I have started this indoors, but it seems to be growing very slowly. Any tips? I have about 20K lumens concentrated sort of red/blue CFLs (half soft / half daylight). I heat the water to about no more than 78 degrees F. I use a use FloraGro (2-1-6) about 1 cup for 15-20 gallons. This is a deep water culture setup.

All of these vines came to me in what I would describe as a bundle of dead sticks with roots. After some time the green buds started popping out.

Shortly after sprouting:
