  1. I just buy covers folks make from 3-d printers on Etsy. I’m wondering if brown cuts light enough?
    Maybe two layers?
    Also foil reflects well.

  2. I like your suggestion. Nice video! What are your thoughts about the best way to add nutrients to the system. after a week or two of operation. My system recommends adding nutrients after a week or so. But, they don’t give you a good method. Thanks’

  3. hi Chris, can we use a fish tank water filter (charcoal based) to keep impurities out of our reservoir? or would it filter out the nutrients and fertilizers too?

  4. Can you or anyone tell me what is the brownish slime on my roots and in my hydroponic reservoir, and what is the cause and what is the solution?
