I saw the idea for using glass bottles as watering globes for your plants! They drink as much as they want. Perfect if you are going out of town for a few days and they can be used for your indoor or outdoor plants.
It works best if the soil around your plant is already moist so water first. Fill up your glass bottle with water, then quickly stick the neck deep into the soil. Make sure that there is no immediate leakage or bubbles rising to the top. If there is, take out the bottle and try again until it works. I only needed to do it once. Neat huh!
