Weird grow space a proper scrog and a diy board or a strip light would be my choice. You could also fit a nice vertical scrog in there, but it would be a lot of work.
If you don't want to scrog then vertical strips might be an option to think about.
Which was what you were looking for. Short term memory something like these? https://www.futureelectronics.com/p...es/bxeb-l0560z-30e2000-c-c3-bridgelux-8115969
Yeah I am looking for something along those lines. Ideally I want something cool enough that the plants can touch it without issues. The space is only 18"wx28"dx72"h, and the plants can easily fill that floor space. Think of it sort of like a vertical scrog with an intense top light.
Its just that using a full sun board or whatever on each side and then have a light on top would add up to a silly amount of wattage for the space. I was considering a very high efficacy 24V tape light to surround the plants. I have seen some that claim 150-160lm/w and they have them in a variety of spectra. Those boards you link to look good too, but can I get them close to the plant?
Even if you can touch the diodes with your hand does not mean the leaves are fine too when touching. The leds I have are only warm to the touch (42-46C) but any leaf touching it will still get white burn marks.
What does "Rspec" mean anyway? HLG's website doesn't explain it anywhere I could find.I have a HLG135 V2 Rspec in a space like that and it does really well with little heat, you should do really well with a HLG96 and side lighting.
Samsung h-series strips (lm561c diode) would be good https://www.samsung.com/led/lighting/led-modules/ambient-light-module/h-series-gen3/
and lm301b/h strips too. It comes down to the price you can get them. Lm301b is the efficacy king, but if you can get many more lm561c for the same price you can drive them softer and get the same or better efficacy.
It means Red Spectrum, because they add red diodes to the white diodes. They also have a BSpec, which is added blue diodes instead of red.What does "Rspec" mean anyway? HLG's website doesn't explain it anywhere I could find.
Yeah, the 660nm reds are there to up the efficacy mostly. I'm not sure it's worth the extra price, but I can't know for sure.
Ledgardener.com has info on the strips. I'm not sure if its upto date on all developments now, but there is good info on bridgelux, and samsung h, q and f series there.
I do have to wonder if they're really all that different. I think maybe some of them have UV/IR/RED, but I have so much more to learn about DIY grow strips.
I am thinking I'll aim to get our first chamber fully built and then expand as I can afford it. I'll aim first to get together the money for the QB96 V2 and a driver for it. After that I'll add in improved side light as I can afford it.
Would a cheaper driver work as efficiently as a MeanWell driver? Also, do you have any idea if one can run a DC cooling fan off of an LED driver?
