A lot of the commercial blurple lights are a 65+% Red for bloom and 30-40% for veg phase. 👽
It depends on the plant, but the general consensus is blue is for veg and red produces denser buds, but you need to have a mix good mix to allow the plant to absorb light from all over the light spectrum. So there is no real answer, it depends on your grow environment, light quality, strain, and nutrients.
During a long photoperiod, a low Red - Blue ratio is preferable to make more developed long cuttings.
During a short photoperiod a high proportion of blue light will improve the medicinal value of cannabis in terms of cannabinoid content.

So the big debate.
As I understand the blue lights represent spring and the red lights represent autumn.
You can grow for the first few weeks using blue only but apparently red cN help root growth.
You can also grow for the last few weeks of flower with red spectrum only but I do believe that you should use dual spectrum all the way.

Hey bro You typically need more blue than red in veg stage and more red than blue in bloom plus a few others. It's very complex. The best explanation I've found is California Light Works website it has some good info and reading material. They tell you which colors of the spectrum plus uva,uvb and infra red are best during each stage of your grow. Their lights are top notch but very expensive but give you the best control over the color spectrum with programmed controllers. Hoping one day to own a couple of their lights. Good luck and Good reading.

Defoliation for better ventilation?Should I defoliate/prune to ensure better ventilation? I am going to flip the plant soon. It is quite bushy with big leaves and sometimes it is difficult to water it as there are a lot of leaves down there.
And when is it better to put the net? Before of after the flip?

My stash is all but empty. Also, should I defoliate again?

Northern Lights Auto, quite short and bushy, fan leaves shielding light - should I defoliate?First time grower with a quite short Northern Lights Auto in week 6. The fan leaves seem to shield a lot of light from the inner leaves, also touching ground. Should I trim the fan leaves? Or should I keep them, since it already seems stressed enough for it's short life…

Defoliation late in flower on Auto'sI like to defoilate, If I were to pick majority of the fan leaves off of these plants being Auto's, will they react or stress too much? I like to defoil near the end of flower to really push all the focus to the budsites. Happy Growing!9 months ago
