v1.1 instruction set to make a hydroponic planter from a 2L soda bottle.
These are actually crazy effective, the soil stays at a perfect moisture level and you only have to refill the reservoir once or twice a week.
Feedback on useability/readability/design very welcome.

@kris I did kind of a hack of this for some of my indoor planters a couple years ago and got great results.

Your idea is smart for, like, new plantings. Great illustration, too!

My take on this same concept was to get a yogurt container and poke holes in the bottom of it. Then I transplanted a really "rooted" house plant into it, taking care to ensure the roots could actually grow through the punched holes. You can even pull some roots through if they're well established.

Then put that yogurt container inside a non-plastic container with lots of water, pea-gravel, 1/4" minus lava rock, and some organic material.

Opaque glass or ceramic works well for the non-plastic container, but I would recommend using something that light can't penetrate, since most roots prefer darker non-light exposed.

The dark container slows evaporation, and the roots really like being able to find water in little cracks and spaces in the gravel.

@indie sounds like a really effective setup! I also have a couple yogurt cups sitting here, I was just going to use them 'as-is' but they could definitely make small hydroponics!

I will consider how to black out the walls -- since it's potting soil in the top and water in the bottom I can't do it with filler material alone. Seems against the point to use spray paint... A construction paper insert around the resovoir wall could work

@kris there's a lot of white space, so I'm thinking that it would be possible to get the text big enough to be a little more legible on preview. Thanks for making it though!

@rubah Font sizing, I hear you -- right now it's optimized for web, not print, but I am aiming for both in v2.0. Thanks for looking!

@kris where do you put the soil and plant?? This just shows where to put the water

@gattogateaux You put them in the top half of the bottle (once it's upside down!). I have used hydro planters before with great success but right now I don't have any planted -- once that happens I will definitely add photos with seedlings.

@gattogateaux You use soil (not all hydroponics do, though), I just don't have any photos with soil in.
