Nice setup! Do you have any pictures from inside the shade clothes? How did you construct it? Oh interested about the bags as well haha Sorry for the big bunch of questions
About the nutrient
temp: is it also placed under the shade clothes? Maybe dig it in as some other user in this forum has done. A chiller can be used but that seems a bit expensive to me. Anyway I have to deal with the same trouble soon as well. Will make an update by that time (2 or 3 months from now).
