does cold water hurt plants?

I'm growing in soil, indoors. Should I prepare the water the night before by letting it sit in buckets and adjust to room temperature?

it is additional stress so yes to a small degree, it might interrupt constant growth because of the stress, too cold and it could even kill them(seen people water with ice cubes and this happened). and yes thatd be preferred, id throw the buckets in a hot water bath if they need it really bad though.

I grow in soil what I have is a big container that can hold about 100l I mix up say 30 litres add my nutes the I have a air stone in it and a little pond pump and I just connect a bit of clear tubing to the pond pump and pump the water to the plants like a hose the water is nice and airater and the nutes r nicely mixed

my plants likes warmish water
I use dry nutes so need hot water to mix the powder, then add cold water to get it about 70 F

I measure the temp with a digital cooking thermometer, as I feel with hempy the proper temp is important

have you ever measured your temps?

From my understanding plants should be watered with room temperature water. Cold water or hot water can shock the roots and stunt growth or slow growth. Not sure to what extent however.

No. Here's why -- Water that has been left standing will retain little of the dissolved oxygen within. That oxygen is important for the plant so you want more dissolved oxygen, not less. Also, go with room temperature water right from the spigot. Too warm or too cold water can stress a plant. Avoid.

Here's an OG trick to help when watering. I put a tiny drop of Dawn detergent into every gallon of nute-water I make up, veg and flower rooms. The detergent makes the water finer so it spreads out more. In effect, Dawn allows the water to form smaller drops in the soil and that is a good thing.

Good luck, BigSteve.

I don't know how much sense this makes bc everyone rave about how good collected rainwater is and to collect rainwater you usually collect it in a big drum which would sit out for days if not weeks and months. I'm not trying to argue, just wondering how you explain how so many people love rainwater...

In my state it is illegal to catch rainwater, as the runoff is taxed!

Our new governer won and promised to remove the tax however. It gave him leverage really.

People are hooked on anything that appears "natural". Problem is that natural doesn't mean pure. There are times when the rainfall in the northeast is extremely acidic. Using that rainwater untreated would not be good for plants.

Water that sits for hours loses oxygen. Oxygen is a good thing for plants. Judge for yourself and do what is best for the plants, not your self-esteem.

Good luck, BigSteve.

Letting the water sit over night will remove any chlorine. I use a 20 gallon reservoir with a small pond pump set up to pour the water back into the rez similar to a fountain. Bubbling it would also be good.
I used to store water in one gallon milk jugs. They would sit for up to 3 days and never became "stale" or anaerobic.

what temp do hydro guys like to keep their res??? bout 68f
I stay at about 68 and then when it warms in may area I drop a bit to help keeping the ladies cool...

my rule of thumb is: "If it too hot/cold for you its too hot/cold for them"

that's what I did with my water when I grew in soil. if I forgot id do it a few hours before the lights come on so it has time to regulate..

Aerating would take care of this problem for you.

Have you ever been in a nice cozy shower and gf flush the toilet?
Or jump into a cool pool on a hot day?
Same difference. It doesnt "hurt" you per say, but damn that was cold...

Think of it this way, if you grow a plant outside and it rains... is it hot? Not really, it is usually a lower temperature and plants act completely fine to this. If you are pouring 35 degree water into your pots you will for sure have some issues but if you do anywhere from 50-70 you won't have any issues. Anyone who tells you otherwise needs to grow some plants outside.

I leave water sitting out for days to help disipate chlorine, and I have never had any problems from doing this.
