it all depends on how much room you have, about 2 1/2 to 3 times is how much you can expect it to grow when you turn it over to flower. As far as yield or weight its really all relative yea you will produce a little less side buds if your plants smaller but your main coil is still a main coil and at the same time you let it veg out another month then flower well thats a month longer now you have to wait,
