Why is growing large cannabis plants indoors so hard for some people? The reason is people make it hard on themselves because of the complexity of others opinions. The More complex a person is the more negligent to others they are when they talk about growing cannabis. Its all a bunch of bullshit when people start getting away from the basic 17 essential nutrients a plant needs. As long as the nutrient sequence stays available the plant takes what it needs and anything else is bullshit. Some of you got it but some may not have gotten it yet.
