Air pump regarding bubbleponics

What size air pump will sufficiently run 16, 5 gallon bubbleponic dwc buckets?

I am interested in this too. Does more = better in this case? Because I'll march my ass right down to the pet store and grab an air pump for a 125G tank

I stepped up from using a 5 lpm pump to a 30 lpm pump in a single 5 gallon bucket and the rate of growth since switching has been enormous. So you need 480 lpm of air to really bubble those buckets up like the witches cauldron, although my way is probably overkill.
