Watts up DGC love being a member all the knowledge from you guys. I was wondering my tap water is 470 ppm. Do I subtract that from what I’m putting in nutrients say 1000 ppm? Or do I just keep the 470 and bring it up to 1000 ppm? 2nd question…. DGC cup I was wanting to plan on going do u know about expected cost? So I could start saving being married with kids and all, and living out of town traveling is the roads full of police around the 4/20/2017 dates.
Thanks yet to b a growers love
