Some of the photos appear to show a supplement light in the red spectrum.
Curious as to any specifications you may have and how it is working for you.
I am a newbie at autos, my first couple go arounds have been a mixed bag of results.
I use three groups of lights, feed lights, trigger lights, and supplement lights to assist feeding due to sativa and indica preferring separate peaks in where their sweet spot spectrum is.
Auto flowering plants are not responding the same as the photoperiod plants I am used to so I am gathering all information I can find whether it has obvious applications or not. Only time will tell.
I grew a photoperiod Jack Herer and liked it. Small for a photo period with a three ounce yield, my second planting has two in the same 18" container. Some small plants get up to five in a single container. This greatly increases available harvest without increasing the square footage of the bud area.
The current auto growing is BlackBerry Kush from Dutch Passion, it looks to finish at about four feet, same as their auto Euforia, only with fatter buds. Lotsa room and light needed for these large 90 to 100 day autos.
