I have to disagree. Simple maths will tell you which one performs better. If they are both receiving the same average PPFD at the same height, then we can work out which spectrum is more efficient. Once we've done that, it's a simple matter of grams per watt to decide which is the more efficient fixture.
Hey mate, a couple of interesting things going on there. So at that height it doesn't look like the RGB blends very well, but it doesn't seem to be making much difference would you say?
like the modularity 
these are the Random Dank seeds being flowered out to see what they are. Straight fire is what they are. Theyve been feed any & everything & took a few diggers too. Lol! But now i know they're worth a shot! 
The 2 Clone bushes are from when i topped the seedlings & cloned em. So RandomDank #1 & #2. 
plants seam to really enjoy the new CHPS. These are getting better. 
If you had a number of plants under the lights and all show that difference you would have a point. But with only one you are not in a position that qualifies you to make any assumption. Science doesn‘t work like that. You need to find an average and remove the outliers first.
By Ryante. Go to the other thread.
Because if anything i want to slow the growth not increase it rn but thats not happening a chance in hell. Its a monster. Still in a 3 gall.
Thanks for answering.
Really? You should try running them close for 1 week I bet you will claim some burning or light defeciency like you have before. "I don't want them to grow fast" said no grower ever except hybridway2
I don't know man the first experience with Meanwell I had was pretty bad. Some component in the driver blew up after a month and the LEDs were just flashing. No brand is perfect, but I still have plenty of Meanwells that work.
Ya I agree. Doesnt even have to be same height or PPFD, just that PPFD and yield are recorded. Then you can figure SPD effeciency on a g/PPFD basis.
Asking a scumbag adult who clearly lacks social skills if they have a brain injury is not an insult to all people with brain injuries.
That's right...
By angling the hgl you are taking advantage of rhe modularity. If the modularity is not going to be an option in the future, it would be prudent to flatten them out so there is not a false benifit given to style.
Agreed, that's why im not pushing any assumptions here. Also why i will do another & better Side by Side with more attention to detail while documenting so everyone can see everything i see as we go. That test will also be done for Stephen whom i feel got the shit end if the stick with the gnats. Only pott to have them. BTW, He did not ask me too nor mention any hard feelings over the matter. Pretty sure he understands that this shit happens in real world grow environments w/ real world distractions & responsibilities.
Was practically strong-Armed into close growing early into this by HGL (jk kindve) & you are right, exactly the results i got on both sides was unhappy plants, both sides were damaged & had to recover.
I have some sense of smell left, but most strains smell all wrong to me now... exodus being the exception, doesn't smell like cheese to me but like sweet things.
