Topping usually triggers the hormones to speed up growth to make up for its loss. In return, most of the time, it also speeds up the flowering proccess. Males do grow the same as females after topping, no doubt about that but thats how you sex it. Then you must determine the sex of it. If you top it, and it turns out male, then you do what u must with it. If you top it and it turns out female then yur a happy camper.'

Of course not forcing it to do so is easier on the plant. Some people just dont like to wait as long. Plus Topping is a very good method because it increases yield and the plants upward growth is drastically slowed. Makes it very good for indoor growers.
