Hey guys and girls

Which would produce more ?

I already have 600 watts of cobs

I want to spend my money wisely and any in sight would be great.

600watts of cobs beat the ass off a 600hps

Now I have more capital to play with I'm looking to up my yeilder and quality

I can pull a kg off 600wats of cobs and 600 hps in my set up

I'll probably add another to auto pots to bring me to ten

The QBs will produce more but just slightly. With the huge difference in price I would go cmhs. On a side note that mutch light would bennifit from co2 enrichment. I would get cmhs and with the money saved get a co2 system

600 watts of clu048 citizens a mix of 3000k and 3500k
And a 600hps budget it bulb and digital ballast in a 2x2 meter area I will be adding reflective stuff on the walls, ceiling and floor next run

Nah proper qb with Samsung chip. I did blurples and they sucked floppy donkey dick. Not bad as adding to spectrum but not a main light

2 SS 315 watt cmh lights, 2 plants, gave me a finished weight of 26oz, from seed, in about 100 days.. 1 light over each plant in a 24"x32" scrog screen.. 315 watt CMH are only a few percent less efficient than the same wattage of the better leds. i can link to the post of the plants in a cmh thread if you want....

I can chime in and say that 2 SunSystem LEC'S really did me right. They also used next to nothing on my power bill. I ran the 240v versions.
