Gypski, hope you don't mind my anwsering questions here, not looking to jack your thread.

Yes Bigsby, noodling things is good and so is varying light intensity thru out the grow. Vegging plants need less light but blue dominate, while flowering needs much more intensity and more red dominate. I would not go down in amount of light for end of flower tho, I might try adding a light that could give better trichome finish. Adding some UVb (use great caution with this) or look to change the spectrum for the last week or two, using a bulb that is in the 10,000k range. Something like a PSMH, or CMH or even a MH in that range. It makes a big difference with getting trichs to turn amber.

I started it for that reason, just to get different opinions that I can try or relate. :thumbsup:

I think this myth got started by someone not understanding the use of 36-48 hours of a dark period between vegative and flowering. This btw does have an effect on how fast a plant makes that transition.

Hope this helps and is maybe some food for thought. :thumbsup:

More food for thought is that this dark period before flowering is strain dependent.


I've alway's used 36 hours of dark before shifting from 18/6 to 12/12,

While I don't have a full grasp on it's effect, I can say at least for my blueberry strain it was a detriment.

I did a blind grow resulting in high stretch, and 2 day's delay in the onset of flowering in the "Dark cycle" girl

The 2nd plant was simply swapped to 12/12, and actually received an EXTENDED light cycle! around 24-28 hours, most was under the blue of the MH (14-16 hours), the latter was under the red of HPS.


I'm not going to actually log this grow, so it's just speculation See sig line.

Thanks oldmac, I do have a grasp of the basics... I've been reading up on some of the advanced techniques with light and scheduling and have been wondering what is valid and what is not. Thanks for the clarity on the 36 our darkness issue.

PSMH - is that a conversion bulb? If I could run a CMH I definitely would but unfortunately it requires a coil/magnetic ballast or a rarefied electronic ballast neither of which are in my arsenal.
