Im not an expert on watering systems (let alone growing in general)
But if this is your first/second grow. I would stay back from an automatic watering system, because of these babies not needing alot of water to grow.

You can run into problems like over-watering, mold, and worst of all since they are seedlings ive had them never sprout and turn dark brown/black basically dead.

18/6 is usually the best schedule from reading around but ive had great success from 24/0

Do you have a thermometer? If not it is important to get one especially with one that checks humidity.

On a thread on here it says that you want the temps around 78, also the humidity at around 40% for young babies and as low as possible for flowering to prevent mold.

Check out my setup i used bins like you did but i upgraded my Grow room alot, the oldest one had another bin on top with 12-26w CFL's on the top lid.
