I used 25 pound bags of dirt the first time I tried growing inside. That's one of my first mistakes and I've made dozens more.
It took quite a few crops over the course of a few years to hone down my skills and now I know my "Growing Your Own At Home System" will be exactly what you need to grow your own weed at home.
Feel free to ask me any questions you may have. Most posts have a comment section and I check them several times each day.
