use a pipette or a plastic syringe for early seedling watering. works a treat
I germ seeds in a paper towel inside a plastic ziplock bag, once the seed pops open and you see white I plant it straight into its final container and use a couple of mls of water in the syringe.
Finally I put a clear plastic cup over the seed area to keep heat and moisture in till its grown big enough to remove it. Just keep adding water every other day till it gets big enough then you can up your waterings and nutes as usual.
I highly recommend to use the final pot from the start to reduce stress, and keep the light at least 3 or 4 feet high to begin with to maximise the plants stretch, once it has stopped stretching you can lower the light.
