Very interesting @baudelaire,
I look forward to those threads coming soon. I was imagining they could be mounted on bar array and pendant mounts as you mentioned, and I can imaging them been used in verticle boxes in the future similar to the verticle cool tube set ups where the lights are mounted vertically in the centre and the plants grown similar to the coloseum design grow box style set ups.
I thought the photo of the Janis plant you posted had some blue spectrum in the photo, I also make use of MH supplemental lighting during the strecth phase if growing with sativa dominant strains as you say it helps with keeping internodal length shorter and overall finishing height. @MadScientist See i’m not the only one !
I was doing some breif reading on the cob chips just earlier this evening, your post sparked an interest in me. so I understand the driver or power supply method now and the string etc which removes the use of solder used on standard LEDs (smd). I have heard a lot of complaints about those where the solder gets hot and individual leds part company with the circuit etc That has been what kept me off looking into them for a long time (reliability), but technology advances fast if the market is there.
Yes I am capable of hobby electronics to industrial level rewiring of buildings etc building my own power boards with timer delays etc for turning on 20 plus hps lights from one power distribution board to keep the ampere load down at switch on time etc
The green spectrums are something not visible to the human eye but I have read a little about it years ago but there was nothing really available at that time, and was contradiciting what I then understood that the plants do not react to green light. Difference been obviously the visible green light to humans and not the green spectrum in the ultra violet range. I have seen 1 bulb years ago that was in the green ultra violet spectrum used as a germicdal tube for water (Koi pond fish related item). Thers a lot more to it than meets the visible spectrum of the human eye
The picture of the 4ft looks to be solid from tip to toe so to speak so yes I would concur that they do grow rock hard nugs by penetrating the light into the canopy, and by the look further than the avergae 8" of a 600w hps
This is something i’m going to have to start seriously looking into. I cant say I have ever seen the diy kits ever marketed on my side of the pond and all I have seen on sale in the shops tends to be from your side of the pond and ready built blurples, but where there’s a will there’s always a way. I have seen ready built single cob untis in the £1000 - £1500 range in some grow shops recently I have seen individual cob bulbs available in some wholesale electrical retailers here just by doing a quick search, luckily my freind owns one and does a lot of trade with Asia
I await your thread now with eagerness and enthusiam while I do some more research of my own. Much appreciated and thank you for taking your time to post.
