Here's a pic of my sump with a 1yr old Pathos, which started out from 3 small clipping, they're now over 7 feet in length and have been coiled several times. I've had to start trimming them as they're starting to get out of control. The second pic is my 3week old Bakcoy's. I'm currently trying to determine which one will grow faster, the one on the left with a constant drip or the ones on the right with roots fully submerged. The media I'm using to grow them in is a Hydroponic clay stones, which I've had success growing peas and various herbs using the drip method.
