Yield calculator: Ideas on mathematically formulating the most desired grow tool

So, recently I've played with the idea of inventing a yield calculator. A simplistic one with some basic parameters regarding strain, veg time, nutrients, grow style, and experience that may predict an approximate yield to within a relatively accurate degree. I'd like to use this thread to toss around some ideas on the subject, and eventually formulate a working formula to make this calculator. Please, jump in with any ideas on the subject :)

The first major stumbling block IMO in developing this type of tool is what to base it on. Should I use a limited number of reliable reports and develop a generic formula, or should it be a massive law of averages from wide groups of growers and a larger range of unsubstantiated data that uses tons of grow reports and yield numbers to make estimates?

While I dwell on this, I'm gonna try to narrow down the calculator to 10-15 fields that can be plugged in by users... I'm thinking a spreadsheet may be the most helpful in organizing this... Anyone here ever heard or seen something similar? I'm very intrigued by this idea, I feel like this could aide a lot of new/newer growers in their quest before investing in expensive equipment to fine tune their setup needs.

Personally i say it's a waste of time. I doubt any calculator could pull up a fugure more accurate and in a shorter timne frame than simply looking at your plant, and thinking right, 4 ounces.

Furthermore why would there be such a desire to know your yield in advance to take the effort to make a calculator. first time growers always get "ooooo what will i yield what will i yield??" as it's all just new, but after that you just tend to get stuck in with growing, and you kinda know by looking what is going on.

Yeah this is gonig to be way to mcuh work and it won't be as accurate as say the results fro ma lab or the actual breeder.

(growing exp, some function of time)(number of plants)(c)/(ammount of fuck ups)
C would have to be some universal grow constant*

Eh, its a great idea man.. I admire your enthusiasm.. But! I'm going to have to school you right quick.. about cannabis.

There is no way to do this.. though its a great idea.. but many experienced growers have already thought about this in the past, and they too.. found that its just not feasible. It will not work. "Why?" you might ask..? Well, its simple. It all boils down to each individual strain.. and that strains genetics. There are no two plants.. that are EXACTLY alike... they might LOOK like they're IDENTICAL.. but on the cellular level.. and genetic level.. they're actually completely different.

Plus, you have to figure that everyone's growing environment is completely different.. there's just too many alternating factors that play a part in final yields.. it just makes it too implausible to build/make a 'yield calculator' for those reasons.

Great idea though buddy! Keep the enthusiasm alive!

peace.

A yield calculator would only work for experienced growers, with specific setups/styles who already know what sort of yield they are capable of achieving, under a specific light, in a given sized area. But, then, the grower would already know what to expect, making the calculator useless.lol

IMO, go by the ol' "Gram per watt" pinnacle,(LEDs aside) divide it in two, and if you don't fuck up too bad, you might hit that number. :razz: Aside from that, it's a crapshoot, because there's just waaay too many variables to take into consideration, most importantly,..growing skills. Simply put, if you want more yield, put more budsites under your light, in the useable intensity zone. :)

There is a ton of great feedback here, and I'm going to go through some stuff more thoroughly and give the rep it deserves. I understand the basic drawbacks and concerns inherent with this idea, its complexity, accuracy, and its narrow range of appeal. I appreciate people here seeing it for the enthusiastic movement that it is, but I truly believe it can carry and hold some real substance. I'm still working on a presentation of my ideas, but I promise I will follow up something inspiring if not helpful. Thanks again for everyone's input here, lets keep it going :)

There are two valid (I feel them to be so) points to inspire others here as to why this is a beneficial and worthwhile cause. Many of today's medical patients need to ingest their medicine as opposed to smoke, and as such their requirements and needs are different than most as for the production and cultivation of their medicine. Also, there are always beginners and new growers, providing a tool (even if a primitive one) that shows hypothetical and likely results with certain methods would be a very effective and streamlined way to show people how to meet their bottom line.

I completely.fail to see how turning bud into edibles has any alternative growing requirement to growing to smoke, none at all. My first grow, someone said I would typically ne looking at around 2 oz per plant under a 400w, I averaged about that.

A statistical analysis of yeild per watt of HID would tell me how efficient my grow could/should be.

It wouldnt be a crystal ball by any means, but it could give you a balpark estimate of what you should be yielding.
And witch variables make the largest difference in yield.

The amount of data they curnched at YOR is incredible, its a good read....



"What has been discovered from the YOR database

In the final analysis, 53% of crop yield variations found in the YOR database can be uniquely explained with just four key influences every indoor cannabis garden has in common.
  • <LI class=listbullet>Lumens (31%) <LI class=listbullet>HPS Spectrum (14%) <LI class=listbullet>Experience (5%)
  • Hydroponic Medium (3%)
These findings put to rest two of the most debated questions among cannabis cultivators.
Which spectrum produces higher cannabis yields?
Does hydroponic media yield more than soil? ".



"Number of lumens uniquely explains about 31% of the variation in crop yield in the database."

I just watched 1492 last night. Everybody told Columbus, it can't be done, no use to do it, etc.... So more power to you, go at it with vengence. You may discover something new and great. And if you don't it will be a great experience. I am a farmer and I look through tons of data on corn yield, the same stuff applies there, hard to know all the varialbles, but tons of farmers make there desicions by this data. I would though be careful in getting to many varieties to start out. And I would make sure to go with a reputable seed supplier. DrGreenThumb would be a great place to start. Also Attitude seed, but make sure to stay with one breeder, to start out. BCBudDepot has some great genetics, I know somebody is going to nail me on this, but after alot of research I found them to be very trustworthy. This year I am growing, from BCBudDepot Sweet Tooth(fem), Sweet Dreams(fem), Northern Lights X Skunk1, from Attitutde Northern Lights x Skunk. All will be outdoor grows. Any thing I can help with let me know. Grow Happy and have fun....

this is a fantastic idea, and i hate to be the "downer" here, but i really think there are too many variables in growing to be able to produce a formula for yield. i look at the field (no pun intended) of growing and think that it has been around for quite some time, and if something like that formula hasn't been discoverd already (i mean, we are stoners and have some wild ideas) the odds of it happening now are pretty slim.

i do like to see your enthusiasm for growing though, put that effort into your plants and see what happens!

I think scientists or such could figure this out if they collected all the info they could from as many grows as possible on the internet and in contact with differen't breeder companies and famous growers. They could get pretty damned close, but with marijuana not even being medically legal in what 15 states no one has the connections, the manpower, the brains or the balls to figure this out *as they are either busy growing, doing other science, and fighting to get it legal

The need to ingest one's medicine will require a larger harvest weight than those smoking or vaporizing as per my understanding. There is also a different emphasis on the desired type of bud with those intending to ingest as opposed to smoke. I'm trying to get concrete numbers on edible crops vs smoking crops and the weights required. Thanks for you feedback!

Great points and great info. Thanks for the links, I'll add them to my list to scrutinize!
