Anyway, I'm caregiver for my girlfriend as well, and a friend of hers may possibly be giving me caregiver status as well. So, I'll have 6-9 plants flowering at once and I can build a space anywhere from 9 sq ft - 16 sq ft. I'm considering a 400w - 600w HPS and will probably get a 600 HPS to increase yield. I will be getting an air-cooled hood so heat shouldn't be an issue. I'll be growing in a soil mix and feeding with undetermined nutrients as of yet (hopefully organic). I won't be supplementing with CO2 or anything. This will be my first grow, although I've dabbled and vegged plants a few times and my girl has a greenthumb.

So, my question is, assuming that everything goes pretty well and I get decent results, how much yield of dried/cured buds could one expect using a 600w HPS on 6-9 plants in a 12 sq ft space? I KNOW that this is highly variable, but I'm just looking for an average assuming that everything goes OK and there's no problems.

Also, what would the ideal spacing be? I can build my area as large as I need it, so if I have 6 plants would I want 6 sq ft? 9 sq ft? What is ideal assuming your area is cool and well-ventilated.

Any feedback on this would be appreciated. Also, anyone in CO who has had a successful small-scale medical grow with clones from dispensaries I'd be interested in hearing about your grow experience/results and where the clones came from. Please feel free to share and post any CO small-scale medical grow-related stuff in this forum.
yes I've had a successful small-scale medical grow!!
Well I will start by saying this it is good to hear a rational person asking a question plus you are from Colorado same as me ha ha, I will tell you my experience and give you my opinion, I am also in Colorado, I am also MMJ recommended along with my wife, our first grow was with straight MH, it did okay but by my standards and lifelong experience not the product I wanted you know what I mean? So because this is a lifelong thing for us we invested in a very good system, the extra sun Hydrofarm HPS and MH combo switchable ballast, as far as I'm concerned after researching we got the best lamp available for veg to flower a eye hortilux mh blue 400 watt, you might disagree with that and I respect you if you do everybody has their own tastes? I can tell you with what I've got right now and in my opinion this is the best all-around spectral lamp for veg through flower and the spectral graph on the box proves it, anyway if I were to flower with six to nine plants I would say with our system and our type of lamp with 17 to 24% more of both mh and HPS in combination in one lamp I would roughly guess one to 2 pounds, but that's with my lamp? I'm not saying yours is any less or would yield less with what you're using even though in the back of my mind I have to think this lamp will yield more than usual standard stuff! So to answer your question about yield I would say that's probably what I would get right now at the present time even though I have not flowered with this lamp only vegged with it so far, from what I have read all over the Internet people are getting buds with the type of lamp I have during flower that pretty much is no different than outside, hopefully I wasn't too vague? Just thought I would give an opinion for you to the best of my guesstimate, oh and by the way three of mine are clones, and all the rest were germinated, this lamp brought up seedlings perfectly, so assuming temperature is no problem, size is no problem, and your buds come out pretty darned dense, I would say one to 2 pounds with six to nine plants, sincerely cherokee
