thermostatic aquarium heaters are cheap and can keep your water 68-72 with their internal thermostats. that's what i do all winter when i'm oxygenating and dechlorinating water; just throw one in the bucked when i start the bubbles and when i'm ready to use the water, it's right in range.
be easy,

im a basement grow in Mi. its winter here, and my 24/7bubled, 33gal water res/holding tank is 69-71* year round. and with no heater.

Thanks for your 2 pennies
