Hey all! So i've been a hydro guy for years now and have my hydro on lock. I am now helping a friend that just got their 215 card get started. There are a few area's where I have questions about soil mixes, watering schedule. As far soil brand goes I would like some help figuring out what brand to use/ what I will need to add ect... So far my thoughts are Roots soil (camo bag) or Promix soil. Do any of you use either of these, do add anything, how did it work? 2nd question: I feel dumb asking this but, from my understanding soil like Roots have NPK's already in the soil. So Do you feed with liquid nutrients, because I would like to! When do u start feeding with liquid nutrients. Do you feed nutrients every time you water? How often do you flush out your soil? I'd like Import from experienced soil growers who have good results! thanks a lot guys for the help in advanced!!
