Professor Marijuana's 45 Day Grow Q & A

As promissed I have started this to consolidate questions from a few places where this topic has come up.



I'm more then happy to answer all the questions I can. I don't believe there are dumb question , if you're not 100% certain about something keep asking a different way until I understand what you're asking and can answer it in a way that makes it perfectly clear.

To summerise this technique, it is a style of growing that doesn't require a vegging period. Stable clones of the same strain are placed into 36 hours of darkness and go directly into a 12/12 light routine, or in my case 12:15 dark and 11:45 light. In my comercial facilities all our lights are put on a post that turns the entire lighting bank on and off together. In smaller grow setups where 2, 3, or 4 lights might be on individual timers I have seen where one timer gets bumped ar runs a little faster/slower then the rest and before you know it you only have eleven and a half hours of dark. Following my way allows for a bit of fudge room.

They remain in flower the entire time require to mature. In the case of a pure indica this can be as fast as 43 days from the start of 12/12 until harvest. The fastest strain for me was 43 days, this was also the highest yielding strain producing over 11 lbs of medical grade cannabis in approximately 36 sq ft under 2,000 WATTS HPS.

When I build a new room from scratch for a new grower it generaly cost just under 5k. This is taking into account my particular guidelines my clients follow when retaining me.

Here are some of my basic standards my clients agree to when I am building their room and teaching them. Of course you aren't a client and are free to do as you please, I'll just say there are reasons I do things the way I do.

I always buy the very best products available. I have come up what I believe to be the very best pieces of each and every item needed over the five years I have been perfecting this.

I never buy used equipment. Make sure you define your goals. I believe "Less is More," KISS, take the time to understand WHY you are doing something not just that it needs to be done. Keep detail records of what you have done and the measurements of from tests. I keep a form that I record daily readings of details I monitor. It's the details that seperate average growers from master growers. Give your girls "What they want, when they want it, in the amounts they want it in." Be patient.

The wisest words I have ever heard from a grower. Growers Two rules to live by.
Rule #1, Don't tell anyone
Rule #2, When you get out of jail see rule number 1.
J Cervantes

As sad as it is. Everyone (not you specificly) will steal you nugs. Family, friends, neighbors, utility people, police, students, even those you have spent years teaching and paid their way through college(yes personal) will all steal if given the opportunity. See rule number one. My point is simply be smart and remember locks keep honest people honest. Keep things locked up around others.

So, please ask away and as this gets longer check to see if your question has already been asked.

Good Luck

I am currently running 6 of the flo under a 400 watt mh. They have been flowering for 24 days now. Two days ago I ordered an hps conversion bulb so I could have propper spectrum. As I understand the flo already flowers quite fast. With that in mind my questions are few and simple.

1. Do you think using the mh in flowering for 25 day will have increase my # of days untill harvest? (Or maybe good?)

2. Will the conversion bulb be good at all or should I stick with the mh? As I understand conversion bulbs will give me a drop in lumens.

Either way things are still going swimmingly! Just always lookin for ways to improve

So, tell us about your technique. Your summary was extremely brief.

Question for you. How would you change your grow style if you were limited to just 3 plants in flower, and 3 in veg. The situation that most cardholders in CO are in.

Good stuff; first burrr. I am also from CO and I am on the registry as a patient and caregiver. My first card was 26 I believe. In 2004 I was raided by the DEA despight being on the registry. I chose to fight and became the first person in US history to have growing equipment returned by the federal government. Google "Dana K May, Fed back down in medical pot case" for news coverage. Also "dana k may, professor marijuana" will bring up a lot about the case. I then became certified as an litigation expert witness in marijuana cultivation and medical marijuana. If you read about Jason Lauve, who was tried in Boulder and rolled out of court in his wheel chair with 2 lbs of cannabis then you know one of my cases I worked on, completely vendicated. Also a Marine injured in desert storm was arrested with 71 plants. He was on the registry too. I was the only defense witness in his case and he had all charges dropped when the DA couldn't overcome my testimony. Most like yourself believe there is a six plant limit, 3 mature, 3 immature, WRONG. Read on, there is a loophole you can drive a truck through, it says 6 plants, 2 oz's OR whatever is medically neccessary!!!!! big OR.

Think about this, cannabis falls into the classification of a "LIGHT NIGHT PHOTO PERIODIC" plant. This means it needs to have 12 hours of dark to flower or become "Mature" out doors this is the Fall equinox, Sept 22, my B-day lol. How if you're growing outdoors can you have 3 mature, 3 immature plants? hmmm Can't be done, outdoors they are one or the other. The Marine (Arapahoe vs Kevin Dickes) that had 71 plants indoors was seemingly 65 plants over the limit. I showed that he would yield X amount over the time needed to grow and it fell withing what was "medically neccessary. So don't trip on the 6 plants, it's just a guideline.

