should i flower with both LED's?

Started my grow tent with a cheap galaxyhydro 600w led unit(actually did a decent job vegging) about 6 weeks ago but recently i got a optics 250 watt vero29 that im using for flowering, i started with 7 plants in my 4×4 grow tent but now into flowering i only got 2 females which sit directly under the vero29's, would it benefit me any to use my old galaxyhydro led or just strictly use the veros? Also at the moment i have the magnifing lens on will that give me better results?

Example of what i mean

If you have the cooling capacity and the electricity i think you should rotate your blurple light around the sides of your plant and observe if there are benefits.

I was thinking the same thing maybe bring the blurple down to the base of the plant see if it helps the lower leaves.

ya definitely worth a test. i grew super nice flowers with vero 29s but surprisingly the mars grown flowers were frostier.

As i have heard that the blurple light does give u frosty nuggs but u trade off the density of the nuggs.

ya density and potency too. i . added uvb this time in hopes of a potency boost. Although past flowers were very satisfactory.

Low density is mainly caused by LED sellers boasting that a crappy 300W LED with actual 200W dissipation replaces a 600W HPS resulting in a very low intensity IMO.

Hey Stoney!

I think the blue and red colors are mostly used from the younger leafs on the outer areas. So in my eyes place the blurple in the center and the whites to the sides if heat, consumption and costs are irrelevant.
Maybe slightly slanting the whites, if you want to illuminate the lower regions better or a bit more for more overlapping light cones and better mixing effect.

200 w dissipation with <30% maybe closer to 20% efficiency see platinum led

Do u mean slanting the whole led box?

30w/ft2 is what I see most COB LED growers shooting for. I would say the 250w vero 29's would do the trick. But as @testiclees pointed out you could use the other light for some side lighting if you wanted.

Yepp!
Just set the light cones by slanting the case 20-25° towards the plant.

Hell yeah!
Only 40-50PAR/w for a Platinium
But hey, if it did not goes on efficiency ...
...40-50PAR/w is a good punch at least in blue/red
And if it is been laying around, why not?
Will certainly deliver more revenue and perhaps better/more resins.

You might be surprised how ineffiecient some LEDs are

worse than that???

I'm not saying that platinum is the case but yes there are some with efficiency <20%. There's hardly a way to tell.
We have access to some datasheets of low end chips. But one has to realize that there are other things beside bad overall performance - bad packages, bad temp and current droop, bad thermal design, binning at 25°C, overdriving, cheap lenses/reflectors...this all adds up.

With other words: pity about time, money and materials!

So here's how i set it up i think i tilted more than u suggested but i think it should work, i put the led on top and have the optics vero29's pointing horizontally for side lighting, what do u think good or should i adjust something?

I think I personally would have done it the other way around, Used the vero as main top light and the other for side lighting.

Agreed!!

Save the amps, just use the Vero unit.
