lol.. okay bro, again, how should I water? I have found many many many things saying that you water until the water pours from the drainholes.
Therefor I thought the difference was:
Flush = putting through 3 times the amount of water as your pot. Ie: 1 gal container = 3 gal water
Water = just water until all holes drain. This is easily doable with about a quarter gallon of water in a 1 gallon pot.
So... If you could please be so kind as to tell me about how much water I should use in a 1.5 gallon pot then I could be squared away with how you suggest to water.
