If the state you live in has a medical marijuana law, you can probably find a medical marijuana club that you can sell pot to. I have friends here in California that do it and make an extra $30k+ a year. I would do it as well but my wife is scared of what her parents would say. As far as you geek side, you could could build a high tech watering and environmental control system and put in a security / surveillance system to keep an eye on your growth. Just make sure you stick to the local limit of how many plants you can grow at once. A pound of weed sells for at least $3,500 and as much as $4,800!!!
