300watt 24 clone small scale rdwc: where to get my equip...links?

Question is: where are all the reasonably priced and effective water pumps, air pumps, digital ballasts and HPS bulbs?? Because I know that this community KNOWS whats up.

How many gph is usually good for a RDWC, and how many air stones should I use?
Should they be in the pvc at the top of the spiral? Or in the res? Or both?

Thanks!

good people. good prices. give em a call, they can help you out.

For starters, you need to decide how many gallons your system is. That will dictate GPH. Airstones? Some would say the more, the better. Heath Robinson would say you don't need one. Cold water holds more oxygen.

you dont have a store near you? someone should hook you up if you act like you wont purchase it anywhere else...

psh I use Amazon.

hydroponics.net has a good selection of diy hydro part. With lots being able to be bought in singles.
