How much water should be used when watering a 5 gallon bucket. I assume about 2 but I just want to be sure.

Not sure there is a definitive answer its all what the plant needs.

So basically when it gets dry water it more, right?

Basically yes

i water my 5g with 1g of water each time

Sounds about right snake....how often do you water and what type of light are you using...are these for your mothers?

Exactly, depending on the lights and the size of the plant it could vary greatly. Depends on how much evaporates and how much the plant drinks. I've found once a wekk works pretty good and sometimes I water twice a week, you shouldn't need to water more than that.

couple liters

3 might b too much

yeh the only thing that matters if your factoring in plant size, is how often your gonna water no matter how much water you give it each feeding. 1 full gallon of water for a 5 gallon bag is just fine, and youll water it more than likely every 3-4 days. My plants are pretty thirsty, 2 days after each watering they get a little growth spurt in them, which means that theyre searching for more moisture in the bag, and stretching their roots out to find it. I give it two more days beyond the spurt to dry out the soil. This has happened every single time i water without exception, and itll continue to happen through flowering, only the buds will swell rather than the plant get taller and bushier. I use 3 full gallons of soil, and i only feed my plants about 3/5 of a gallon every time, and i still need 4 solid days between waterings.
