What about those of us who don't know or particularly care about wheatgrass, but feel that since there's no evidence, this isn't science and possibly shouldn't be on a scientific web site?

BC,

I appreciate your even handedness in discourse. I am not a scientist, but rather a musician and familiar with different standards that would be considered useless in this setting.Things like expression of feelings and renumerative results of performance.

As I did a little research though, my old friend at the Center for Disease Control in Atlanta, a mathematician, reminding me that "math is the queen of science", has indicated, while not double blind tested, that the concept of positive correlation is very real and useful in the process of determining objective scientific truth.. If he is not in error, then perhaps, what has been discussed here the last several weeks may be the initiating observations that may spawn more definitive study.

In either case, I'm more interested in production values now...which are quantifiable.

Hi SteveD,

I was also interested in production values regarding growing wheatgrass. It's tricky to get consistent quality trays of wheatgrass.  They require frequent watering, the amount of sunlight/light affects how fast the sprouts grow, soil amount and quality is a big factor, and when the tray is harvested and juiced I think has a big influence on the nutrient content.
I've noticed when the sprouts get a bit too much for the tray/soil amount and start turning yellow, the juiced product and effect definitely suffers, and there is only a couple days' window before it gets like this. There may be a wide number of factors affecting nutrient content.

That's been my experience. The potency diminishes quickly after the 'bloom' of harvest has past. You can tell by the yellowing, but even before that there seems to be a wilting that happens. I also juice within 10 minutes of harvest.

I water once day, but the Sandra and Ken water every 15 minutes....Whoa, too much...but they have automation.

I've also noticed that if I plant for three successive days, and then there are three good days of sunlight, that all three trays will be the same height!

I am going to start measuring the yield of juice in ounces/tray (currently at 27.5 ounces of planted dried seeds/tray ) and see what the variables are to try to increase production values...Will report back.

Wednesday 3/11

Screwed up and did not plant on time today before sundown.

91 ounces of seed already starting to 'show tail'.

I can do better than that...

Production study:

I have 36 17'x17'  trays of wheatgrass in various stages of maturation.

Today I harvested 11.75 (dry weight) ounces which yielded 8       fluid ounces of juice- from one full 17"x17" tray
Then   I harvested     8.5 (dry weight) ounces which yielded 4 .5  fluid ounces of juice- from one half (diagonally) of a 17"x17" tray
                                                            and consumed 12 ounces and saved .5 ounces

I also notice for the first time in two years that there was a touch of mold at the bottom of one of the trays in areas where the seed seemed too compacted and did not appear to be germinating as well.

Steve, this is not a blog. No-one cares about your wheatgrass regime. It's not adding anything to scientific knowledge about wheatgrass.

I wanted to know if anyone else has positive experiences with wheatgrass

Cliff,

As one of the people who have addressed the question asked when this thread was begun, how is your production today?

Production study continued:

 Friday March 13th first cutting of the day

 9 1/8 oz dry weight yields 6 1/8 juice = one whole tray
 7 1/8  dry weight yields    5 7/8=              1/2 tray
    12 ounces consumed

Why the variance in yield in trays planted at the same time?

[SteveD (OP)]

Yesterdays cutting
20.25 dry oz/ 12.5 fluid oz = 1.62 oz yield

This morning's cutting
16.25 dry oz/12 fluid oz= 1.35 oz yield

20.25/16.25 = 1.25
Why do 1 1/2 trays yield 25% more dry weight than the next?

1.62/1.35= 1.2
And more importantly why does the why does one cutting produce a 20% greater fluid yield/dry ounce?

I second that motion. Stop spamming.
