This product took over 4 weeks to arrive and is not what is advertised. First the tray is about half the size as the one in the picture on Amazon. Second, the seeds were not the ones advertised. It seems that the supplier had old seed stock that they needed to move as only about 10% of the seeds they did include are sprouting. This was really a disappointment, especially considering the price. I knew I was overpaying for the item when I ordered it, but figured I was paying for the convenience... lesson learned. I wouldn't repeat a purchase from this seller.
