a bag of 50 RapidRooters costs about $12, cheap enough ... when rooted well, you can then stick the entire plug into either soil, or bury it into the hydroton/higromite, etc., for hydroponic setups ... as the plant grows, the rootball grips the hydroton, etc., very firmly, I've had no 'tipping over' problems, even with 6-footers ... :thumbsup:
