I agree with Weedhound. Anybody with a seed, soil, food, light can grow. Everything will work, just how well. Maybe not get anything at all but the plant lived 8 weeks...it worked. I think that after growing over 15,000 varieties of plants all over the damn world, battling insects that took me weeks to identify, grafting, consulting, orchards, grapes, hops, perienials, tree farms, etc...I have found out one very improtant thing. I am not an expert. The plant is. The cool thing is they tell you what they need, you just need to learn to read plant. I learn something new every day, and am humbled every day by nature and her gifts. I also try to pass my findings on to others who are interested or maybe don't want to make mistakes others have. BUT you come on this website and are looking for information on how to grow medicinal MJ. You are going to get advice on how to make the most out of the plant to capture the medicinal qualities of this fine herb. These folks have spent countless hours perfecting, to the best of their abilities with the resources available, their craft. They are not selfish and willing to share with you their experiences. If you want solid scientific evidence and facts then you should be reading botany and plant science. When you learn the basics you will be able to elaborate on that and tweak the plant for your needs. So in closing, you can grow an MJ plant anywhere between 40-105 degrees F. You will have some really different results and some will be forgetable. This site provides information about optimizing growing conditions to achieve top grade medicine. Grow as you like, but trust me this site is a gold mine of information with nice folks sharing their experiences with you for free, taking time from their lives to type it out for you. I thank you all for that.
Peace,
