3 gallon pot, how much water?!?

Ain't none of you marijuana experts over-watering are you?

Heck I give my 6" pots a half pint once a week

My 5 quart pots get 1 quart

My 5 gallon buckets get 2 quarts to a gallon, this summer it's been taking about 6 days, in the winter might go over 2 weeks between watering
I treat soil like a camel. Only let them have water when they ABSOLUTELY OBVIOUSLY NEED IT. It forces those roots to stretch, forcing them to search for water. And I've also found that the roots are thinner, but 5X more of them. Make those haughty girls find the water.
 
What always works for me.

A proper watering session always consumes 25-30% of the pot size. So let’s say you’re using a 3 GALLON pot. A good slow soak 8-13 minute watering session, will usually cause the pot to absorb around 2-3 QUARTS with a small amount of run off at the end. (3-5oz).

My 4 gallon pots get 1 gallon each watering. 5 gallon pots get about 1.25 gallons.

The only thing that changes is the watering FREQUENCY depending on how the plant is pulling up water based on its size/growth rate.

Best watering practice is water SLOWLY and evenly, with 2-3 minutes inbetween to allow even saturation. (Think of light/medium rain in nature).

My watering session of 4 plants usually takes 19-26min.

Hey that is a VERY good tip. I'm gonna go do this now.

You must of been getting more runoff than what stayed in the pot unless your mix was 10 times as dense as mine.
What kind of dirt are you using?
1 gallon of water in a 3 gallon pot, with an established plant, is 2 or so days between waterings. Temps being reasonable
THIS is actually a pretty good answer. Most people go crazy with this answer.
An established plant, 3 gallon pot? About a gallon +/- about times a week and you're good (Sunday, Wed, Sunday. During veg??? Hmmmmm . Get it really wet, let it dry out, then wait a day.

I like this. Kinda like, I know I know, 12 autos in a 4x4. I just train the plant so they all have even canopy. And then just harvest the main colas. I'm not a big smoker, so I prefer multiple options, smaller amounts with dense donkey dick top buds.

Sorry, YES, good method, sloooooow. It takes me 3-4 hours to water 12 plants. But I loooooove it. It's soooo relaxing.

Early after transplanting- runoff occurs quickly
Once there is a good root mass- it goes slowly
I believe 25-30% of the pot size is generally good after a root system is established so in a 3 gallon pot- 3 quarts to a gallon each feeding
This is growing in coco/perlite mix in fabric pots- not soil

I'm in soil, 3 gal plastic pots and different growers are going to find a variety of ways to succeed.
I'm in mid flower, the stretch just ended and I have been watering 22 oz or less every day since flowering started.
I top dressed with 3 TBL of ff ocean forest 10-7-7 in early flower and will top dress with 3 tbl of happy frog 4-5-3 in about 7 days or so, other than that just the daily watering.
There are a number of reasons I choose this style.
A big one is fungus gnat larvae hate it. All I do is put up sticky traps and there are usually only a few that are caught.
