a plant from seed isnt any better than a clone in my opinion. bringing up a point about the leaves, stems and buds are bigger from seed this isnt true, while indoors a plant from seed will usually of been in veg for longer than a clone has been since it was rooted, which may affect leave and stem size but give them equal veg time and you shouldnt be able to tell any difference between a clone or a plant from seed.
there is nothing wrong with using seed besides the disadvantages mentioned above you may go through lots of seeds before you find a mother plant that you really like and even when you do find one you will probably always be starting more seeds looking for something better or might just want a little bit more variety and you may end up with several mother plants, but using clones has way to many advantages to ignore and will always be the preffered method by the majority of growers.
