Resource Package

 This is a composite of Moon Doggie's analyses of the Indoor Yield-O-Rama (YOR).  As an offline resource package no connection to the internet is needed to use it.  The YOR database started collecting data about indoor cannabis gardens in 1996 with the twofold purpose of standardizing the way yields are reported among indoor growers, and to provide a basis upon which yields for a variety of garden configurations could be forecasted.  In the absence of any empirical cannabis studies or research being conducted by funded mainstream organizations found in industry, government, or universities the internet cannabis community has rallied to this effort by way of its contributions to this database.  These analyses were originally posted in five parts over a period of several months during 2001.  They included the first 160 records of the database for its source as depicted in the USENET threads (see below).

About Defaults used in Moon Doggie's Analyses
Defaults are certain YOR columns (fields) that can be said to contain info that is consistent from entry to entry. As a result the below four fields will not be examined in detail.

• GRAMS DRYWT - Only the indicator characters following the weight (c or d indicator, or blank) are at issue. The default is no indicator (blank). For all intents and purposes it can be assumed that dry weights border 25% of fresh weight.
• HVST - MANicured bud is the default harvested product being used and weighed. Consequently two records were removed from the original 160.
• hrs - The effect of different flowering photoperiods will not be examined due to the overwhelming use of 12 hour photperiods.
• variety - Since much of the body of data for variety lies in component entries, and since only root entries are being analyzed, variety will not be addressed at this particular time. The default variety is cannabis:-)

Note: Text contained within some of the graphs in the analyses may have its font slightly distorted.  In case you find that to be a problem, each graph has been hyperlinked so it will open in a separate window where it can be viewed without distortion.  Also, you will have to make use of your browser's "Back" button when viewing this resource since there are no links between pages once you leave this page.  The entire resource can be used offline.

Topic 1 - Lighting

Below are links to supplementary information on this topic brought about by a discussion in the alt.drugs.pot.cultivation USENET news group, home of the YOR and where the analysis was first made public.  A file named "Topic1 UNIX.txt" is included with this resource.  It is a condensed version of the threaded discussion to make for easier reading.  In order to condense the thread the following were done:
1-Any PGP formatting and sigs were removed because they aren't needed here.
2-Where there was lengthy and redundant quoted text, it was removed.
3-Posts not directly related to the topic were deleted.
4-References to the supplementary information (originally posted to usenet) is pointed out in the messages in which they originally appeared.  Instead of seeing references to the binary news groups in which they originally appeared you will be referred back to this page where you can click on the appropriate hyperlinks to view the information.

The file can be read with any text editor, however it is recommended it be imported into your news or mail reader.  It's in the UNIX file format, in many news or mail readers this will allow the imported file to appear in its original threaded form just as if it were being read in the news group.  Click here to open the Topic 1 USENET thread as text in your browser.

Here are the links to the supplementary information, they're in the order they appear in the thread:

Topic 2 - Substrate

As with the previous topic a UNIX file named "Topic2 UNIX.txt" is also included with this resource.  However, it is short and contains no supplemental graphs or html so it is not condensed.

Topic 3 - Plant-related factors 

Topic 4 - Misc influences on crop yield

A UNIX file named "Topic4 UNIX.txt" is also included with this resource.  However, it is     short and contains no supplemental graphs or html so it is not condensed.

Topic 5 - YOR regression analysis

This includes the predictive component of Moon Doggie's analysis, and concludes the series.

A MS Excel Yield Estimator application has been developed using the information presented here, as well as information from other sources, .  The latest version of the Yield Estimator is included with this resource in the Yields.zip archive.  Click here to view its readme file before continuing.

To use your zip utility to extract the files to an empty folder of your choice click the below link, choose Open from the download menu when it appears, then create a new folder from your zip utility where the program files can be extracted.  Or you can choose Save from the download menu then extract the files at a later time.
Copy the Yield Estimator

Note: You are not downloading from the internet but from your local hard drive where the Resource Package files and Yields.zip archive are located, this can be done without any active online connections.

Happy Growing,
