Is this the smart pot material??

[al-k-mist]

I dont want to post a link, but the stuff is called:
Dewitt 3-Foot by 100-Foot Non Woven 12-Year Landscape Fabric 12YR3100

And the description is:
DeWitt weed barrier 12-year is an easy-to-use, environmentally safe fabric that controls weeds before they start
The non-woven, hydro philic treated fabric allows air and water to pass through
Dewitt landscape fabric minimizes light penetration to suppress weed growth
Fabric is treated to minimize degradation due to UV light exposure
The design also prevents unraveling and makes the material easier to cut; measures 3 by 100 feet

We want to make giant ones for our organic greenhouse grow this year, and want to make sure this will work

No that os not the same. Smart pots are made of simple felt. Go to joanne fabric and ask for black felt made from recycled water bottles.

Thanks dude.
I think there is one a couple hours away, so Ill call em in the morning and ask them if they have it, if not to order the stuff

The Smart Pot is an inert fabric container that has no meaningful chemical exchange with the surrounding environment. On a microscopic, chemical level, the Smart Pot fabric is an inert plastic. If the medium and fertilizers you use in the Smart Pot are organic, you will be growing organically in the Smart Pot container.

In other words recycled pop bottles, nylon, etc

non-woven polypropylene... same thing as "green" "earth friendly" $1 a pop reusable grocery bags. find some black ones... and you have built in carry handles to boot... they're thin though... and get roughed up a bit after a long Outdoor season...

treated! with wot?

Hey al-k,
You can use pond liner/landscape fabric or industrial felt to make homemade smart pots. I'd use whatever's cheapest and most readily available. Or make a couple out of each fabric and see what type you prefer.

Heym inthegarden, whats up?
Thab=nks, we may do that...a trial run. if so we shall post it

I think smart pots and similar fabric bags are made of non-woven geotextile polypropylene fabric.

This fabric is used in the waste industry as a filter, allowing water to flow through the fabric and keeping the solids in the fabric.

The fabric is used to make giant bags that sit on a screen set about six inches off the bottom of an open top or closed vacuum box. Sludge is pumped into the dewatering box, the water drains out through the fabric, through the metal screen supporting the fabric, and into the space between the screen and the bottom of the rolloff box. There are threaded openings on the side of the box, as low as possible, where valves can be screwed in and couplings attached. That way the water drained out of the sludge can be pumped over to waste water treatment and after a couple of days, the sludge has no free liquids so it can go to a landfill without having to go to the solidification pit.

These liners/filter bags come in various micron pore sizes, so that if the solids are plugging up the filter and preventing drainage, you can get a filter bag with a bigger pore size, and if the bag you are using is letting too many fine solids through, you can get a tighter pore size.

I think they run from 100 micron nominal pore size to at least 300 micron nominal pore size.

I know a guy who makes and sells these liners at his shop. I think I will hit him up for some scrap pieces, since my wife can sew like nobody's business. I am thinking that the smart pots that I am using have two different pore sizes. The tight fabric for the sides, so that water does not pour out of the sides of the pot when hand watering it, and a larger pore size for the bottom of the pot, so that the pot will drain well and some roots are able to work their way through it.

This is what I am talking about, Willis.

I've sewn thousands of custom smart pots from rolls of non woven geotex. A roll of 8oz 15'x300' cost roughly $500 bucks, and can make several thousand dollars worth of containers!
