Okay, I've seriously spent the past week doing nothing but research and feel pretty confident that I can take a stab at this. Done the soil thing in the past, ready to try this out.
I apologize in advance if this post is very scattered, but that might directly reflect on my current psychological state ;]

Decided to go with flow and drain style...
Here's where the questions begin.

Im doing six 5gallon buckets, individual flow to each with (im thinking) a 40 gallon rez

Question 1::is a 291gph water pump strong
enough this situation? 40gallon res, 30 gallons to pump to containers. too strong?

Question 2::GH 3 part, cal-mag+ and ph-down are the basic needs as far as nutrition? I know other growers will have different opinions, but I am not missing any important elements i hope. (going to be using rockwool and hydroton)

question 3::Purchasing PPM meter and PH meter both on ebay... I read that the cheaper style meters (basically the ones that aren't an arm an a leg) are inaccurate... Definitely would love input before I go ahead and make a purchase.. Here are links to both:
HANNA Primo TDS Meter, PPM Tester, Conductivity - (eBay item 280158176789 end time Oct-09-07 23:00:00 PDT)

HANNA HI98103 Pocket pH Tester/Meter/Checker 1/HI 98103 - (eBay item 280158208337 end time Oct-09-07 17:30:00 PDT)



So basically, If I'm understanding correctly, as far as assembly for the ebb and flow...
as long as theres water being pumped from a Res, to a tray (or individual buckets with a net basket inside), and it flows back into the res after your done... thats it. easy as that.

so i can just muck around with pvc tubes and rubbermaid containers and water pump until it works.. epoxy of course...

Would love some input.. Other things I need perhaps?
