I was thinking the same thing, in fact I typed up a post almost identical to yours, but my computer crashed before I could post it and I didn't want to retype at that time. I am still curious about this though.
All that light lands on something and turns to heat. One way it turns to heat is when the plant transpires and thus the heat becomes additional humidity.
All you are missing is "Even considering the conversion of some photons to heat, the difference is significant." Change "some", to "all" and there you go.
RH is a big factor.
You can run CBX 3590s at 25 watts with a 700 ma driver, as I recall that is 64% efficiency. Gets expensive quickly as sqft ramps up though......I'm planning on running 1050 ma (~40 watts and 61% efficiency) and still wince at the number of cobs needed.....and the $$$.
I went with 50W per COB and it was still plenty spendy.
I'll post some photos of my recent mono-cob experience if you like .It was by far my best run yet. I don't know all the techy bs but it makes sense to me. Adding a few more watts in a wider spectral range. Who wouldn't do it? Unless money was an issue cause it does get pricey adding them in.
I was just making a joke at the disco effect Mono's have. I myself was thinking about putting a sink on an aluminum pie dish with some Mono's like a 3(630)1(730)4(660) for a fun pun pi pie.
Nothing I've grown under COB LED has acted like it needed any supplementation at all.
It's also not hurting anything. I just chopped some of the largest buds I have seen in my life under the mono-cob lights. I used the monos for veg and cobs and monos for flower.
Dude you are the least organized person I have ever seen. Lights looking good but my OCD would t let me finish the video. Lol keep up the good work. Oh and I also ran my angle the other way arounds with the sides up. Don't thing it matters
200w kit $369 and 250w kit $469. I haven't made the Massive Passive kit yet but will once a make a light that requires that sink.
What are those kits comprised of?
cobs, holders, reflectors, heat sinks and driver and I'm gonna add the M screws
If those prices are for top bin CXB3590 and Meanwell drivers, those are some damn good prices. Is that what's in them?
Yes indeed. I've got Cobalt drill bits that are better than Dewalt as well I can get what ever size you guys need. I used to have a Industrial Tool Supply Co.
