I have been using the method described by Peter Thompson in his book Creative Propagation for about half of my indoor seed starting. He reccomends potting mmix covered by perlite for fine seeds and watering from the top to settle the seeds. Do not tamp the seeds in. He says that tamping the seeds in causes the soil to lose air and get packed down. I have tried it with some very fine seeds and it is working for me I am amazed to see those tiny , tiny seeds (portulaca for one) find there way to the potting soil. I settle mine in by using a spray all bottle .
