Plumbing help 8 4x4 tables

[icdog]

What is the best method for plumbing 8 4x4 tables in one room?
Likely be using a NFT method for the tables instead of F & D.
I would like to keep the res outside of the room to keep the water temps low.
Whats the best and least leak likely way to plumb this taking the water from a res outside the room into each table and then routing the water back to the res.

Thanks for any help.

First of all, I would use 4x8's versus 4x4's. theres wasted space using 4x4's with the edges, etc.

Depends on the setup, you can use 3/4" PVC running around the room. One for feed, one for return. Everywhere you need to connect to a table, use a "T" where the T is threaded and you insert a threaded barb. One end will screw into the T, the other end you can attach a hose, where you can plumb to the table. That will allow you move the table some. If you PVC directly to the table, you cant move the table

Or you can use hose for everything. HD sells a red hose thats $75 for 100'. compared to 100 for the black hose they sell at the hydro store. The red hose is far better, wont kink, strong etc.

Everything you need to plumb this is at home depot, except for the table fittings.

Will the tables be lower than the res? Because that creates a new problem which I have a solution for as well. LMK

I did 8 4X4's in F&D with 2 115g rezzies, check out my 8 kw grow below. I prefer 4X4 over 4X8 as there's less sag and they're easier to handle by yourself. Can't help you with NFT, that's about the only style I haven't tried.

Thanks guys.
dtfsux - Yes the tables will be lower then the res. I was thinking about this and not sure how to sort it out yet.
I haven't decided yet on 4x4 or 4x8 but I think the 4x4's will be easier to clean and move around.
Thanks for the advice, I wasn't aware of this hose at HD.
