Hi, I too am new to dwc, but have huge plants. I use 3 18 l oxypots and 3 rubbermaid clones that hold 20 liters. A couple of things:

1) do the plants really mature faster?

2) do you have to change the water regularly, as half the liquid is replaced weekly anyway

3) I use canna aqua and it costs a bloody fortune, with rhizotonic, flora and veg a and b, cannazym, cannaboost. Any cheaper options that are also good?

Thanks
