Shove- they are RapidRooters. Next time you are down 91, get off at exit 4 and go into Putney Village- Liquid Sun is right behind the laundromat across the street from Basketville and keeps them in stock cheap. They work awesome. IF I had to make a list of 'top 5 grow products I could not live without or cob up some other way', they would be right up there with calmag, pH indicator drops, and high-CFM blowers, lol!
