Will my closed system require lots of topping up & nutrient management

Hello,

I am about to switch my HPA system online.

How much water will my plants hold? So how much will I have to top up? - With my dehumidifiers linked in in theory no water should ever leave the room

What is the best way to transition the nutrients between stages without changing the res?

Regards

Also, what is the best way to regulate Co2? as the room is air tight
 
Why has no-one replied to this thread? There must be people with experience out there in this matter. Any help is appreciated. I will post some pictures at the weekend as my setup is unique.
 
THis is what confused me.. you speak about how much water a plant can hold..when HPA is roots being in the air and nutes are sprayed on the roots..
There is no medium or rather the medium is the air.. so I can't answer the "how much water it can hold"
The nutrients is a general good one:
I would say look for the dosage from soil less grows in general coco/perlite , since plant don't feed from anywhere.
