Here are some pics of how we build our DIY smart pots.

We are constructing a 10 gallon smart pot

Tools to get the job done.



25 inch X 50 inch piece of geotextile fabric unfolded



fold in half into a 25 x 25 inch square



glue or stitch the two open sides. Here we use PL glue. this stuff is rock solid





smooth out the glue



really work out any bubbles and smooth that mofo out!



Repeat on the opposite side



You let the bag sit flat for 48 hours so the glue can dry/cure and expand. The glued edges will not break loose. PL premium is rank stuff.

This is what you end up with..



Now fold the bag inside out



make the corners touch each other inside the bag





All done!





So cheap to make and easy as can be

here is the data for the size of pots and cut size

no more fkin around, ran the numbers through a spreadsheet

size accounts for 3/4 inch of glued edge, and the gallons are at 85% of pot capacity

bag dimensions in inches

seam width: 0.75 / fill percentage (80-100%): 85

cut size: height x width / folded size: height x width / filled size: diameter x height / volume in gallons / volume in ml / volume in litres
4 x 8 / 4 x 4 / 2.1 x 2.2 / 0.03 gallons / 102 ml / 0.1 litres
