Now now, lets not get mad, I'm sure we can settle this dispute:) You go to
that side of the room and GW go over to the other side.

I think folks will agree to this one. Once a cell quota is reached you
cannot get rid of it this way.

Well less GW cells taking up space and light. Does well in PC lighting.

Not without killing the plants along the way. Plants need more nutrients
than these LTRGT's or GW.
It's the same thing with algae, large algae need more nutrients, smaller
they get, the better they do at lower nutrient levels. The same thing
happens with plants. They have a much fast uptake rate than algae.

UV's are great also. Flip a switch and your done in a day or two.
