Indoor / Outdoor Selection Tool?

[Bass Akwards]

A small, 2 column-inch, filler blurb appeared in the Vol. 5 / Number 5 issue of "Skunk" magazine in an article about problem gardens credited to "The Rev", ( the magazines' resident grow-hound ). He says that a side-by-side test showed some strains "just don't like" CMH lights. The strain, or strains, weren't named. Details were scant, he evidently used an organic soil mix with identical clones under "several different light sources".

Given that so much of the current commercial gene-pool was bred indoors, under halides and HPS, it wouldn't be surprising if some strains were unable to handle the spectrum and/or UV levels of CMH lights.

Has anyone else noticed this effect?

Has anyone tried to run Outdoor strains under CMH?

Could "CMH response" be useful as a seedling screening tool?

Is it possible CMH can shorten maturity for Sativa / Haze variants?

i'm suprised you've had no responses.. especially with regard to to shortening and giving better growth for Sat/Haze/Narrow types

you might find this thread of interest.

No Rhyme or Reason ...

Thanks for the link.

Some interesting takes on the science there.

There's no rhyme or reason why certain threads get attention.

We posted the same question on the CMH thread, and it was ignored.

The only complaint we've seen associated with this bulb is an increase in the quantity of leaf matter. Perhaps it would be a useful test to grow a strain known for a low leaf to calyx ratio.

Since we're not able to commit to a possible 3 or 4 months of 12/12 ( if it doesn't work ), a test of "low leaf" strains would be easier & quicker.

Any suggestions for a low leaf, SOG, strain?
