im thinking a lot of people grow for the same reasons...

i grow beacause its a very rewarding hobby, being good at growing any plant is a good thing for lots of reasons.i think its a positive and productive thing to do.

also i get lots of incredibly cheap weed, which has three benefits,
the first being that i dont have to mix with criminal types to buy any and all the problems associated with mixing with criminals.
i dont have to pay silly prices.
and i wont lie, i sell to close friends at good prices, which is good for them and good for me as it pays for production costs and helps take the sting out of any unexpected bills like car repairs or whatever.

everyones a winner! lol

and a theoretical benefit lol... if the worlds economy suddenly collapses ( not an outrageous theory what with all the wars and trade sanctions and the middle eastern oil wars that are going on ) theres riots in the supermarkets as supply chains dry up, how many average people could grow thier own food? thats a pretty valuable skill if the worst was to happen lol.
