Backyard Aquaponics
A place to discuss aquaponics

half barrel growbeds are nice, but they don't use space very efficiently
cut horizontally instead of vertically you can fit 2x as much gb in the same footprint just about..

? The available area would be pretty much the same wouldn't it? Except cut horizontally you end up with a tub that is significantly deeper than if cut vertically in half and laid on their side to form more of a tray. Besides, from what I've read so far you don't gain much advantage of GB's over 12 inches deep.....but then again, maybe I'm a little confused.

My understanding was that the SOP was to cut them vertically and lay them on their sides.

people have cut the blue barrels both ways...
you mentioned putting this in a gh, and deeper beds are definitely better (more filtration)..
some folks use 100gal rubbermaid stock tanks that are around 22" deep.. good filters
