Cmh Vs Led O

[sixstring]

36 x 1.5
Plus misc odds n ends.

That' a hefty chunk of $

600.00 less on my power bill every month and yields up about 10-15% is also a hefty chunk haha.its all in how you look at things.up front cost,yes its expensive.but operating costs are forever :cool:

And dont forget you dont have to replace bulbs anymore like with cmh and hps.;)

So far havn't noticed any differences in the plants grown under the QB's. Seems like a good quality light that you can run a little closer than cobs. Makes sense for space limited folks.

I'm gonna order a couple and use them as side lighting with my cob up top.
Thank you

I went from about 900 to 600 when I made the cmh swap.

30,000hrs for the Philips 942 t9 bulb. At 18/6 is over 6yrs. 12/12 is over 5yrs.

But has light quality degraded at all?

I'm gonna go 4k I personally can't deny the buds they produce! I have no science behind this but to my eye they have way more frost

85% efficiency after 10k hrs.
Per Philips site. The bulbs are 74.00 a pop for the cdm elite 942 t9 (Philips best 4200k bulb)

I' running 4x4200k all thru flower and couldn' be happier. Started week 7 yesterday. The frost just keeps packing on.

Rad man, I'm stoked on that grow... need to go check in

I have an issue with my cheese. All others are fn loving the 4200k vs the 3200k. Next run gets 42/32/42/32 mixed.

I need to update that thread tonight.

I wanted to mix spectrums too but then I wondered... wouldn't those four be 3700k? Or cause the further away it might not receive ful light? But that's a question on its own

You would get overlap of K at the edges of the 2x K bulbs. The Centered plants should just the main bulb K.

Quality spectrum, no bulb changes, less heat, more yield/watt... Okay I've said enough.

get the cmh, marshydro is garbage.

I second Six's comment. All the peeps I know that have had mars units were not happy with them at all.
