Height and Space
If you’re limited in height and space it’s no surprise that you’re going to want to pay special attention to how tall your plant is going to grow. There are very tall strains and other more short growing strains that are more convenient for closet or small-space growing.
This is more a preoccupation for people growing indoors that might have a very limited space. Some plants can grow up to 3m and are definitely not suitable for closet grow. However your growing techniques can also have a an impact on that. If you’re looking to grow in a Sea of Green (SOG) that’s can be a good way to grow tall sativas indoors. Sativas tend to be much taller plants than indicas however most strains today are hybrid and thus it’s hard to make such a generalization.
Whether it’s indoor or outdoor, if your grow needs to be discreet you definitely want to make sure you don’t get a plant that gets too tall. Seed shops and banks don’t necessarily indicate how tall specific strains are going to grow so if you’re especially concerned about height then it’s good to go for strains that are known to be short.
