I have a 6' x 1.5' geo pot bed. I hear ya as far as wanting to get the lower section air. That part takes the most abuse. I built a frame on casters for mine. Pushed a piece of roof valley down below it and used it as a drain pan(pics in my builds album).

lol i put my first 4x7 on 4 heavy duty 3.5" casters. it cracked the middle of one of the long 2x4s after about a month. my second 4x7 went on some 4x4 risers and is rock solid. i dunno why i thought i was maybe gonna move the first one. i cant move it anyway its like a thousand lbs. i just let my runoff evaporate off my concrete floor, i try to only have a little every now and then. but thats a good idea for a larger drip pan.

You can't move the 4x7 hey...? My long bed moves. I doubt it ways 1000 lbs. but I hear ya. If I was to do a 4x7 or 8 frame I would have to put a center stiffener in. I also would put in a steel rack. Like that stuff they put in concrete. I used a white wire shelf from target or something. Keeping that bottom supported while airated goes hand in hand. As far as a drip pan I would just slope something like currogated steel for a big bed like that. It seems you got it working for you. I'm just scoping some big floor plans lately and am thinking mobile raised beds would be niiice.

yeah man the idea of mobility was appealing, but when i get right down to it, the only reason i would ever move them is to paint the floors. and i can just slide a roller underneath them either way. when they are empty and bone dry i might be able to roll the one on wheels if i had help. i cant use my left half very well so it might have something to do with that. if you do go with bigger rolling beds do yourself a favor and put a set of casters in the middle too. an obvious choice in hindsight, i know.

also i have 2 layers of chicken wire under the first bed i made, second one has steel fence. either way, nail the top edge of the fabric into the top 2x4. every 12-18" all the way around. its necessary

Nice. Saving this one. Been tossing the idea around of getting into dirt beds

[Kozmo]

Nailing/Stapling the fabric in is sound advice my friend. Have not thought of that.

Some Good info here

Is the material you are using for the bed's liner landscaping fabric ?

[nameless]

its similar to landscaping fabric. the geo pot material is heavier and slicker.

i'm in for this one. good info so far
