If you mix some kelp into the water that is drawn up by bottom watering,
the plants still get the benefit of it.
edit:
Note that you do not need to do that every time that you
water the seedlings, 2 week intervals would be plenty.
The seedlings will still grow if kept moist even without that.
It is only an enhancement to emphasize root growth after
potting up from seed-starting cells.
