i'm begining to start some of my seeds for this years garden and this year i got a starter mini greenhouse w/ qplugs, i'm used to using the jiffy pellets, so i'm not sure as to how much water to add to the plugs. i added about a 1/4 of a cup to each plug but they seem to be still kinda dry? does anyone use these and how much water do you add. thanks for any info, jim
