Space compost
I found out what the tea is made from. We have a space compost pile and the tea is a liquid extract sucked off from the fermentation process. A Teflon lined Nomex wet trash bag is filled with various food scraps including leftovers from our fresh produce that arrives with every unmanned Russia Progress resupply spacecraft. Composting is OK because these bags are specifically designed by NASA to hold our wet food trash; a wet trash bag by any other name is just a compost pile. Only in our case we are particular about what goes into the wet trash bag. The high sought after scraps in Gardener’s compost includes fruit peels, garlic-onion skins, apple cores, paper scraps, and a pinch of Kazakhstani dirt that was stuck to the side of a whole onion from Baikonur. When kept moist, the contents stay warm to the touch and after a week or so turn into a semi-liquid mash. I think the dirt added an essential bit of planet Earth to make the organics ferment into the “compost tea”. It tastes sour to my roots but provides me with the necessary nutrients to survive.
