So what's an average yield/plant for an DWC auto under 4x 3500K? People seem to be surprised and disbelieving my yields on my first grow. I got 9.1oz from my White Widow and 15.75oz from my Blueberry. I've only grown the 2 plants - is this normal? Can I expect 1/2 to 1lb/plant consistently?

DWC can produce huge autos that yield huge.
I've got an Autoseeds SuckerPunch right now that is taking up half of a 3 x 3 ft tent, but wants it all, and I've had to tie it back.
Even after topping and training it's over 5 ft tall, and getting too close to lights.
If it had all the elbow room it wanted, it would probably yield over a pound dry.
At the other extreme a Mephisto StrawberryNuggets is only 2 ft tall, wider than it is tall, and will probably only yield a couple oz.

This all depends on strain and breeder.

Would I lose or gain much if I swapped-in two 6500K AutoCOBs for two Amare 150CR units, with these currently used up high to supplement 8 x 55W 5500K AutoCOBs in a 12.5 sq. ft tent (740 watts draw; ave. 59 watts/sq. ft.; generally 8 plants in the tent) for the plants at one end of the tent in bloom. The Amare units are very respectable LED units, using all Cree LEDs, a lot of them white (full spectrum) and red, but they have fans (tent is right behind me in my offce/rec. room; less noise the better) and together draw 300 watts. Two 6500K AutoCOBs hopefully will at least comparably supplement the base AutoCOBs during bloom while only drawing 120 watts (saving 180 watts and related heat).

In terms of plant quality, potency, etc., would doing this be an upgrade, downgrade or neutral? I currently get consistent very good results growing in 3 and 4 gallon Air-Pots, coco/perlite, using MegaCrop base nutes. My main interest is reducing power, heat and noise, not trying to solve any plants- or lighting-related problem.

Have you considered just turning of the Amare and running only the 8 COBs now without adding anything. You might have enough light for your needs already

8 cobs in a 3x4?
seems like overkill already. holy cow .light stress and foxtailing may be an issue..not even counting the other lights

I love the 6500k ive got 2 covering 4 plants almost and the trichome production will double under that spec.

under the 6500k? upgrading next fall...might have to try a couple..!

Yes I have 6500k and 3500k in my room.

ive got the 3500s and 3ks..and pretty good results..always room for improvement tho..

I've been running different spectrums for a couple years now and one thing that had stood true is that the higher Kelvin the tighter and frostier the bud. I've run enough at home tests to stand behind what I've said.

How do you use them? 3000K early flower and finish with 6500K? Or bursts of 6500K on 3000K? Or dim one but push another harder for different ratios?
