That has little value anymore to me. You disagreed too often for the sake of disagreeing, your strawman attempts are by definition fabricated for the sole purpose of disagreeing. Most normal reply I've seen from you in a while so let's give this a try.
We already had discussions about hps vs t5. It's no secret which I would recommend in general. I've also been clear in the led forums about the possible effects of blue that a lab test might show. I also explained why it would logically then still make sense to use the higher red and supplement with blue when and where needed once proven to be effective.
The difference between the effects of cool and warm color, and the tradeoff it appears to involve in certain situations, is not new or unfamilar for both hid (mh vs hps) and T5 growers. It's a fact you and others picked the blue cobs thinking they are more "efficient" and that has nothing to do with riddle's choice for T5. Every bit of possible advantage of blue will now be cherrypicked over every well known advantage of red. It's the type of stuff we used to troll together. The same reasoning for using PK boosters.
Above all, still plenty of blue in the for horticulture better suitable cobs. Essentially by pretending the
relative amount of blue was my main argument, you post another elaborate strawman attack.
I haven't seen a cob led grow here yet that surpasses the best T5 grows I've seen over the past decade alone already. Just happens to be the case that the admin of the main dutch grow forums (replaced whazzup) is a big t5 fan. I'd pick led over T5 personally, but not how you use led. I don't know rm3's spectrum, I could probably suggest improvements if his goals was (to claim) energy efficiency and max gpw. In his case, not using his space to the limit tells me that is not his goal. Neither is running highest intensity. Sooner or later he and other T5 will switch to led tubes (strips) and then... well, see my posts and comments on the effect of total photosynthesis of a 3d plant instead of thinking net photosyntesis rates of a single leaf.
Blue light is much more absorbed and penetrates far less. At the same time, again see my posts about diffuse lighting, instead of causing photoinhibition at the top, riddles diffuse light from different angles... If you understand the research I posted and my replies on sts comments, or just sts' comments alone this should all be obvious. Whether he realizes it or not, riddle is in a way ahead of the led guys with the placement of his light sources.
I know you can grow a decent plant too, but let's be honest, the majority of the biggest led fans should spent time learning how to grow a plant, which riddle can help them with much better than most if not all of the led fans. If you were genuinely so concerned about noobs getting the right info, you'd be putting all this effort into teaching the led guys the basics they often so clearly miss.
Have a great weekend.
