another thing should i have something covering the rocks to block the roots from the light

I'm not sure on flood times but yes cover the rocks. I'm running a dwc style and noticed considerable growth when I blocked light from roots/water. Good luck!

Thanks for the reply from what I read 3 or 4 times a day on the flood by the time it floods and drains 20 min or so I guess should be good. What would be good to cover the rocks? I was thinking the smart pots would work If I cut some up but must be a cheaper way then that.
