Hydroton question

I have a 4 inch RW cube in a 5 gallon pot of hydroton. Will one dripper suffice. My pump cant handle n e more lines on the feeder so Im kind of stuck. My water is very oxygenated i have 2 air stones and my water recirculates which creates even more oxygen. Just wanna make sure I get decent coverage and fast root growth. Thx

One dripper fine you can move if you want periodically though once those roots are in the bucket you're good.
