Cannabis is a canvas. Don't be afraid to make mistakes.. you might just grow ;) All plants on my page are autoflowers, and none of them would be as they are, if un-trained... Plan for the best scenario.. a healthy plant is barely affected by stress. For a first time grow, I recommend to not train, so that you can see the progression of improvement gained by learning to train your plant for more main-colas. Feel free to ask me anything. Happy growing!
