wat do the user manual recommend. if ur in veg why would you activate both veg n flower lighting. What does your manual say. can the unit be run with both spectrums without burning your boards???So, I am running an AgroLED 432 (265w actual). It has the nifty two switches: Veg and Flower. Sine there is only absolutely inconsistent information about LEDs out there, and how people use them, I have basically started off the 18 hours with one hour of just blue, and the rest of the 18 I leave it with both the Veg and Flower swithes turned on. Lol obviously with both on it is very intense light in there. Things are going well, and I do not have any plants that look like they are complaining.
What I have found out is that on Veg, the blue lights, it is not nearly as intense of light in there, so I am curious to know if when the Flower light is on as well, does it basically wash out the blue enough to be effective as possible?
Anyway, the idea that I have is to stat on the 18/6 light cycle, but I'd like to do at least a quarter or a third of the 18 hours using blue light to increase my veg growth to hurry and fill my screen so that I can flip. Basically start the day by lowering my LED (sine the blue is far less intense), and leaving only the Veg blue on for several hours. Come back later, and raise tot he height I like for both being on, turn them both on, and use them both for the remainder of the light period.
Any thoughts, gripes, complains? Hell, any other ideas? I am in my SCRoG and I just did my first tucking last night, so I am getting more and more amped to see it fill up. Worried that the intesity of both switches being on cuts down on the avaiable blue light the plant can absorb since it is still in veg stage.

Be careful how close you put the lights, leds at close range can cause bleaching to the tops (in flower).
If your leaves are drooping, raise your lights until you see them reaching up. if they are reaching up too far then lower lights.
Some strains react differently to the ratio of spectrum lighting in veg, more of a trial and error scenario.
Blue is not going to look as bright (intense) as red. But i would use both in veg, and in flower first couple weeks use both, in middle of flower all red, then finish with both.
Use both settings at the same time. Full spectrum is good for the plants growth and u don't lose any blue intensityNo joke, the only directions or "recommendations" that it gave was to keep it a minimum of 12" above the canopy. On the box it basically just says that you can use this one light through the whole growth cycle. Below is a link to the light that I have in case you know of some place that I am missing for imperative information.
What I am trying to figure out is what will my plants benefit from the most? Should I blast it with all the lights and all the intensity and glory it has? Or should I just leave veg on, which is considerably not as intense, and move the lights closer? Where the light since at right now, if I am only going to use veg light, I need to move it down a few inches to get it a bit brighter on the plants (only moved it up because of the intensity of both switches on).
Straight up, I cannot find any technical stuff on this, and honestly, every forum you go to everyone has their own opinion (which I do like).
I guess an easier question is during the veg stage of the plant, does it benefit more from only the blue veg lights (since I do not have one of the newer LEDs that allow you to adjust the intensity level of the different channels)? Or does it benefit even at that stage from the red part of the spectrum as well?
Ok i will tell you this, blue light on your fixture does not have less intensity, your human eye perceives it so. Our eye adapted to see yellows, greens, oranges and to some degree reds brighter while blues look dimmer to us in comparison, especially when the light we see is getting closer to 400nm, on the other end of the visible spectrum, light looks dimmer as you get close to 700+nm.After re-reading your post, this was another thing that I was kind of worried about. Since the blue isn't as intense, if I am running just blue Veg lights, I get the light down to the recommended 12". When I turn on Flower with the Veg switches at the same time, I strongly feel like I need to raise up the light several inches to keep from harming the plants with the total intensity. I worry that since I am raising the light further from the canopy, I will be losing too much intensity of the blue light and there is essentially only the Flower lights intense enough to make it down to the canopy.

Run them both. Veg and flower. Those blurple lights need to push out the wattage.
And when you have a couple of grows get a QB board or strip fixture. You will be happy you did.
I was just about to say something similar to this...Thanks Crim...Ok i will tell you this, blue light on your fixture does not have less intensity, your human eye perceives it so.

Thats just how our eyes work. Even with 2 lights that have exactly same intensities, where one emits 420-440nm and other 600-620nm, the 600 nm will look brighter to humans.
Thats why lumen calculations doesn’t work with plants, plants “see” the lights that looks dim to us brightest, except 620 nm, we see that quite brightly too, not as bright as green but bright nonetheless.
