OK mkb136 - got ya. I totally agree. I ONLY use seed staring media for ALL my seeds. Once they get big enough to pot up, I then use one of my potting soil mixes.
A little true story. When I was first starting with planting seeds, I did not know which end was up.
Ordered some packets from Parks, went out and dug up some garden soil and pain stakingly planted my seeds - sorted by size, tossed out the puny ones etc. Placed them on a screened breezeway. And waited. GERMINATION! Yay. And like 24 hours later, every freaking one fell over. And perished. I learned the hard way about Damping Off and had done EVERYTHING wrong - bad soil, slow drainage, too wet, too cool, etc.
