Many similar ideas exist. I want to show you how to recycle 2l soda bottles and make a herb garden. The main idea here is that you water from the top and the excess water runs into the 'pot' below and so on. If you build one similar in size to mine you should be able to move it around or transport it easily. It also takes up very little space as it stands almost straight up.
Step 1: Hardware:
1)2l soda bottles.
2)Scrap wood, bamboo sticks, PVC or similar for frame.
3)Wood screws.
Step 2: Tools:
1)Knife to cut tops off.
2)Drill press / hand drill to drill holes through the bottle neck and to screw frame together.
3)Screwdriver.
4)Hand saw to cut scrap wood to size.
Step 3: Cut soda bottles.
Cut top of bottle off as shown.
Step 4: Drill soda bottles.
Drill bottle neck as shown.
Step 5: Build a frame.
Build a frame to hold your bottles as shown in the two sketches. Note that the opening of the lower bottle must be screwed to the top bottles' neck. I have not used any measurements because you can make your own custom size. I have made a 5 column X 3 row frame. This could be made to any configuration.
Step 6: Screw bottles on frame.
Screw bottles on frame.
Step 7: Stones, potting soil, planting and watering.
Put stones in the bottom of each neck for drainage. Fill with potting soil. Plant seeds or seedlings and water.
Good luck.
An idea for anyone not liking the raw look of the plastic bottles: hot glue some sheet moss to them. It will also help to prevent algaenation in the soil (that green growth in the soil due to light exposure).
Thanks so much for taking the time to share this!
My point is that ideally the surface treatment will not be porous.
The surface treatment is not porous.When you decoupage using paper or fabric it is sealed with a sealant like mod podge.Give it a couple of coats at least. If you are leaving it out in the sun, use outdoor podge. Use polyurethane after the podge coating if you want a stronger sealant .Please wait for it to dry completely between coats. It is now water proof .
As for how often I water - depends on the plant.When you feel it's drooping, leave the container in a bowl with water coming a little above the hole on the side. Water will seep in through the hole .
I did sent an instructable with pictures explaining the method but it doesn't seem to have gone thru. Will try once again.Meanwhile I hope this makes sense.Please read my comment given on April 3,2011.
Regarding decoupage, is polyurethane expensive to use as a coating? Would something like a soda can or other canned food can be cheaper or better in any way?
Actually the plants in this instructable are also going to be root bound, but such are the tradeoffs one makes using what containers are available and you can just use more containers for more crop yield. With some it won't matter as much, for example cilantro will bolt in only a couple weeks of warm(er) weather so you want to harvest it before that happens and changes the flavor of the leaves, meaning it doesn't get a chance to grow very large in warmer climates. It likes to grow deep roots though so ideally more of the length of the pots would be left on when cutting the bottles.
Forgot to mention that my next project is hanging pots with two litre bottles. Similar to the ones shown in the picture, but each bottle to be slipped into a bag with a draw string gathering the bottom part round the narrow mouth of the bottle and a handle on the wide top. Plan to hang them from my balcony rail. Shall try Strawberries this time !!!Thanks for the idea

I have also found that using the bottle caps instead of stones to stop the water from washing the soil out works really well too!
I live in a major city and have a tiny space for gardening so was looking for a good method of making a vertical garden.
I'm thinking I'm going to try and cut the bottom off the mismatched socks I have in my laundry room and stretch them over the bottles to shade the roots. Hopefully they won't be too tight and "squish" the bottles.
Nice instructable! Thanks for sharing!
