Twilight LED Grow Light Questions

[PSUAGRO.]

Government prohibit to grow hemp/cannabis/marijuana in China.

China is top 5 HEMP producer/exporter worldwide.........................USA is #1 importer, because we still classify it as a schedule I federally . ........ Some US states have wised up and are allowing farmers to plant it i think?

great plant, the major cotton lobby can only hold it off for so long

@twilightled2015
You lied about deleting A51's company name from your sales pages.

There's plenty others, but you get the point.

There's options for 720nm-740n that are quite reasonable. 30% efficient+. It's just the 670nm - 725nm, and again from 725nm-1150nm that is bad.

@SupraSPL to your knowledge, what's the best far red you know of?

For me, it's either the Cree XPE or the Optotech, both are about equal in terms of output per watt used.

Do you think incadecent bulb may be cheeper and better option for Beyond 725nm . They might be even more reliable than those bad Epistar IR's

I happen to like Kale!

As a matter of fact, YES !

In this case, it would also make sense to use dimmed incandescents, and theatrics filters. While incandescent has a significantly lower R/FR ratio than the 4000k 80cri spectrum, pure 730nm has significantly lower R/FR than incandescent, basically 0.

As a matter of fact, YES !

New Light with Powerful IR Spectrum

Not as crazy as it seems
Granted, the scale is satirical.

It is E27, adjustable Infra red spectrum. Put your own bulb.
Efficiency critical for us. As always we must use Meanwell PFC 90+% efficient power supply to power such incandescent bulb with reliable DC power

Is that using the old style Meanwells?

That's the 10A version, I think. 99% efficient (on matched loads).
