Medical grow question...

[dejayou30]

I grew for 2 years before quitting, and I felt I had things decently dialed in on my grows, and I never got anywhere close to 1g/W. The closest I got was .21 g/W (7.5 oz) off one HUGE monster plant. I ran a 1KW in about 12 square feet in DWC setups, and my plants were always pretty healthy, but for some reason they never filled out like they should have to get those huge yields. I would recommend one or two huge plants to fill your space rather than a bunch of little ones, as its easier to maintain, but that's just me. :jointsmile:

Jorge Cervantes suggests you should harvest .5 g/W on average or you are wasting electricity and time. That means I should have been harvesting well over 1 LB per harvest but I never got anywhere close to that. I would not go into it expecting 1g/W or even .5g/W or you will be sorely disappointed. Not saying its not possible, but you gotta work at it for a while to get that kind of yield. My first two or three yields were barely over 2 ounces off 10 plants. Its much harder than it seems. Maybe its for the best that I quit so I can leave growing the pros and their .5g/W yields. :thumbsup:

Wow, that's a lot of light too. Was it in an enclosed space? Did you have good ventilation?

Well, I hope I can eventually do better than that, but I'm not expecting much the first go round (I'm still hoping though)...

Man, seriously. That sounds like a serious HEAT or AIR problem. If their is no Fresh air coming in, or the heat is above 90, yield's will suffer severely, i dont care what strain you have. I got all of my knowledge from Cervantez book and experience in the field, but i have read it Front to back a couple of times.


When i move to colorado, Preyn for 2010. Ill be renting a 2br apt. Legal # plants with 3kw's in a 4x8, and a sep. A/C unit. Hopn to get about 9oz off each of 6 plants. That's about .45 G/W which is BAD.

edit: W/D conn.-240v to 4-120v light controller for safety.

Always remember Volts x Amps= Watts, And you should'nt push it pass 50% load. so a 240 with 30amp breaker=7200W/ 50%= 3600 running watts. Ok i think i got off topic here.

Hey Illumination.. I don't think we can PM on here which sucks.

I'd heard C-99 is a good beginner strain, but I've heard it's also sativa-dominant. So, after talking with some more trusted sources I think I'd go with something like AK-47. Is Serious Seeds the genetics I'd be looking for in an AK?

go with the 9sf and if not too late go with a 1000w you will get much more light penetration. also look into scrog"s. you lay a screen over your garden when branches come through the screen you start manipulaing them along the screen by tying them down. everything below the screen is cut away. when you get half to three fourths full start flowering allowing for some stretch. the premise here is to create a screen full of top buds thereby increasing overall yield. fox farms is a very good product whether its soil or nutients. sunleaves guano is very very cost effective and can be added to your water just like liquid fertilizer. alaska is another low priced quality product. check out otooles nursery for best prices. if you get half gram per watt your doing really good. that really denpends on strain and getting your grow dialed in. each one will get better. use the above nutrients and you'll run little risk of burning you plants. good luck

meded so you can mededicate to mededitate

[MEDEDCANNABIS]

oh yeah and serious seeds for the original ak47 definately go with that

2 oz per plant seems really low? is that for real?

Anybody know of a reputable place to get clones? I'm looking for a place that uses known genetics like Greenhouse Seeds or Subcools or something like that. These places with 200+ clones kinda turn me off because there's a lot of crap and I don't want crap. I'm looking for some primo, well-known, proven genetics. Delta-9 looks like a good place, but I think they're way backed up on clones.

Your weight will depend on your genetics, vegging time, soil/nutrient mix, environment/temperature/relative humnidity, altitude (to some degree) and light levels.

All of the plants in this room were vegged for at least 6 weeks under 1000W Hortilux Blue MH's. They are flowering in a 12' W x 22' long greenhouse which is supplemented by 12 x 1000W HPS lamps. They started hairing up within 10 days of moving them to a 12/12 light cycle. The big sativas will likely yield well over a pound by harvest time. I doubt I'll get less than 3/4 lb out of any of them. Altitude of this grow is around 7000'. I could probably get a bit more size out of them if I was lower, but WTF? The product grown here is extremely potent and they're almost too big to manage as it is.

Best of luck with your grow. Be sure to pay attention to everything, all of the time. The devil is in the details. Keep a close eye on them and do whatever it takes to keep from stressing them.

Hi guys,

I'm considering a grow to cover my personal medicinal needs and wanted to get some advice before setting out. I would've posted this in the "grow" section but I've noticed that the responses in that forum aren't always that great for these types of "yield" questions.

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
