I think you are forgetting the excitement and expectations that come from your first grow. There will always be someone who has never seen a mj plant grow. Now just think about it, they plant that seed and within months that tiny little seed has grown FEET, and within months will be taller than any plant they have probably ever grown. Of course they(ME) am curious, "How the hell Tall Is This Thing Gonna Get!???"
How many new growers really expect a 6ft+ tall plant within just a few months? Now I've never seen the process the whole way through but Hell even I could tell you if you showed me a picture of your plant what the approximate height could be, or at least could say what it won't be, just chill and help newbies out and a year later newbies will helping others.
