propagation tray with clear plastic dome
 

Ron,

Is a 10" / 20" propagation tray with clear plastic dome, good enough for seedlings and clones? Also, i noticed in the pics that the tray was divided by little pots of 4. What are those called and where do i get em?

Bedding plant inserts. A guess. They also come in a verity of shapes and sizes at any Home Improvement Store in the nursery department.
