So I usually mix daily and just use but everyone suggested I go get another reservoir and mix a weeks worth well what's a weeks worth??? If your in coco or coco/peat approx how much water per pot per day? With 1 gal fabric I got it to down to where 10 would take 2gal per watering but mid flower I was mixing 4gal/day watering an hour or 2 after lights on and again an hour or 2 before lights off. Some input anybody??? Currently in veg just started week 4 but roots have been busting outsides since week 2 super fuzzy and white so they are healthy and hungry.
 
To be honest, I took a guess, then went a few sizes bigger. I just used totes from Homes Depot.

Someone who could give you a better answer....
@Bill284 or @Nunyabiz I think both have good experience with coco and might be right up there alley.

I haven't worked with coco yet, but its on the possible horizon with my new system.
 
A lot of factors for res size. How many plants is the big one and how big do they get.

Larger plants drink more water. Also heat is a factor. Hotter climate more water.

More water is good tho it helps grow larger bio-mass = bigger yields.

I'm organic soil and use a 70gal res and it gets filled up 1x a week.

I wood think this wood be a great question for your nutrient supplier.

Ask them how long the mix stays fresh before breaking down. Also you might have issues with growing other organisms in the res with nutrients so that could be an issue over time.

I hafta take my res outside 2x a year and scrub it and clean out the inline filter as well. All I put in my res is RO water.
