water temps for soil

should I worry much about the temp of the water I water with being to cold? I grow 12/12 from seed and I've read somewhere to use colder water during flowering , don't know if its one of those bad unproven tips that floats around but the idea was the rains colder closer to harvest , so I never worried about the water being to cold for my ladies already flowering but what about the younger ones ? Seedlings and month olders...
my cab stays fairly cool 75 lights on 65 lights off ,
water temperature is probably between 55-60 don't have a way to check it but will get a way if i should be concerned with shocking little ones

how ever cold it is coming out the faucet should be good enough. I really cant see how cold water or warm water would make any differance

55-60 is on cold side for sure. slows growth. also should not go cold for flowering until final flushes.

In nature, Senescence is when plants begin to die. plants have instincts when cold water hits roots. they think it is late fall and winter is coming, so they will hermie to procreate. natural response. some are more sensitive and will not hermie, but why take a chance?

great way to purple up a plant though. I would stick to mid 60's or higher. get an aquarium heater if you must

my water sits to dechlorinate , and that is a horrible answer if i was a complete newb

when room is 66ish water will be 60-64 ish if a large quantity.

you wanna stun ya plants

then delay for up to 7 days, as they try to recover

then expect to harvest on time later

go ahead but you won't get both,

always always use air temperate water

thats why the big boys allow it to sit 24 hours before use,

it also evapes off any(Cl)

root shock is something thats considered advanced for many noobs..?

avoid at all costs

thanks for the reply , I definetly do not want to shock or delay , my water sits out in 1 gal jugs for 24-48 hrs with airstones and the room there in stays around 65 ... So I should be ok ?

should be, but get an aquarium thermometer from walmart. 2$

I no longer aerate my water, but prefer to allow it to sit,

any bacteria or sourness is handled by the actual pouring of the water

or the aeration of poring it thru a sprinkler like a watering wand they're great

water wands are a secret to themselves lol.. just connect it to your 10 usgallon water tank

you do have a water tank...? lol

hah thanks for the tip , though I'm too small to need those I only use a gallon or two every other day , small personal cab grow O_O

Between 65 and 72 is great. Under 65 and you slow your roots uptake metabolism. Above 72 and you encourage vector growth, especially bacteria.

Definitely keep temperature differential between day and night temps to less than 10 degrees, so tighten that up. Greater than 10 degree temperatures encourage Downy Mildew, Powdery Mildew, and fungus growth. Unless you like that kind of thing. Slime Mold is pretty cool. ;P

sorry but I have never had a problem watering straight out the tap. I dont have time to be fucking around letting water sit around and getting the perfect temp. The roots are experiencing the water temp for what, maybe 5 minutes before the heat of the room brings the dirt back to normal.

What I might believe would affect the growth is if you could keep the dirt colder for days as it would be later in the year in nature. Its not just the rain thats colder later in the year, its the ground too, in the wild. I suppose I'll just keep shocking my plants, because they finish in the same amount of time as most other strains.

69F is the agreed upon water temp...after much debate.

my temps at lights off to 17-18c amd on its 24 I find water was taking longer to evaporate so I stuck a small fan facing the soil and break the top of the soil every day or after watering untill all is dry.
It helps for my case but an idea for your case
And I have no other means of warming my bottles of water apart from sticking em in the bath and that's a mission of its own lol. The point is my water going in is about 18c and plant's are not bothered especially after aiming my second fan to the soil and breaking it up

Big boys use RO water. Clean, pure and dependable.

The bottom line IS that cold water WILL shock the root system and slow the plant down for the week that V mentioned.....

Don't water with cold water and don't water with hot water... It's not just common sense!

Growers with flaccid peni,

use RO water, then have to play catchup

adding the very same minerals (Mg), (Cl),(Zn) etc etc

that they just ripped out

go figure?

Like yer buddies in the joint?
We all get flaccid at the thought of you V..until you open your mouth..

RO contains nothing. You add a minor amount of Ca/Mg as a buffer for use in all hydro applications.
IF, you use a "quality" nutrient. It has all those other things in it that you took out of the RO.
Now there are not "extra's" that will limit the uptake of all the other good things the proper nutrient has....I.E. the plant will now use the "more" available nutrition to grow faster and larger ...... E. Rosenthal, G. Green and a host of others say so!
So does actual; science....

I wouldn't change back if I was paid to.....
I control exactly what is in my water.

I've SEEN it for YEARS - Any hydro style run with RO will out yield any tap water run I have EVER seen!
If your water is 150 or more ppm from the tap. You SHOULD run RO! The actual results speak for themselves...
