 Nope no co2

Running about 800ppfd at 12"
Temps 81 humidity 60

Thx
With no CO2 why run over 500? We determined long ago with HID with high light levels you must add CO2. http://fluence.science/wp-content/uploa ... .27.16.pdf

Last 3 grows were ~950ppfd , i dunno man, i just watch the plants and take them to max until they stress then back off. All full runs no hermies. I'm using a cheap lux meter to measure intensity so theres that too :D i do want co2 , i'm getting there, it's taken me a year to get this light this far lol

Not sure who “we” is, but that doc says start co2 @ 800 ppfd for flowering. His ppfd is fine....

Aloha & in the 1970 and 1980 eras PL lighting was state of the art. They showed us to be up to Dutch standards production wise using their lighting you must add CO2. I had the honor of talking to Mr. Poot in Seattle in the 1980s. http://pllight.com

Now that i’ve got a flowering plant, i shutdown two of the four incandescents in the growroom; and changed out the other two to these:
