    make pH correction unnecessary

      There's an app for that, and a lens for the smart phone, I dont have one, there is a thread on it. Maybe someone that has one will jump in here, but you take a pic of it and it tells how much THC is there. I also would have no idea if it is accurate.


        That testing app is called Higrade.

        Here's a link to some additional discussion and sources.
        I grow using soil comprised of the compost I make combined with Foxfarm or other quality commercial soils as an amendment. Appropriate nutes as needed. State of the art LED lighting and an evolving system of environmental controls allows me to pamper my plants and let them tell me what they need.
        My goal is epicurean quality rather than high yield.
        I'm learning how to create cannabis tinctures and hashish and I almost always use a vaporizer to spare my aging lungs.
        Despite my avatar name I'm generally amenable and helpful. So, if there's a question I'm qualified to answer, hit me up!
