I think this is incorrect!!! If you have been following along with sal and all his post (like I have). He has pointed out that his research has proved that the photoperiodic response in the MJ plant is mostly controlled by the Blue light duration. Not phytochrome!

Here is another example of the PAD manuel totally disputing that article..... The PAD Manuel uses KNOW uvb light at all and can double the THC content at a minimum by using 24 hours of light...

My next post........ I will tell you what the manuel doesn't say about our favorite plant.:thumbsup:
I was just having a discussion (read argument) with my partner about PAD and what we might do with it. One of the problems we have is the lack of info that has been forthcomming. It would be nice to see some numbers for the technique and results of it's use. Even without it, we are extremely interested in it, and have made the decision to build a new LED light that has the reds and blues on separate circuts to utilize the advanced PAD technique.

As to photochrome, these protiens play off 660nm light vs. 730nm light and are responceable for the under canopy stretch etc. From what I read in the PAD manual that is exactly one of the plant's functions that are being exploited by PAD. More possibly photoperiod is more a function of blue light, but that 730 is some sort of plant trigger.

While I believe that trichome rippening can be accomplished without UVb (Dreaded Hermie hit amber trics with just red and blue!) we have had a few experiments here that clearly shows it's effect on trichome maturing. I still have a 2gm/plant finished weight differential if I don't use UVb thru out flowering so it's effect may be more then just turning trichomes amber.

I'm looking forward to more info and finished numbers to see how fast or deep we jump into PAD.
