hmm im not sure about the tea bags, but maybe some small pots, ive even hear of people and seen pics on this site, of plants grown out of whole 2 liter bottles, but you dont want your roots to be exposed to too much light or it harms it/kills. Id prolly just go with some regular pots, large, or small. if its small you might need to tranfer them later but it could be easier for sproutlings. anyways good luck and hope you get fat buds peace
