My favourite method of doing this is to pop a few seeds into a few blocks of rockwool and mist it daily, either with a sprayer or with one of those special hose things. After the seedlings reach a suitable size for transplanting, then simply transplant them into your hydroponic system.

The seeds are started in cells that can be made of many types of materials. Some
are compressed peat and just break apart when the plants get big enough, others
are wells in foam, filled with a medium to support the seed til it gets growing. Out here we have lots of acres growing strawberries and peppers, they are all transplanted from cells. The plants are plucked out of the cells and mechanically planted behind a tractor.
