So i did something with the QB244 that you cant do with a lux meter. Thats induce potassium deficiency in the plant through colder temps. The plants will actually turn purple and darker purple every place your light penetrates. Which I can tell you from my experience doing it. I was able to run my entire grow universally with only 6" of movement from the lights up or down. everything else can be done by the dimmers. or raised platform. I had stuff on the bottom turn purple. You can actually find a really nice mark with this method for penetration of your lights and configuring them. Like I learned they were better run vertical vs horizontal for penetration? idk why but it was just better! But I run 6 of them per tent in the 2 with qb244s. Its been cheaper for me to go with a different quantum light since I switched. Which using that same cold technique while it was cold found some alternative lights to supplement my expansion and is about the closest thing to the qb244s i can get. Total to match them is only about $85. So its relative to the diodes i guess.
The only true way I believe to tell your light coverage and penetration is running a grow like that.
some examples
note: white spots are not PWM but remnants of a dried foliar spray i use.
What i learned in this case was that strain on the left was getting more than enough light. The plant/strain in the right on the corner could stand a higher intensity. Thus I shouldnt have grew these plants together. But it gives a perfect picture why i chose those to cross these 2. One on the left can grow in extreme colds and take really bright light where the other one can handle the same and can handle more light with the induced defect and gets rock hard nugs but tends to stunt its growth until it induces full on failer. Those plants actually vegged in a qb244 tent and finished under the cheap "quantums that are $85 a pair and they were only being run at about 70W per light. with one supplemental screw in LED bulb i was using to get the low hanging fruit and move around the tent daily.
Is lots of things you can do to be creative. Each strain responds differently. Its not a condition that universally can be achieved by some. for me its reserved for the fall-spring grows. or finishing off summer grows. But to be fair im all about cold weather genetics.
Now if you notice the penetration with the cheap quantums on that tent. we go over to the qb244 tent and we see the penetration all the way down into the canopy turning yellow. Im not sure with the photos are of the finished aspect will have to find em. But same failure far greater penetration.
I never ran any qb244 over 80% most averaged 75% power output. What we can see with the QB244 is a clear penetration line well below the half way markof the tent and cannopy. That its not just the most exposed buds with the cheaper option. But dang near full penetration which we can compare the same strain to the sun and temps.
Which is why i love that strain. Cause it lets me create a real world benchmark to my equipments performance through simple condition changes. But it takes enough control over the environment to truly know you are artificually inducing the right conditions vs other failures.
So if my results are anything just hang em with yo yos. Most i had to drop it down is maybe 6-12" and after veg they could ride full height with no issue im sure one could move them all day for max effect. But i honestly dont believe its entirely necessary.
