Hey everyone. I just built my first airlift windowfarm using the V2 instructions on the our.windowfarms.org home page. There is a local hydroponics store in my town so I was able to get all of the stuff I needed from there. They pointed me towards some nutrient solution called Envy Part A and Envy Part B. I had initially planned to get all organic nutrients since I will be growing vegetables to eat, but it was just too expensive. Anyway, I’ve read some about “flushing” before harvesting the vegetables, and the guys at the hydroponics store offered some flushing solution, but I was wondering if just flushing with water for 7 days would work as well. I don’t know that much about flushing and hydroponics so any information would be nice. Thanks!
