I really like the Pro Hex seed trays. We bought ours back in late 2014 from Wally World. I also bought the Jiffy Seed starting mix. I'm going to mix it with a different brand of Pro Mix that I have left from 2014.
This past February, When potting up - I used MG Organic mix for the first two hundred or so plants. When I planted in solo cups for the fall garden - I had to use the MG regular mix - the one with the flavor berries in it...

What are you going to use to pot up in 2016?
