how much water per plant in this system?

I have a purpose hydroponics tub but for the next run I intend adding and adapting a container and adding to the system so instead of 2 I'll have 3...so how much water will I need to circulate for 3blueberry ? thanks in advance. ....

Your going to need to post a little bit more info to get a good response.

What kind of system are you using(dtw, ebb and flow)? What medium? How big are the containers? What size is your resevior? Are you asking how big of a resevior you need or how much/how often you should water them?

Give a little bit more info and someone should be able to give you an idea.

sorry hydrponics NFT. http://www.ebay.co.uk/itm/Nutriculture-GT424-Gro-tank-complete-NFT-Hydroponics-Growing-Plant-Kit-System-/140909074968?_trksid=p2054897.l5658.......45litres and 40 litre tub so allin 95 liiters capacity but obviously I want st keep nut costs down so how much nut water should ihave in the system ..

if you want to keep nute costs down, you should run a recirculating hydro system instead of drain to waste. you will get a whole lot more out of your nutrients. you could keep recirculating for up to 10 days with air stones in the res.
