Note that in this video I specifically say that this is not how I normally do this.  In general practice I simply take any viable cores as they become available and add them to ebb and flow beds to regrow them.  To expedite this project and give some interest to the project I went out and picked up a bunch of stuff that works for this type of thing.

Also while three of these came out in three days it will likely be about a week before it is time to do another one, so enjoy these for now.  Again you can follow the entire playlist at http://bit.ly/indooraqua
