Step 13: Summary
The soil really does seem to stay moist longer than it does in a conventional flowerpot with regular watering. My favorite part is that the plants will grow with very little help or attention from me.
The fact that all the parts used (the bottle, the newspaper, the compost, rainwater) are all recycled or free and can be recycled again is what I like a lot. The planter can be used several times and can simply be tossed into a plastic recycling bin when finished.
I've made dozens of these and what I like the best is that I can grow miniature crops of herbs and flowers for literally the cost of the seeds and with little effort on my part.
Thanks again to bbullet and his instructable which originally inspired me on the basic design.
Have fun and happy gardening!
