Thanks for bringing me back to this thread..as it has been a long time since I've read this and I have done couple of Lights studies of my own since then with significant outcomes between more blue Spectrum in flower and more red in flower. Where My outcome with a 31k CMH bulb over a 9lb Swiss clone resulted in 34 more grams of product versus The Identical 9 lb Swiss clone under a 42k bulb in flowering. Where these clones were grown under exact same conditions exact same soil exact same fiber pots exact same water. Where everything was exactly the same except for one difference when I started flowering them.... one was underneath the 31k bulb from the start of flower to harvest and the other one was under a 42k bulb from the start of flowering to harvest.

The test is not conclusive nor is it a scientific test but it was just my own conclusion and it was pretty significant to me.

More red

Where the more bluelight had a little more color a little more flavor and the buds were a little more dense. As where the red light had little bit fluffier buds just a little bit less flavor and a little bit less color... but a significant amount more in Final ready to use product....
As in a small grow and I didn't put anything extra to it no CO2 I grow organically is soil was my own organic blend there's no RO water so you know there's a lot of things that I could have done to increase all of this but I grow inside on the ho hum. I grow outside with vengeance and diligence as the sun is my God and the plants obey the Sun. This coming fall I'll do more tests as I have far red LEDs and many clones to work with. It's important to have clones from the same donating plant and it's also good to know what this plant runs like before you ever start a test like this. When I do test I will divide the room up so there is no photon Drift from either side. This will help me to conclude a better test in my mind to be more specific and accurate.
Thanks for the information. I read everything if they had to offer this morning. And there was really nothing in there telling me how they did their tests or to what end I became or how I could do my own lighting. As it was a commercial for selling their commercial LEDs. And not giving me free or even paid for knowledge of what I'm doing or what they're doing for instance. Only that they're working with this light spectrum of that light spectrum they're not telling me what they're doing or how they're doing it again it was a sales pitch. And that's why I liked working with Dr. Bruce Bugbee. His information is free and very relevant very informative. really the only thing he's trying to sell on the side is those Apogee inc. Quantum light sensing devices. Very fine device. I've spent too much money to get one right now. But maybe this fall I'll be able to pick one up and I'll build a light and have better idea of what I'm talking about when it comes to light density in my grow. As his Quantum sensors they start around 700 $800 to get one that's bottom mid-grade line.
Thanks pal
