A heating pad would be a good idea. Just make sure to check the
watering as the soil will dry faster. A heating pad for germinating
seeds will keep the soil several degrees above ambient temps and help
keep the roots warm and help them grow.

When I grew cilantro it took 10 days to get the first sprout and 14 days to
get 2/3 germination. My temperature was about 72F, so at 68F your seeds
will take longer.
