I am not too sure of the pump brand I will have to find out. Yeah the roots are getting adequately sprayed I am sure of that. For a while I thought maybe they are being over watered. I just moved them into the holes that are getting less spray so I will see how that works out.
edit: tried to free the roots up from the pot in hope they would grow vertically instead of horizontal, they aren't catching on to anything, but it's becoming a struggle to put the plant back in the system when I take it out due to the thickness of the roots growing vertically
