well i ordered some they are $1.80 or so each not $1.80 per bag, but seems they are used widly by professionals ie large green houses and such. Ill let you know if they live up to the hype. it would be very conviniant. im going to put a sting line above my plants and light on each side and clip these things all over it. so weh i need support i just strech the hook out and clip it on the plant. just hope that the tension is not too much.
