Undercurrent Question

I am trying to figure a way to put two seperate undercurrent systems in a 8' x 4' tent. The reason for putting two systems instead of one is this is going to be a perpetual grow and a group of three plants is going into flower every month so the nute strength will be different for each system. Here is the idea I had and was wondering if anyone had a better idea

Also there will be a 600 watter over each group of 4 buckets

Why not use all 4 buckets for 8 plants?

Looks like it should work fine other than that

Because 1 of the four buckets is a control bucket where you add nutrients and adjust the Ph

you can always temporarily move a plant to a second bucket while you add nutrients. As it is you're taking up space and wasting light in that area, at least in my opinion.

Soil? Nah...

Looks OK but don't see a chiller

I don't see how its going to work..or at least maintain a current. The pump pulls water from the line and then empties it into a control bucket. This increase in water height cause the flow to the other buckets.

It also appears that you have only one top off rez? I must be reading something wrong.

It can be done, I just built a 8 unit system for 3600 watts. It will just be more expensive as your going to need two pumps and two top off tanks, and unless you make your own chiller (which is pretty damn easy) then you will two of those as well.

If the top off tank is pure water, why does he need two of them?

That's how all undercurrent systems work

Because people use the top off tanks to stabilize their systems as it tops off. At least the smart growers do. UC can eat up nutes quickly, seems most are running around 50% strength of nutes in their top off tanks And that is why the best solution would be two tanks.

Yeah wouldn't hurt to run two but running one with plain water won't hurt the system with nutes as long as they get checked every day or two. Maybe a little slower growth. Though a second top off tank wouldn't add much cost and if you go half size wouldn't take up any more space
