One thing fo' shore: Cup Numbas 4 and 7 don't never get full. They's blocked. That leaves Numba 9 as the winnah (unless the stuff solidifies, and the thing getting poured into counts as a cup). #5 is out forever and ever amen becuz there aint enuf source stuff to fill it. [/Game Theory]

Lost my wedding ring scuba diving a half-century ago. Hey... If you looks close at my left elbow, you can see the scar that starts just under my yellow shirt and runs down and around my elbow. That arm does not straighten out all the way.
Jeez -- a pic once on the net, is forever on the net. But at least you can clearly see the fangs... But I knew a guy that would catch two-step bamboo vipers just with his hands.
When I warned him he was gonna get bitten by the ugly green snake, he said, "It wouldn't dare."
He would hold one by the head and 3/4 of the way down the body. Then he'd drop the head and wrist-snap the snake like Indiana Jones. It would pop the head off -- and he could hit a target with the head. He could also whip-snap and hit a cherry with the snake head. When the cherry du jour saw what hit him, he would scream or even wet himself. Or both. I loved that guy.

@Boo -- MySonTheDoctor sez: HEAT it up, then COOL it down.
The reason for this sequence: When you put a heating pad onnit, you increase the blood circulation specifically in the injured area . This removes owies in your muscles/bloodstream.
Then you cool it down to calm down the local upset nervous system.
You are only doin' half, my very good friend. Half is good, but both is more than 2X better.

HEY! Sumbody put "World Record Holder" under my posts!
Ever kewl. I am very possibly the longest in situ Internet denizen with the same handle forever and ever, amen.
Always been Unca Walt, never anything else. And been that way since the 90's. A third of a century, and never any other handle. World Record, I think, considering the size of the "Internet" population back then, and how many would be left today of just the early Netters -- and all the handle changes.

OK... WTF is it? Green and tan and umber... Clearly it has to be weedstuff. Kief? But I never knew kief was multicolored. Thought it was dark brown.

Erratum Document for Previously Approved E-Thesis Submission
A post-approval (re)-examination of the raw data discovered unrecoverable errors in the
handling and reporting of the water potential data, with further issues regarding the nature of
the treatment differences. The general errors are:
1) Upon further review of the raw data logs it was discovered that the Control and Mild
Stress treatments were in fact the same (ref. page 38). Both treatments had the same
number of irrigation events (i.e. total water applied was the same) in all three trials.
The irrigation events were offset by 1-day but they both occurred at 2-day intervals.
a. Resolution – Any observed differences between the control and mild stress
treatment should be disregarded. Detected differences in agronomic and
metabolite production between the Control and Mild Stress treatments can only
be attributed to random chance and variation in the growth facility, not a
response to distinct irrigation regimes. Affected Figures – Disregard Control and
Mild Stress treatment effects in Figures 4.11 (page 54) and 4.13 (page 55)
2) Raw data was not properly filtered to remove erroneous readings (e.g., positive values
of plant water potential; non-sinusoidal or flat line response) resulting from instrument
fouling and condensation within the sensing chamber. The inclusion of erroneous data
resulted in skewed relationships between cumulative plant water potential and
cumulative vapour pressure deficit.
a. Resolution – Disregard the relationships depicted in Figures 4.1 (page 44), 4.2
(page 45), 4.3 (page 46), 4.4 (page 47), 4.5 (page 48), 4.6 (page 49), 4.7 (page
50), 4.8 (page 51), and 4.9 (page 52).
3) The apparent two-phase relationship between CWP and CVP shown in Figure 4.1 (page
44) and subsequently highlighted and independently analysed in Figures 4.2 (page 45)
and 4.3 (page 46), is the result of missing data (logger failure) during the middle phase
of the first growth cycle; the missing data was not properly accommodated resulting in
an apparent separation of the response relationship between early and late growth
periods. The subsequent analysis of flower cycles 2 and 3 included an analysis of this
artifact-based separation; as such, Figures 4.5 (page 48), 4.6 (page 49), 4.8 (page 51),
and 4.9 (page 52) are not meaningful as there is no data to suggest or support treating
the data as two distinct groups.
Based on the above errors, any conclusions outlined in section 6.1 (page 62-65) should also be
disregarded.

ABSTRACT
Irrigation Management Strategies for Medical Cannabis in Controlled Environments
Jonathan Stemeroff Advisor:
University of Guelph, 2017 Professor M.A. Dixon
Medical cannabis production is a new industry in Canada and represents a challenge
for the production of a repeatable and standardized product for medical use. A reliable and
reproducible environmental control strategy can contribute significantly to meeting this
challenge. Irrigation management and control of plant water status is one of the key
environmental control elements. To assess the effects of various irrigation management
strategies this study deployed in situ stem psychrometers to measure the water status of
plants. As a routine feedback device for irrigation control these devices are not ideal for
large-scale production so correlation with the key environment variable representing the
aerial demand for moisture (vapour pressure deficit) was assessed. By establishing a
relationship between cumulative water potential (cWP) and cumulative vapour pressure
deficit (cVPD) an irrigation management strategy that predicted plant water status based on
measurements of cVPD could be employed. Three treatments; control (irrigation events every
1-2 days), mild-stress (irrigation events every 2 days), and moderate-stress (irrigation events
every 3 days) were tested. The effects of flushing were also investigated to determine
whether it had the intended effect of reducing nutrient concentrations within the dried bud.
Through the use of psychrometers, water status (cWP) thresholds were correlated with
humidity (cVPD) thresholds and reduced irrigation frequency resulting in water use
reductions up to 45.7% which had negligible impacts on yield and cannabinoid profile.
Flushing was found to be ineffective in removing any significant amount of nutrient from the
bud.

Commiseration brother! I'm due to have that done on the 19th and I hope it works!
Green light shining on it!
All that just to tell me flushing is a waste? Took me an hour to read and now I know why I didn't like school.... didn't understand a fargin word....ha ha!
