I think of spectrums for plant growth in terms of two spectral ranges of phytochrome reception, but really it's three. I tend to think of Red and Blue behaviorly as one factor and the Far Red 700nm to 800nm as another factor.

When using PAD, tight volumetric uniformity results in a tight genetic (mRNA) responce ranges (reduced genetic bandwidth).

As a specialist and a well practiced researcher I'm sure I'm much more bandwidth critical than most.

In one respect this is like most growing, you get better results the next time arround by learning how to dial into your plants demands and responces to the environment you provide to the plant.

I hate sounding qualitative all the time, but I'm really just here to your perspectives and desires.


- I'm on those graphs next time, thanks Dog.

Take care, Sal.

UVb an experiment Quick background: I have been using UVb supplemental lighting for many years now and have always thought it added to the finished product in a couple of ways. I had never promoted it's use on these boards because I felt it was dangerous and had real potential to harm people. That changed a few months back on the other UVb thread, and I came out of the closet in strong support of it's use. Well some here who's opinion I respect (like Weezard) held the opposite view and those discussions led me Rating: 5
