color temp is just one measurement and there are an infinite number of spectra that can create a given color temp look at spectra of full sunlight, ~5500k http://www.crslight.com/images/sun.jpg look at spectra of a 5700K LED... its nothing at all like that...

just a heads up that 3000K in an HPS, 3000K in LED, 3000K in fluorescent, and 3000K in CMH are all completely different spectra. color temp is a very very simplified way of describing the quality of light

see thread above they are generally of dubious efficiency and reliability and force people to have hot 110VAC leads all over a less-than-ideal environment for them

all the recs are on point high voltage series is the only game in town with the 68V vero Cs and as mentioned you are at the mercy of (slightly) lower efficiency drivers as the 600W drivers arent available in high voltage. i think the rating on the veros is right around 400V (@welight ?)

what were the numbers?

link your "1000W" light and we'll try to advise on what it will actually be able to cover. no reason to veg more than you'll be able to flower

the newer apogees with the flatter response are a good intermediate between the hydrofarm and the licor

best thing under $300 https://www.hydrofarm.com/p/LGBQM

most par meters measure par range only if you want accurate readings of IR and UV as well you'll prob be in the thousands

I NEVER NOTICED SPIDER DICK WAS ROCKING HOTPANTS

depends on the efficiency of the light but 200W in a 2x2 (50W/SF) should be over 1100 umol if all the light is hitting the canopy with a 50% system efficient light

there arent you need to get the non-SEs

check out my new "hydro carts" lol only $299.99! https://www.amazon.com/WEN-73002-500-Pound-Capacity-Service/dp/B00H1V4EB2

agreed. you can grow GREAT weed without supplementation and unless you are growing consistently great weed you risk overcomplicating things and reducing your overall quality and yield.

my theory: people here know the difference between a decent LED and christmas lights and are tired of dozens of people justifying their christmas lights by demonstrating that they can grow a plant, with no other metrics or useful info to be gained.

in conjunction. google "Emerson Effect" ive also read about some limitations of that approach here, cant remember exactly...

not sure if greengenes youtubes are still up but that was some great COB porn as well

well not sure if 3 year old threads are all that worthwhile. even mars is several generations beyond that
