So, I am somewhat new to the Ebb and Flow system. My question is as follows... How do I totally drain the reservoir when it is time to either clean the reservoir and/or mix and add new nutrient solution? It does not seem that I could simply lift the top table part because I may disturb the plants and/or knock them over. And the flip side of the question is.. How do I then add the new solution with minimal hassle and disturbance to the growing plants? I have found no answer or demo anywhere online. I would assume there is an easy way of doing all of the aforementioned tasks since ebb and flow is common and popular, but I have yet to figure it out.
