I have had good success starting from seeds of blushing susie variety. 7 seeds out of 10, could be more if I was more careful moving them out of their tray. Start seeds indoors in early spring as follows:
Start in tray, space about 1" apart.
Starter mix: 8 part coco coir + 1 part perlite. Mix should feel springy when slightly damp. Bottom watering just until you see the surface start to darken but you can't see the water.
Mine sprout as early as 4 days.
When you see the leaves, transfer to 2" cell. Use plastic dessert spoon to scoop out new sprout. Use same mix added with 0.5 part vermiculite + 1 part worm casting. Always water from the bottom. Expose to sunlight whenever there's any; otherwise, put under grow light for about 12 hours a day.
