Just got back from town went to a hydroponic store and lowes. My dad and I are into hydroponics which is basically growing things without the sun and under a growlight and sometimes without soil and just water. It's pretty cool you should find more out about it. It provides a much more cheaper way to get vegies straight from a growhouse or wherever you a hydro system.
So betta wise.......I've been improving my setup a bit by the time it's done all my bettas will have 3.1 gallon I have calculated the expense to be atleast $70 and that's not including he gravel,plants decorations ect!!!!!
