My apologies. I posted the wrong video.18:15, lettuce graph referencing study, then he suggests they independently verified results with a bunch of other crops, none of which are cannabis
20:04, references another lettuce study
24:25 suggests if they can show these wavelengths are beneficial to other crops then fixture manufacturers will start using them, does not claim studies are definitive or about cannabis
27:16 talks about study comparing lettuce to cucumber
29:30 sites anecdotal evidence from his side by side grow suggesting increased blue light will shrink a plant then says that far red can compensate for this with cannabis but provides no evidence or reasoning and goes right back to citing lettuce studies
What you are saying about diode count isnt that simple. Diodes come in different sizes and can handle different wattages, the samsung diodes on my timber cob lamps handle over over 100 watts each but they are far bigger than the little samsung diodes on my hlg and kingbrite boards that all use far less power.
Again, the actual studies he is citing to back up is claims are about lettuce, he is theoretically applying those results to cannabis.My apologies. I posted the wrong video.
Correct. But those diodes are highly inefficient. Were talking apples and oranges.What you are saying about diode count isnt that simple.

He has been studying cannabis for longer than any university I believe.Again, the actual studies he is citing to back up is claims are about lettuce, he is theoretically applying those results to cannabis.
I get where your coming from here. and I've also thought about using say a bunch of 1000's in an array of sorts. I certainly was at one time probably the best overall solution, no doubt. But the array's have largely solved this problem for us. There' even better than using a bunch of low powered quantums like you suggest.I agree with the first part 100% but my main difference is that I'm suggesting solving the issues you bring up with several smaller fixtures rather than a lower number of larger fixtures.
You can still buy roughly two kingbrites for the price of one spider farmer of the the same wattage, I agree the warranty part might be a hassle but is it really worth that much more for a spider farmer?
watching it.... No doubt Far RED & UVA/B is extremely important and making certain flavors, oils and terpenes even possible. It's changing the way we grow cannabis, because it can now be customized.My apologies. I posted the wrong video.
There are just to many to list imo. But concept wise.I think this thread has lost the plot, everyone seems to have missed the context. My suggestions and arguements are in the context of the ops question what are the best cheapest kind of led full spectrum light. Suggesting lights that are 2-3 times more expensive just to have some debatably useful bells and whistles misses the point. If the op asked what light has the most features for the money or the best warranty for the money my responses would be different.
Yea, I agree those are the most important considerations, no doubt. As long as the engineering specs are up to date with the config, and it's a full spectrum light, I really think there are lots of good choices out there right now. The market is fairly saturated with good products. Some are going to be a little more efficient than others, or run a bit cooler, longer shelf life, ect...There are just to many to list imo.

More diodes per watt.
Full spectrum
Best spread
Cost per watt
I think migro has a spreadsheet somewhere that breaks a lot on the market down.
Yes the introduction of far red really helps with canopy management. By that I mean making a more even canopy. Starting to see in many grows the added far red is allowing lower growth to catch up thanks to the shade avoidance response it elicits.Yea, I agree those are the most important considerations, no doubt.

The LED game is undoubtedly in full swing and overtaken the traditional market. It's a new way of doing things.
Most of the bells and whistles simply revolve around features, and higher efficiency. The basics can be obtained for much cheaper and will still yield outstanding results.
Ha ha is always turns into thisThis is a job for @1diesel1 thread (an absolute gem imo).
L.E.D. Argument Thread For Dummies:)
I’ve put this thread together for all you passionate led hardcore members. When your in someone’s thread and decide you don’t like what that guys saying about you, his, hers, there’s, them, etc led’s and want to highjack someone’s thread to get a little pissy this is the place for you. Rules No...www.thcfarmer.com
I have yet to be able to recall a single LED thread that doesn'tHa ha is always turns into this
And what is the cost of the Ozram far reds. How many are in to board the varied fixtures. Fluence spider 2I are down to 898. Gavita 1700e are down to 998. I really would pay an extra 1k to not have 34 racket straps hanging down in a 10 x 10 tentYes the introduction of far red really helps with canopy management.

The UV on the other hand still best supplemented with florescent tubes
