HYDRO DWC- Air Pump Requirements (LPM)

[astra910]

Hi people,
I need help in choosing the air pump for my 5 gallon diy buckets i'm planning to go with 6 or 7 buckets around 3,5/4 gallons water, so i'm in the middle now about the required bubbling how much LPM should i go with per bucket? i want the best grow possible not just to survive, and can i go with the bubbling through Veg and Bloom or i need little bubbling on veg?
Thanks for your effort in helping me GL.

Some of our members use large pumps with a manifold to supply multiple reservoirs. I use one 2 port 127 GPH air pump per tote with 2 large air stones. Also the pump runs wide open from seedling through to harvest.

I'm using this one in each of my tents and it is powerful. Each tent has 3 tubs with total 16 gallons of water with a big airstone in each. The water almost looks like its boiling there is so much air. I had 2 smaller ones but didn't feel like they were doing the job.

I do DWC in 5 gal buckets. I’m using the same pump that thesprinklerguy mentioned above for 4 buckets at a time and could easily do 6.

You will want to bubble your water through the entire grow.
