In my first, not so successful, attempt I did use about 50/50 (volume) sand
and peat. Since my pots were outside I was worried about the seedlings
drying out.
Joe points out that his very light medium makes it very easy to transplant
good size seedlings without harming the roots.
Robert, what was the environment you had success with?
Indoors? Outdoors? What were the temperature and humidity excursions?
How much sun?
