Sure, pot will soon be legal, but don't count on being able to buy it any time soon

"Everyone knows clones are the only way to propagate MJ successfully"
-Patently false.
Growing from seed is just as good, offers you breeding options, and genetic diversity, which can save a home grower from total crop devastation. The only downside is that it takes longer.

"If you grow the pot and bring it to me, I'll dry/cure it and charge you for my services. Of course, once it's legal to sell pot, then I can add that to the business."
-Terrible idea. The drying and curing of pot is probably the EASIEST step in the process, once the plant is grown and harvested. Bringing your freshly cut plants to someone else to dry and cure sounds like a great way to lose some of your crop to some asshole that just got you to do all his work for him, who hands you back a portion of what you handed over and blames the loss on mold, insects, or the fact that the stuff loses weight when dried, then he sells or uses your crop.

Facing facts here: The people who know how to do this stuff, and really do it well, are criminals, and have been for a long time. That is not to say that there are not honorable people out there who would get into these lines of business, but this has been underground for a very long time, and technically still is. If you have a friend who knows what they are doing and can help you, great. Hiring someone you don't know to do any of this is just soundly bad advice. Everyone needs to remember that pot is still FEDERALLY illegal, on par with heroin, and the DEA can come bust you whenever they want. New AG Rudy Gulliani or Chris Christie will make sure of it. A MEMO from Obama to his AG is all that is standing between pot businessmen and jail right now. A MEMO.
To that point even in Obama's America I had a friend a few years back that DID have the DEA pay him a visit in Medford to repo all his growing lights, supplies, and about 12 plants. This was a strict home grow, not-for-profit scenario. Not large scale, not hundreds of plants, he was actually doing a pretty poor job at it. ALL IT TAKES IS A CALL FROM YOUR NEIGHBORS.

The first step in having a successful grow is to analyze the situation: Where you live, how close to your neighbors is the house, how your neighbors feel about the subject, how close to a school you live, are there kids next door, etc etc.
Growing pot SMELLS. Even one plant. Mitigating the smell while keeping adequate ventilation for steady CO2 supply is the largest hurdle involved. (Unless you wanna spend the $ on a fancy CO2 system) The plants themselves need little more than a bucket of soil, water, and a light set on a timer. They are hard to kill using soil. Hydroponic setups are nifty but for inexperienced growers you can kill a whole crop in a day with one ill timed nutrient blast. Fertilize in the morning and come home from work to dead plants. Soil mitigates the transmission of nutrients and one can see problems starting and flush the pots to bring the plants back. It stunts them and may cause hermaphrodites to show, but it won't kill your crop in a day.

In conclusion, I could pick apart a few other comments here, such as "Buy pot from me" guy up there, but its a waste of my time. I will say this: Loose lips sink ships. If you wanna grow your own pot, do the research, buy the Jorge Cervantes grow bible, buy your supplies discreetly, and set up your grow area somewhere private that will not be stumbled upon by neighbors and or snoopy repairmen coming to fix your boiler. Do everything yourself, tell few people, if any. Until something is done federally your day could be ruined REAL FAST doing this, especially under GOP rule. Charlie Baker is not gonna come save you either.
I say all this as someone who has successfully grown my own stash here in the Boston area, indoors and outdoors, and who has been busted by police for a pot related offence IN AMSTERDAM (Where it's "legal"). The moral of my story is people should not get too comfortable with any of this, we are still talking about a controlled substance. The local yokel cops aren't gonna come after you but they're not gonna warn you when the DEA trucks roll through town either.
