Phytochrome is always in constant flux between it two Pr and Pfr states, and reaches states of photoequalibrium, even in the dark it cycles between the two states reaching an equalibrium due to the two rates of conversion between the two states.


So it's not really a question of quicker, it's more an issue of WHAT state of equalibrium the combined wavelengths produce and a period of time needed to reach an equalibrium state.

Hope that's not to Quantuum Theory for ya, but it boils down to tracking large numbers of phytochrome molecules and the numbers of the populations of Pr and Pfr acting within the cells.

I've considerred the condensation issue and concluded it would be an air handling issue and possibly adding a bit of adjustment to a liquid cooling systems flow, in order to keep the component temps above the condensation point, while still maintaining enough cooling capacity.

Take care, Sal.
salmayo Reviewed by salmayo on . HID Time factor manipulation I've been following the UV-B thread for a while. Cool stuff. Makes me want to get back into growing. But, what really gets me going is the Martian stuff and the light time factors for increasing tric production. I seems to me that, unless you've got a ton of cash for LED's or have alot invested in HPS setups already, it's really hard to get down to the magic 1.8 and decent yield. However, I have some ideas to get closer: Fluorescent Supplemental Lighting: http://kinoflow.com has HO Rating: 5
