Is this even possible? 650w Meijiu Bar Light. 3.0 umol/J. LM301H and Osram. 1950 PPFD!!!!

Emotional day, it seems. So much for weed chilling people out, eh?

Maybe y'all need some melatonin and a nap.

Stay humble kids. When you drink too much of your own kool aid. this is what happens.

Got 2 quantum boards 240 watt 3500k+660nm. 3.2umol/j. Fried my tops

I’m chill. Until dipshits try to muddy the water under the guise of “questions”.

Have a nice day.

When people can’t read the title of a thread this happens.

 

[DrKiz]

Just curious what was your experience with majo? How’d it yield for you?

Excellent lights. No complaints at all.

 

[end_of_the_tunnel]

No, they are one of the few who are not lying about their products, and they have sphere date to back up their claims. Science doesn't lie. And BTW, they paid the $1000 fee to have chilled's light tested.

Inflated figures you spouting mr gro..ft.pop22. $800 for test. Oh the righteous indignation. Fudging figures. How can anyone make a mistake? So funny.

I have no clue about what the best led brand or fixture is.
But the fact that strips provide a better spread of light and better penetration is just physics.
It is not an opinion, it is a fact.

 

[hillbill]

Natural processes at work here as the board/strip tech is widely adopted and diversity of forms lessens. Imitation becomes more rampant. At the same time the cost to produce quality lights has been falling, the efficiency gap has dropped dramatically between top tier lights and budget alternatives.
Another facet o& the present market competition is the simplicity OG building lights with no soldering and very few connections and freedom from assembling panels with discrete diodes of the past, and makes DIY possible for thousands.
Lots of competition and copycats and DIYers are just part of the landscape now, but whatever, many alternatives exist today that are very efficient and far better than old HPS could ever be.

MJ-650 rocking it. 16 days since flip.



Majo 800’s rolling multistrain 54 days since flip. Starting harvest on the Red Mandarine tonight:

 

[Keesje]

Could you not lower the light a bit more?

Not sure what you mean?

Better pic of the MJ-650?

As for the Majo’s, they’re dimmed. I can’t raise em anymore.

 

[Keesje]

I meant move the Majo 800 light closer to the canopy.

Very interested in your lights and also in your yield eventually!

Yes I can, but I’ve found with the bar lights there is a sweet spot for distance to produce the most even lit canopy.

Too close and you have weak spots between bars and hot spots under bars. Kinda.

BK-78 has some good numbers:


As for yield. I stopped weighing long ago. It’s personal and I compost excess. Easy pound per tray without effort let’s just say.

Oh, and at the end of flower... dimming.. letting them finish. A couple got a little light stress towards the end.

Always learning.

Looking at the 800s to replace my se hps.

Looking at the 800s to replace my se hps.

I had them custom made with 10 bars@800 watts. Normally the Majo’s top out at 9 bars@ 1000 watts.

If I can pull 2 per light I’ll be happy. Would like to get the gavita 1700e but price is up there

I know a guy personally who pulls at least 2.5 a light with the Gavita 1700e in coco. Ive seen multiple ppl on these forums and other sites claiming to hit 3+ per light with Gavita Leds or LEDs that put around as much light as it.

Im going for 3 with these Meijiu 650s I ordered. Ill have a few test runs with it in a 4x8 and see how the yield and quality fair against 1kw DE HPS in a side by side.

 

[Onymous21]

Looking at the 1000w octopus. Not worried bout electric cost so much as I am production. I have a few patients I grow for and just want to be able to keep up with their demands

 

[Gwhiliker]

whats the appropriate coverage for one of these 650... i was gonna order a few 720w bava quantum boards for around the same price but after reading about these im starting to change my mind..

You’ll be able to light up a 5 x 5.