Regardless, most growers indoors are yielding 3 oz's or so on a plant which is what I yield growing my way. I however, can get 8 harvest a year. Your 6 plants if you stuck to that could produce up to 18 oz's 8 times a year or 9lbs. Good numbers for that small a grow. Hell if you did half that, 4.5 lbs a year it would probably keep you well supplied, YES?

Peyote; one of my favorite ways of respecting the earth. Had a wonderful experience with the Hopie(sp?) Indians in the White Mountains of AZ long ago. 3 days in a Teepee that was the most enlightening experience of my life. My lady is 20 years my junior and has heard many times of that time. I would love to share that medicine on the high deserts some day. Unfortunately it doesn't seem to be as abundant these days. I hope to share the experience with her some day. I digress, the MH will not effect the flowering time. If at all possible I would try and add the HPS instead of switching places. The buds in my avatar were grown under a combonation of MH and HPS from start to finnish. I am a big believer in light, can't have to much. If you must chose one or the other, of course HPS for flower. But I would take a greater amount of MH then less HPS if push came to shove. Light is getting cheaper, try to invest in more light if you can swing it. As far as conversions, anytime you cut corners to save money there is a trade off. If I were starting from scratch I would by as large an HPS as I could and go from there. You can veg or flower with either. One nice thing about my technique is I don't require a vegging room. I buy all HPS digital ballast with adjustable power settings.

Hey Burrr, that's a big task to go through in detail. Not sure how to go about that without a step by step, detailed discription which would require much time. I suspect that's what I'll end up doing but will require several installments.

It requires a bit of experience and I'm assuming this is not the strong suit considering the forum title lol. I'll say that I grow hydro, without vegging, from clones. I use specific equipment, under HPS, with the nutes I prefer, etc etc. I guess I need to figure out what is a good size setup to use as an example

Cool thanks for the tips. At the moment I'm confined to a closet and any more than 400 watts is too hot. And I am indeed upgrading to a digital ballast as doon as I harvest and no longer need to spend money at the dispens. And holy crap those nugs in your avatar are bigger than footballs!! Much props! Once I figure out how to get the pics off my phone and onto here I would like to share.

As for the peyote I am still yet a young pup, and unfortunatley am aware of the near extinction the cactus has come to. Although if you want a similar experience, you can order san pedro cactus powder online and make a gross tea that's great!

The nugs in the bowl grew in a 4x4 closet with 2,000 watts. So I am concerned that a 400 W is to hot for you. It begs some other questions. First what size is the space plus hieght please. Is your ballast in the closet? An old coil ballast can add 10 degrees to your room. Is the light cooled? I'm concerned that there isn't enough circulation which will kill your yield. Also what is the distance from light to plant? Indoor growers always complain about yield but most of yield issues are tied to method of growing and enviroment. If you get your enviroment right you'll get much bigger yields. In little areas you need to have enough space in your containers, adequate C02, and LIGHT management. Never to much light. If you are not familiar with the way light works here's a quick lesson. The closer your light the better, mine are generaly within 3 inches of the plants and adjusted daily. You lose light really fast if you don't stay on top of it. At a foot away from the plant a 1000 w light becomes 500w, at two feet it drops to 250 w. Each foot cuts the lumens in half so a few inches will impact things a lot. Just maintain good light disapline will pay off more then any additive you can dump in. Give me info on the closet and I'll give my 2 cents if you'd like. Your next grow lets talk about containers, medium, and lights. I'll bet we can triple your yield. As far as cost for new lights. Ponder this, $400 for 1000w digital ballast, $150 for hood, $120 for bulb is less then $700. If you increased your yield 2 ounces would it pay for itself? Food for thought

hey prof i have a question for you

I have 8 fat ladies under a 600w in a 4x4 tent. they are in 3gal pots. I have to keep my light further(around 18'' some more) from the plants in order to light them all. They dont even take up the whole tent, the reflector just doesnt seem to spread it enough (its a radiant).

I have temps pretty much under control mostly in the high 70's max temp was 84 on a hot day. I can bring the AC hood within inches of the plants with no heat issues but can't because the outer plants wont get enough light.

Would a 1000w solve my lighting issues? would the increase in yield be worth it the extra $350+ it would cost?

I can put up some pics if you need a better idea what im lookin at

Thanks

How refreshing to find another grower that really knows his stuff!! I'm pulling up a chair Professor.

