Question about adding water/nutrients to DWC
So I have got about everything ready for my DWC that I want to try one or two peppers, and some lettuce and such. I understand about getting the chlorine out of the water, getting the pH right etc.
However what I am curious about is this... I have two 10 gallon totes that I want to use. I have the flora nutrient 3 packs I purchased from amazon... Once I get everything going and the plants into the water and the nutrients set in... Obviously they are going to pull things out of it. Now when and how often should I change out the water, as well as add more nutrients, etc?
As the plants use water - do I just add more water as necessary until time to change it out? And only add nutrients when I change all of the water out?
I'm not looking for a big system and this is my first time, but I've tried searching for it and it seems I get rather long answers that beat around what I'm asking and make it more complex than it really should be. Any tips is greatly appreciated though!
