When it comes to summer time and plants drying out, what I find works is taking water bottles (like Perrier water bottles found in the recycle box at work), filling them up with water, and then sticking them in soil about 2-3 inches in the soil. This lasts for about 4 days in containers.
For outdoor garden, I place it close to the plant and it last about 3 days. As the soil drys it allows for air to be released and allowing the water to fill up the spot where the air has been created. No need to worry about overwatering with this method, as gravity works its magic. No need to spend money on glass balls for watering. If you want to decorate them, modpoge them with tissue paper.

It is always so hot here in the summer and I like to have flowers and vegetables on my deck and in the yard, but can't afford the water bills to keep them watered between times of rain.
I live on a hobby farm and we've planted an orchard on our property. With the droughts that have been going on we didn't want to lose any trees.
Fill any empty recycled plastic bottle with water and upend it in a potted plant. This is a great way to keep your indoor plants hydrated during the summer or a vacation.
