Water temp differences when changing water

How much of a problem will it cause if the water I use to refill my bucket is significantly cooler than the water I am replacing? My basement is currently ~57f, which is also obviously what temp my standby water is because my water source is a bunch of 4 gallon culligan jugs I refill at various grocery stores. My DWC plant is still a seedling, so that tent is kept at 73f. Should I make the effort to warm up my water prior to changing it out? I assume the worst thing that could happen if I don't is some stunted growth.

If it's too cold i'd warm it up by sitting the water in the tent overnight or add boiling water, I'm not familiar with Fahrenheit 18/22c is the recommended range from canna.

Ok, noob question: I assume it would be ok to mix the nutes prior to warming in the tent overnight, yes?

i wouldn't let it get to 73F. change it out when it's about 65F.
I just checked and even though my tent is at 73, my water was 64/65 and that was after a few days. the caveat is that my seedling light is a blurple and I only have the blue light on so it's not that intense. I fully expect the bucket to heat up more when I flip the "bloom" switch or move it to my auto/veg tent.

I also had a temperature deficit, you could try putting spars/grill/mesh etc under your bucket so it's not touching the floor and air can get under it, it'll help with temperature, heat is naturally lost to the floor.

Now i have my buck placed so that the dehumidifier catches it with warm air.

do you use anything to prevent rot? if your temps are 64/65 all the time, that's pretty great. but i'd still use something just in case

I'm gonna wait until I get it under my full light before worrying about the water temp of the bucket. My main concern now is the temp of my change water, which has already been assuaged.

No dehu needed for me right now lol. Ambient RH in my basement will be between 15-30% until spring. I can stick it in front of the space heater though.
