I started with 1 room, i had a 4, 5 gallon RDWC set up i put togther. i had the pump and Air stones run 24 X 7...
I have since added a Veg. room and am running 5, 5 gallon buckets in there currently.. And I have a 4 inch round airstone in each bucket, and a Pair of Huge air pumps...
After adding the veg. rooom and the single buckets. I can tell you that i personally like the RDWC i built. Only 1 res. to check, Not 5... (what a pain in the Tush) lol..
