Sitting here smoking some of the last run and smiling. Last run was the first, and expensive one. Decent chunk of $$ for a 4x4 setup. Just for personal use. Paid for itself and kept me supplied until this run was done. And I added a 2x2,lol. 1 gal's been drying for 4 days now, and 4 more gals are getting chopped in the morning. All for the cost of basically nutes, electric, and my time. Simply amazing return on investment compared to street/dispensary cost and quality. Who knew that you could smoke the best weed of your life for basically free? Seeds,soil,nutes,electric in total cost less than an oz. does. And in six months you've got a lot more than an ounce. Anybody that has been trying to decide if it's worth an investment I'd have to say hell yes. Keep it simple. Reap the rewards.
