Sounds like you should use Hydroton grow rocks for your system. I don't think it would over water them. You could let it run 24/7 or put it on a timer maybe like 15 mins on 15 off or something. Ask Zandor
Stormcooker Reviewed by Stormcooker on . Watering cycle...... I have a top feed drip system and i am not sure how often i should let it run. It shouldn't be called a drip system cause it shoots out more than just a drip. Is it possible to over water with hydro? Stupid question, I know. But is it? Rating: 5
