Nice set up all in all.
Here is a co-op set up me and a friend are doing for a couple of patients that can't afford the dispensaries:
This is an ebb & flow set up with a 600w HPS, 16 Chernobyls: half are CH4 meaning the 4th cut of cuts and the other half is CH5 meaning the 5th cut of cuts. Day 40 12:12, oh and it is a sog grow.
I just finished building my own personal ebb & flow, it is much smaller than the one on here. Living in an apartment in SF you have little room.

I am running 4 TGA plushberry's and 2 elephant stompers by Hazeman. They are under a 250w MH which I can up to 275w, 400w, or 425w due to the conversion ballast also I have a 190cfm inline fine connected to the filter which really helps keep the temps down. Since they are seedlings I only flood 15 minutes every five days and as they mature I will up the flood intervals. I am also running a small sog grow. Gudkarma might remember me from another thread when I had this weird system called a hydro heart which was an RDWC system (recirculating deep water culture) and it sucked to many moving parts, air pumps water pumps and was very messy I am glad I switched to ebb and flow. The first pic of the chernobyls is my buddy's and I help him and he teaches me a lot he has been growing for 12 years.
wish I has some questions or answers for you guys maybe in due time just thought I would throw some pics up and show what I am, and my buddy's co-op are using.
