Many people have this theory that you can put cannabis in a planter and it will just grow, you have to show it plenty of love and attention. You have to study your plants habits, likes and dislikes. Growing cannabis is not easy and does take some skill, don't get me wrong you can through it in a pot and under a light and water it and it will grow but don't you wanna get the best outta the plant as possible? There are alot of factors that you need to think about. Lighting, Food, Water, air quality and so on.
