I have a new grow box arriving tomorrow and have a couple of questions. If I am not using all growing areas I would guess they need to be covered so no light gets into the reservoir. This is my first DWC system so any pointers will help. I choose this unit because it is compact and can be concealed easily as my space is limited and I have a 17 year old at home. Also what should my ppm's be during flowering? When I add water to the reservoir, should I top off with just ph'd water or with my nutrient mixture?
