I pour a couple of tablespoons of bat guano in a half gallon glass jar. I then let it 'cook' in the sunlight for a couple of days.

Then, if I want the straight tea, I strain it and use only the liquid.

For prolonged useage, i simply shake it after it cooks and pour it straight in the plant soil.

It leaves a slight silt on the surface, so, subsequent watering will again leach ferts.

Since flowering, I have switched to shultz cactus ferts.

But, still the tea is used now and then.
