I am in the process of setting up my first UC run. *applause*
The set will be 28 site 13 gallon, 28" centers. I am planning on a shorter veg, (4 weeks) then flip, as the plants will be closer together.
I have done research and searched forums although I am not sure yet on how I am to place my res , top off res , chiller etc.
I have a 955L (252US Gal) res. that will be getting fed RO water on demand via float valve.
I am not sure how to setup/plumb the top off. res... Should I use the 955L as a holding for RO water, get a 100 gallon for the top off?
The system max I believe would be 28 x 13 gallons + epicenter + volume in pipes = about 400 gallons?
To my understanding I will want to run each site at about 9.75 gallons. So the entire system would be about 275 gallons.
I have a 1000L holding tank of RO water, but not sure if I use that as the top off, or I plumb it to another smaller res, via float valve.
I could use a 50 gallon barrel as a top off res and just fill that with RO water when it requires. Although, I am not sure how I would balance the nutrients back to where they should be.
You are going to want something around 300g Res.
I have a 6k room that is 15 site evo 13g setup. In that room they drink 40g a day.
You would be mixing nutes almost everyday with a 100g top off.
What I did with my RO holding tank was to T off the bottom one to a hose, and use gravity feed where you need RO, and for the top off tank, I plumbed PVC into it from a inline pump off the other side of the T on the RO tank so I could flip a switch and pump RO into my topoff tank, and I fill to whatever amount I wish to make up. Usually make 5 days worth or so.
A float valve on both reservoirs would create a self perpetuation top off of R.O. water form the holding tank.
float your R.O.
float your smaller holding tank.
float your epicenter.
Plants drink, epicenter gets water from smaller...lol 200-300gallons doesn't seem "small" tank, then the float in the smaller tank would bring water from the main 1000gallon holding tank and the float there would turn on your R.O. fillin g the system nicely.
^^ This is what I am going to do , as well as a shut off valve between the holding and top off res. My holding res is only 252 gallons (1000L), and I haven't gotten the top off res yet, although I have been looking at a 270gallon vertical tank.
Oh yes, I might be only running 24 sites instead of 28, so less volume of water.
I suppose I will have to have the top off res *not* get topped off automatically, as it would dilute the nutrient solution. When it gets low I would fill it up and re-mix nutrients
