If you don't want to go through the process of activating the effective microorganisms, you can buy it already activated. Not only is it less expensive, but many of the microbes have recently been awakened from dormancy, so it is of equal or maybe even better quality for application purposes.
Please note: Update May 04, 2012 -- going, going, gone... This product is currently sold out. Sincere apologies for any inconvenience. The next batch will be ready later this month, probably around May 21st. Thank you for your patience as I am switching brewing methods to make smaller, more frequent, fresher batches. Happy gardening!
