Ok tex I'll Bite,

Your running a drip system

What Are you growing? (as if we didnt know) but What? seedling, clone?

You say your Free Flowing on the roots how much air is getting to them?

Its My understanding that the roots need air as much as they need water?

off hand I would recommend a Cycle timer and dependent of how old your ladies are the young get a short cycle like on for 5 min off for 20. so every 25 min you will hear the pump turn on for for 5 min and then be off for 20 allowing the roots to breath, the older get A longer cycle.

But Dont take my word for it I am new to growing in general, but I have been lurking and reading for months trying to get a better understanding so when i start i hope to have 0 Problems. Hope fully one who has more experience in this can give you the best advice.
