I've tried to call this hydro company but they aren't open yet. I wanted to know is 250ml of Example: Rhino Skin 250 ml per bottle. is this enough to ration for 9 plants in a full grow period?... Simple
5 to 10 ml per gallon (guess not sure the dose) depending on how many gallons per plant. 9 plants 1 gallon each 1 water is 45 to 90ml so 250devided by say 68ml per water or use = 4 waters That is how I do it good luck.. Hope that helps
