I find the size of the Utrasorb to be just about perfect for any size seed that I will be transplanting except beans which I prefer to plant in potting soil because it clings to their limited roots better.

Thanks.

I bought the Ultrasorb and filled up 75 paper pots and have at least 12lbs left. I'm going to use the dense planting method and should have plenty left for 300-400 starters before i bring in my much more expensive usual mix.
