Great tip on starting with what you have! As someone who has ended up investing a few bucks into my grow, I still try to cut costs, and be resourceful by using what i have, especially when it comes to pots. One thing I would like to add is to stop the plant from growing tall, incorporate training techniques such as LST, and super cropping. With these you can train the plant to grow anyway you want.
