Cheap DIY Air Pruning Pots *aka* smart pots

[zappa66]

On my last trip to Kmart I ran into this great stuff, its a non skid rubbery mat/cloth type stuff. It easily folds into whatever shape you need and comes in many colors (I'm looking at the dark green and brown, nice and stealthy for outdoor use). I am thinking of doing largish beds out in the swamp, and might have to do one for the veggies too.

Damn I just through out a bunch of that stuff. Nice thinking on your part. About how big is that pot? Would that stuff hold the weight of about a 5 gallon container? I guess you could reinforce it with some chicken wire or something..........................................................

~4-5 gallon

Hi,
Those look great. Have you been using the new pots for a while, or is it a new invention? Like, have you seen root-pruning and does everything work ok?
Thanks for the idea.

Not to bag on your invention but to merely voice a concern. Is that material that fake rubber type material? I would *personally* be worried about the rubber/plastic leeching into my plant. Not that this will happen, just keep it in mind.

 

[zappa66]

spanishwilly: nope just put it together the other day.

Dank-j: I have some soaking in some water for the past week, can't see any discoloration or anything like its leaching. I think it would be hard to tell if its doing anything. To be honest I'm not really that bothered but its something to think about.

looks like the stuff you put in a cabinet or tool box to keep your stuff from sliding around..

how did you close up the bottom...or did cut a circle for the bottom and wire it to the upper cylinder?

 

[Spanishwilly]

It's safe

It's safe

Dude, it's the stuff they sell in restaurant supply shops to put on a tray for your glassware after it's been washed. They don't slide around then.
It's foodgrade material. It doesn't bleed or leach anything. It's safe to put into an industrial dishwasher. You don't want your medium to touch plastic?

P.S. I think I love this pot for coco.

Nice!

I saw the official smart pots the other day and was thinking how to DIY them.

Glad i found this. I'm gonna try this for my moms.

i think its a great idea but might be to flimsy for my taste.i might somehow add some type of rigid support just to ease my own mind

 

[bengie187]

thats a pretty sweet idea

First I wired it into a tube, then folded the bottom like a paper shopping bag. You can see from the pic. I used wire to hold it all together.

Man, I'd love to do a coco ebb and flow with smart pots out in the greenhouse for veggies...

With the folded bottom and full of soil it seems sturdy enough, I might really sew the pot with wire all along the edge if you're making a large heavy pot.

i thought about using these plastic laundry hampers with holes all in the sides, not sure how strong some would be though

 

[Leviathan]

i like the bottom tub, u could actually cut the top half off of it and make strips which u could then use to make more rows down the middle for air prunning to occur on two sides for a few sections, and it would still be deep enough. thx for the idea-

WalMart has wire mesh trash cans in office supply. They're metal though. Don't know how good that would work.

nice tip zappa66

I think by the time I did that, it would be more money than just buying an
Air-Pot, wouldn't it? How about making a tube (or even square walls) out of hardware cloth to line it? I think that might even be rigid enough to not need a base/floor. HEY... SQUARE AIRPOTS...
Someone else has some pretty sexy homemade Smartpots on a thread in here made from hardware cloth and landscaper's fabric. Zappa66's grip mat idea might be even better. I predict we are seeing the start of something that's really going to catch on here.
Thank you Zappa66

If they are securely fastened and won't fall apart when filled, I'd say they would be pretty sturdy without any additional support. No different than the grow bags I use. Once filled with soil, they stand up just fine. You just need to make sure the bottom is flattened when you set it down.

I was thinking of using stakes to make sturdy immoveable outdoor planters.

"sexy homemade Smartpots on a thread in here made from hardware cloth and landscaper's fabric"

Kind of like fisher15's planters in the outdoor section? That is what I was planing on doing but decided to give this stuff a try. The landscaping fabric HAS been proven to work however.

Edit*
has anyone thought of using reusable shopping bags? look like they might work if they don't rot...
