I'm in the market for some bubble bags. I want to use the trim from 4 plants. They are each 3.5 feet in height and roughly 2 feet wide. I want to run all the trim in one batch. Will this fit in a gallon bag set, or should I go with 5 gal bags? Which brands should I look at? I want something with average quality that I can use for a year or two (roughly 4 batches a year), that's reasonably priced.
