Are there more than one UPM?
One with a fungicide added?

Maybe it was Pro Mix that has the fungicide in it?

I have the Fertilome and will start potting the cuttings I started on 01/13/2014 in one gallon containers.

Now I have to go to HD and buy the lights to grow them out.

Rafed loves this stuff, I haven't had good luck with it.

I do to but you have to be careful with water for the newly rooted cuttings. It holds more water that ProMix. I use it straight out
of the bag for one and gal up.

Yes I will be very careful with that. I lost many cuttings last year all because I gave them too much love.
