I'm an outlier, it appears. I start peppers and tomatoes and the like with the dense planting methods, using 50-cell trays into which recycled K-cups fit perfectly. That allows me to move sprouted varieties off the heat mat and into the light, while leaving un-germinated ones on the heat mat. It's space management. When the sprouted ones get big enough to handle they get transplanted into 2" soil blocks, where they stay (and grow quite well) until plant-out.
