Holy Grail Kush // Mataro Blue // Super AK

as far as i know, its just not needed. as @Crusty_Juggler said, it's a gimmick from back in the days. Buy a good full spectrum LED with even light distribution (i love MIGRO) and you can do everything with it. glhf

I like my LED, its full spectrum "FS" and its output is petty even on the reds and blue. similar to most FS LED outputs are now. Other lights in the brand I have "Medic Grow" also have Flowering/Veg settings. but they just make it more red for the stretch, but I kinda like the lights being more cool. higher blue range. I also like stupid simple and not flicking on settings for the spectrum to change. I enjoy one and done. Base how long you have the lights on and on what intensity/dim from the DLI output its giving. max is around 35-40 with out additional CO2 supplementation. With CO2 you can go above 40 but everything else in your grows need to be rock solid or its just wasted effort. I think CO2 is a massive gimmick and waste for all hobbyist growers. Now if you use HID lighting. CMH and HPS are the two bulbs you use. CMH for veg/flower and HPS for flower.

The veg change is a left-over gimmick from the blurple days when most diodes in a light were red and blue. Anything that isn't fully dimmable on each individual color channels with possibility for individual timers is just flash, is you can't fully control then turning up and down the intensity is plenty control. Any modern white light LED is great for veg and with formats like strips and boards it's easy to work with. Whether 3000K, 4000K, or 5000K, doesn't matter as long as I can crank it well up :)
