water Cool way to grow in bottles of water

I have been growing super hot peppers on my window sill since the beginning of the year.  They are all in 1/2 gallon containers of water, with a little nutrient added.  Day 139 and I've got peppers on all of them.  Here is the how, and how to move them outdoors for the summer to bigger containers.  Monster peppers?  This is the way.
 
note:  video link shows my cucumber that was growing along with them, but I will be posting the pepper video very soon too.
