generally speaking indicas are short.......you can cotrol the height of the plants by A:tie it down ,But a fan blowing it, C:topping it (i think)......if you tie it down, this will enable growth from the middle and lower parts......if you put a fan blowing on the plant, this will enable the plant to grow everywhere so as can stand up to the wind stream created by the fan.....if you top it (cutting the top), this will halt growth for a while and then the plant will grow two tops instead of one......the best way for me, that it has proven good is applying the first two ways.....tie it down and use the fan...as for topping i am not sure if it really helps for controlling the height though...it is surely useful to increase yield but the drawback is that not all strains are tolerant of topping!
