I believe by growing beds mjohns you mean for the Hydroponics?
I would be putting the Hydroponics in (around lol) the sump and the Pothos will be suspended along the entire back wall of the pond for efficiency as well as aesthetics.
Four foott wide leaves ample viewing space so I should be fine as long as the plants are concentrated along the back and sides.
Nic I was debating making a separate container just for the plants themselves much like a 2'x4'. Would this be more efficient?
Would it be bad if the roots of the pothos dangled in with the rays?
I will be going with a sump that sits above the pond as mentioned by rvrrays earlier.
My current liner was purchased from Lowes. It has alot of give to it and is textured to hold more benificial bacteria (which you can feel the layer of slime on it).
I think I will be going the same way for my new pond.
I would prefer to build my pond rather than buying a tub because I have access to all the materials I need (except the liner) for free.
A custom, finished and stained wooden pond is much more pleasing to the eye than a tub in my opinion
The whole thing is still in it's "fertilization" stage.
I appreciate all for your feedback.
Keep these suggestions coming!
