Empty pop bottles make really good little greenhouses for starting your seeds indoors, too. Just cut the bottom from the top 3/4 portion and there you have it. I cut slits up the sides of the top. This is so you can press the top into the bottom for a snug fit.
I have started my second set of tomato seedlings in these. In this picture you can see the condensation formed on the top as the warmth of the sun heats it up. There is a tomato plant in there growing well, and when first put outdoors, it is protected from the harsh wind.
The plant can stay in this container until it is ready to be put in the ground. It is a really cheap way to get your seeds started, and is very functional.
Of course, I did not come up with the idea. It has been passed around on the internet. Great idea, whoever thought of it.
