Hi, does anyone have testet (hell yes, i know) how mutch does it effect and what nutriens you have to give when you clean your water? example if you have house water witch have EC 0.3 and then you have clean water EC 0.0,
and if you get 100 grams weed with house water then you get… how mutch?

Your local water department should be able to provide you with a water report so that you know what is in that 0.3 EC. Here in the states our tap water usually holds some calcium and magnesium in it so I wouldn't be so fast to try and "clean" it. Find out what that 0.3 EC is as it may be better to use it straight out of the tap and reduce the amount of cal/mag you have to supplement.

How clean your water is doesn't dictate to more dry weight. More dry weight depends on genetics and grower skill.
