If you looked at a SDG of a hps bulb you would see < 10% blue > 90% yellow- red. Tried and true, so why have led mfgs been reinventing the wheel?

Chlorophyll B needs ~ 500 nms, an important spectrum missing from most LED lights. Why led manufacturers are not following hps is beyond stoopid. Do your homework Buyer beware

Yes, i agree that green 500-530nm is needed in the LED lamps, but should not too much, bty warm white 2700-3000 LEDs also offer very high green spectrum.

More than you realize. Probably 40% green-orange, 40% red (~615-630) + 10% far red.

Cree EX-E Neutral White and Warm Whites +~ 10% 660-740 would do it

Then some people should save their pennies and move to a state where that isn't the case.
Then they should bother to pay the yearly doctor recommendation fee, so their as legal as can be.
Paying out a hundred something bucks a year to be able to grow and smoke legally is worth more then it's weight in gold.

What about big brother? I think cannabis is still schedule uno, or have I been in a hole?

I am not familiar the Apollo PAR reading, it's better to ask those cidly guys about that.

Here are some pictures about the PAR reading at 45W LED panel and 45x3W LED UFO at 12inch and 20inch, I got them from ebay last month.
The 45W panel is 137 umol at 12 inch, 106(105) umol at 20inch. Spectrum: 70x 660nm 0.5W, 42x460nm 0.5W. actual draw 38W.
The 45x3W UFO is 235 umol at 12 inch, but it dropped sharply at 20 inch,only 87 umol. Spectrum: 36x 660nm, 7x460nm, 1xIR, 1xUVC 400nm, actual draw 81W.
And the best PAR reading should be between 200-700 umol for bud. So both of these lamps are not good enough.

To be fair you got ebay el cheapo lights with no idea of the components they put in them.
The Apollos from all accounts on this forum seem to show strong results due to the use of higher grade leds and the such. Just wondering from people in the know if it will be enough for 1 plant @ 136W of the appollo 4.
TO be fair

An apollo 4 would be fine for one plant. The manufacturer does not have par readings (which sucks).. But neither does blackstar and the results speak for themselves? And the 130w apollo 4 (136w with fans) makes it the same as a blackstar 240,for less money, with actual 3w diodes, and a 3 year warranty.

I have been wanting to try a panel with whites and reds instead of reds and blues, seems a bit smarter. The manufacturer has different diodes you can choose from.

On a side note I am trying to see if they will sell me just the modules and drivers so that I can just wire them up without the rest of the metal around them. A 15 led cluster that puts out somewhere around 35w with the driver at the wall making heat instead of in the light.

It is hard to believe that they can offer a real 3 year warranty to an end user.
BTW, your white and red combination was what i thought in my next journal, i'd prefer 2700-3000K, for it includes blue-green-red spectrum.

Yeah i have been talking with them, love the customization option, they are so fast to reply as well its amazing.
Being a massive amateur at this. Should i include 1 white led per cluster?
Im thinking of going 7:1 Far red 630nm and blue 450nm?

Far red is 660nm+...

My configuration (per 15 led module) is:
5 630
6 660
1 nature white (6500-7500k)
2 460
1 430.

The next setup I'm going to try is:
4 warm white (2700-3200k)
2 or 3 cold white (12000-14000k)
1 or 2 nature white (see above)
4 660
3 630

My first spectrum I've got listed I've been using for almost a year now and it has been great. Produced some killer buds. I don't waste any power on uv in the panel and i just supplement it with the uv fluorescent lights, it makes a big difference with the panel cost and see little gain on resin production. And it came with a free sunburn too

I'll find out if that is true soon, I'm waiting to hear back from them right now about a few things and I wonder if that is still true. And if it is I guess I'm gonna have alot of reds.
