More blue light, shorter nodes, bushier plants?
I'm still very new to growing, but since I have started, all of my grows have been with 6500k PLL lamps for veg, and a Pro-Grow 180 for flowering. I later added some different lighting (3000k CMH then 3000k PLL) for the flowering phase, but still use the PG 180.
Anywho, I found that vegging under 6500k with the lamps close gave me squat plants with tight nodes. One of my plants (70% indica) had nodes only 1/2 apart. Even my mostly sativa Neville's Haze had fairly tight nodes until I moved her to the LED for flowering.
That being said, do you think it is possible to control the stretch you often see during the first few weeks of 12/12 by using the same type of lights used during vegging? That is, continue with 6500k until the initial 12/12 stretch is almost done?
Just wondering "out loud", may actually try this to see if it works in future grows. Really want to experiment with this for some landrace sativas I will be growing very soon.
Not sure i am new to growing also but i will be watching this to see so let me know what happens if you try this.
plants naturally grow 2 to 3 times during flowering.
Yes, but most of us also switch the type of lights during flowering, so there could be two factors involved: going to 12/12 and changing to a redder light. I'm talking about keeping the same type of light used for veg during the initial stretch phase of flowering and then changing.

During veg if you add more red it will keep nodes closer and prevent stretching. Have bushier plants.
During flower. Blue spectrum will prevent stretching. Blue end of the spectrum has.the most photons and promotes terpen production. In turn more trichomes.
In veg blue / red - 60 / 40
In flower blue / red - 40 / 60
Not too sure about the red keeping nodes closer. My nodes have been pretty close together under 6500k alone, some as close to 1/4-1/2" apart.
