i just put 1 bag in my 2 1/2 quart water container and just keep replacing the used water until it doesn't even have a tint of color from the tea bag.Then I start all over again.
I used to make tea from the bag then make a second batch from the same bag to use for watering.I got lazy and just started doing it the way i posted above.

Just out the bag in cold water? Doesn't it get to strong if you let it sit in there a few days at a time?

I grow a lot of plants at a time.A couple quarts of water doesn't go far...I have to add water to the tea as I go along or it wouldn't be enough tea to water them all at one time.
It gets diluted really fast.
I start 300 or so plants at a time 2X a year and I seem to have something new sprouting all the time.
Here I can grow year round.
