I have made teas for years to fertilize my garden. I use two 45 gallon drums and rotate so there is always one ready. I use stinging nettles, horsetail, lawn clippings and willow water sprouts that has many growth hormones. All I do is put some greens in the bottom of a barrel and fill with water, cover with plastic and let it sit in the sun for 3 days or so. It's really fragrant and I keep it far from the house. I dilute the tea 10 parts water one part tea. Does great for my garden. I have a 400 square foot garden and fertilize at least once a week. It's good practice not to use chlorinated water to make teas unless you let it sit open for a day.
