I hope some sense can be made of this. Sorry i dont have lab tests. But i will say my buds still grown with hps now are more potent than ever. So grower skill and environment are the most important factors. Not light frequency.
Not expecting lab tests! You have far greater experience than me, it would be foolish not to consider your input carefully.
I am happy to defer and switch to all HPS now. I need new bulbs anyhow. Lets figure out my order and I'll get them in this week. (2) 600W + (1) 1000W
As far as grower skill goes, I have an idea. I'd love for you guys with experience to be a part of this lab. I am posting up vids of my setup. I can control every environmental setpoint. We have 1 grow to get this 100% dialed in (I have 6 plants fully vegged ready to move in) and our next grow will be the landrace seeds I purchased earlier in the thread. I'll document everything and hide nothing. If a problem comes up, we can solve it as a team.
Together I think we can push the boundaries and better understand the plant as a whole, regardless of each of our motivations.
Once we get thru all this, we have lots of other things to test too. Like today my wife asked me to verify the CBD she bought online was legit 99% CBD (and not CBDA, or corn starch,, etc) That kind of stuff is interesting to me.
So what are our setpoints? Here is a list including my standards
Temp - 78 to 80 day, 68 overnight
RH - changes throughout the grow following VPD chart
CO2 - 1250PPM
Light - 2200W @ 12H on 12H off
PH - 5.8
Nutes - I typically measure in PPM. Nutes should be it's own post
Res temp - 68*F
Water change at least once a week
H2O2 - at start of run and then no more that 10PPM the remainder of the run.
