How to decide air pump size?
I'm thinking of doing a 5 gallon x6 set up. Ideally, I'd like to run one air pump. How do you calculate pump size? Thanks.

I just bought the one on the shelf at the pet store and it works great with a circle air stone for the round bucket.

Some air stones are rated as ~ 4-8 lpm so just multiply the rating by how many air stones are needed (I have one in every 15ltr tub) and you will get the minimum lph rating of the air pump ie. 4 tubs x 5 lpm air stones = 20lpm pump. Remember to have an air stone in your res/brain too. Like Heisenberg said, more is definatly better so if you need about 20lpm go for 25-30.
Thanks for the replies guys. I'm still trying to figure out how to design this thing.
norcal im a nor cal transplant too lol, just go to one of the few hundred hydro shops we have here lol, if ur in my area i can give ya a heads up on where i go to. feel free to message me
its always something simple http://www.rollitup.org/dwc-bubblepo...l-size-b4.html
if you cant be good, at least be good at it

Thanks for the info peeps, question for ya if you are still around. Is the best design to have a large reservoir feeding into a control bucket and then the buckets the plants are in or can you just run the control bucket as the main reservoir? Im reaching the end of my budget so Im trying to figure out what is necessary and what isn't. Thanks guys.
All that is necessary is a bucket and an air stone/pump. They are each their own res, which allows for different feeding schedules, isolation in case of disease, ect. The way you are thinking (brain bucket) is more for ebb and flow set ups. It could be incorporated into a recirculating DWC set up IF that set up somehow suits your grow space, but I don't see any real advantage. Keep it simple especially if money is an issue.
What is your grow space and lighting situation? Looks like you want to run 6 5gal buckets. Is that one plant per bucket? How long do you plan to veg? All this makes a big difference when deciding how to grow.

I'm getting a 1000 watt set up, haven't built the room yet, but thinking around 6 by 8 to have room to move around the perimeter. Maybe 6 buckets is too many, I ll have to set up the buckets before I build the room.
I dont see how the "brain bucket" is anything like ebb and flow. Everything would be kept at a continuous level with a float valve and a main reservoir. Ebb and flow is flood and drain, water drains out for air to seep in. How is that anything like continuous aerated water?. The advantage to having a reservoir or brain bucket (recirculating) I can see right away is only having to deal with nutes once instead at 6 different grow sites. Dealing with one large res Ive grown before (10 years ago, NTFs, Ebb and flow as well as soil). DWC looks like something I could get into. I can veg for as long or as short as I want to. This is a medical grow for me. Budget isnt blown, while I dont want to spend on excess, a necessity is just that.