Whoa sweet jeasus! 11 lbs in 43 days from a 6ft by 6ft room with only 2000 Watts? Do I have that right? That's 2.46 g/w...amazing! Heath Robinson is the only other guy I've seen with results like that! I hope you don't mind if I ask some questions because I always love to learn from the masters. Here are my initial queries:

1. What strain gave you such phenomenal results and if it's not one that's available from a seed bank,(i.e. clone only) could you perhaps throw out a few recommendations that have worked well for you?

2. How many plants did it take to get you 11 lbs?

3. What style did you grow them in? For instance, SOG (lollipop - just main colas, no side branches), SCROG, LST, supercrop etc.?

4. Why the extra 15 minutes of darkness instead of just straight 12/12?

5. Do you use CO2? If so, how much would you estimate it boosted your yield?

6. Insofar as nutrients, I'm currently using GH flora series, what do you think about GH and are there any other additives you like or different nutrient lines you recommend? (I often think much of the stuff out there is kind of a gimmick. GH also works well in aero because its very clean which is what I require)

I'm sure I will want to ask you more stuff but I don't want to pepper you with too many questions at once.... Well I do, but I wont

43 days total, no veg time? thats crazy talk lol

if im not mistaken i believe he has grow movies or videos out.correct me someone if im wrong

Here's the link to the article in which the Prof refers: http://www.norml.org/index.cfm?Group_ID=6222&wtm_format=print

I currently run the 4x4 square tubes (ala stinkbud) with the ez clone sprayers inside, using 2" net cups and foam plugs, no medium of any sort. under 2 1000's on a mover. My question is do you think that dwc would produce heavier plants than the tube set up? I don't veg except for the time they spend in the aero cloner, which is until they have a good 10" of root growth usually about 2 to 3 weeks from cut day. with dwc I wouldn't be able to have as many plant sites, but would the greater area for root mass make up for the less plants in increased production? or with me not vegging would there really be minimal difference?

My purple erkle finishes in 40-43 days. I veg for a wopping 7 days.. 4k lights + co2, hydro, SOG. I pull 8-10lbs. You getting 11 lbs off 2k, soil, errr looks like soil. What are you doing different. What strain are you working with? The name of the pic is 60. Wouldn't be day 60 would it?

...your op sounds more realistic...I would love to see your work! Got a journal?
...(IMO)2+ lbs. per 1K is the most yield heard of (someone correct me if I'm wrong)
....I thought I was doin' big things pulling 1lb each 600 (hydro, SOG, cO2).

i have seen five pound plants off of one light. but you you gotta grow trees with aero or dwc etc. this aint no ebb and flow or drip system with cubes were talking here.

i have some questions for the proffesor myself and i posted something similar in another thread but it went unanswered. i will try it here because i, like you, am very skeptical of his claims.

you say you can pull 11lbs out of 36 sq ft? im looking at your plants here and they are very nice but they certainly are not 1lb plants or half pound plants. they look like a solid qp plant. and it looks as if each plant is about 2 ft apart, is that a fair guess? im just doing some quick figures here and by my count you are getting about 6 oz maximum from 4 sq ft from looking at the picture. that comes out to roughly 54 oz per 36 sq ft which is almost 3.5 lbs. but you are claiming triple that yeild. so you are telling me that you are getting 18 oz per 2x2 area? im sorry bro i just dont see it.

i have some other questions too...

most strains take at least 8 weeks to fully flower and some upto 12 weeks. what kind of seeds do you use to accomplish this result? only auto flowers can ripen that quicky(like lowryder) and thats all genetics and they only get upto 45 grms a plant. those also require another 15-20 day seedling stage to obtain those results. correct me if im wrong, but what im reading is that you can take any pure indica strain and flower it in 45 days? it can take upto 2 weeks for a plant to even show flowers.


here is a strain that is engineered to flower in 45 days

AVERAGE FLOWERING TIME

Indoors: 40-45 days (after a 15-20 day seedling stage)
Outdoors: Ripens approximately 60 days after seed is sown.
Note: 100% of plants display the auto-flowering genotype.

AVERAGE HEIGHT

Average Lowryder height is 12 inches. Minimum: 5 inches. Maximum 16 inches. Lowryder height is very light-dependent, with slight phenotype variations.

LOWRYDER YIELD

Depending on light and other factors, Lowryder yields up to 45 grams.


id like to know how you are in 45 days, getting double what they are from an indica strain that isnt even an auto flower?

im not trying to start trouble, i just really want to know how you are accomplishing these yields?

i look forward to your response, thank you.

I doubt the prof has run off. I do wish he would journal one of these grows though. I'm still not calling bs. It might just be possible with the SOG style, fast big strains, co2 and everything dialed. I read somewhere that he likes c4 as a strain w/ big yield.

Professor, you know your just baiting the trolling rod when you brag about monster yields without detailed pics.
