In indoor grows, you should place around 9 to 16 plants per square meter using a SoG technique, creating a beautiful sea of green buds. If one of the plants grows taller than the others, you'll need to move it out to the corner of your grow area so it doesn’t shade the rest of your plants. They can grow up to a meter tall, but their average height is around 50cm tall.
