Ok I was bored this morning and in the process of taking out the trash ! Had a couple of the two litre drink bottles and was hesitant to toss them ! Then got a bright idea to make a self watering seed starter since many times we just forget to do it ! I cut the top off at the ridge at the top of the label ! This was Mountain Dew,, diet of course,, but any would work as long as its smooth sided ! Then I cut the body down to about 4 or 5 inches ! So the center part was put in the trash. turned the top upside down and rested it in the bottom part just to see how it fit ! You want the mouth of the bottle to be about 1/4 to 1/2 inch above the bottom of the container ! Then I cut a bit of foil and put it over the top of the upper portion and slid the seal ring over to secure it ! That keeps the foil in place ! Used duct tape to make lift handles on the top part so I could remove the top from the bottom to add water ! Then poke a small hole in the foil for the water to get in ! Then add potting soil to top and add water to bottom ! Rest top in the bottom ! Should allow enough water to take care of new seedlings through the small hole in the mouth of the bottle which is at the bottom ! I know this sounds confusing but its really simple and one more plastic bottle is saved from the land fill !
