Just a quick heads up man.. Don't ask that question. hahah, it's a hugee pet peeve for a lot of people. It's something you won't understand until you actually dip your feet in the water of growing. First things first, if all you are concerned about is weight, you really need to take a step back and take a look at why you even want to grow in the first place.
To answer your question:
The amount of bud you will get from your plants depends on 100+ variables. Temps, CO2, what sort of light you are using, what nutrients you're feeding them, what kind of soil you have, the amount of care you put in, how long you veg, etc. As you can see, there is no real clear definitive answer. Just grow man, it's an amazing learning experience. Appreciate whatever weight you end up with at the end, and start another grow armed with a little experience and SOO much more knowledge. You'll find ways to improve on your technique, and before you know it, you'll understand why people hate the question, "How much weight will I get?". Take some time and poke your nose around a few topics, do some research, and go into your grow with a plan.
Hah, I'm sure you'll figure it all out. Best of luck, man!
