Happy Thanksgiving!
Another DIY LED update. I made a plastic container based grow space. I used Samsung H series LED linear modules this time. This module was announced in Summer 2016, but it started to ship in October. This Samsung basically beats Philips XF-3535L (I posted about this previously) in all aspects. It has amazing efficacy (187lm/W), even higher than most COB LEDs. I haven't calculated the PAR efficiency, but I'm pretty sure there is no commercially available grow light with this high efficiency. It is a bit more expensive per light output than COB, but it is easier to assemble, and better for a small area. Also, it provides very even light distribution. It costs about $60 to cover 2-3 sq. ft.
I built this for pygmy Drosera, so it is targeting relatively high-light plants. Last year, I was using much weaker light (PPFD of about 70-100 micomol/m^2/s). Surprisingly they did ok. I doubled the amount with this H-series. So we'll see how the plants respond. It takes about 1 hour to assemble.
Here is the link to my Orchid Borealis blog post.
This is supposed to be Drosera dichrosepala ssp. enodes from Scott River. It is with the previous weaker light.
