i know a grower who knows a grower who germinated some seeds and planted them in small containers, then transplanted the visibly sprouting ones into larger containers. but he realized he was running out of soil so (being slightly broke and not wanting to look suspicious as fuck going to wal-mart for potting soil in the middle of the night) he reused some of it without picking out the apparently non-viable seeds. two weeks later, one of his potted plants has five tiny sprouts in perhaps a 4x4-inch area next to it. so now this particular individual is wondering whether these would be worth the trouble of transplanting into separate containers, or whether the risk of harming the main plant would be too great. the other option would be to keep the main plant and the healthiest (or indeed, femalest) looking accidental plant. all of the others are one per pot.
