Hey guys, tried to find a thread about LUX and auto flowers, couldn’t find any, so I started the thread.

Just wondering if the amount of LUX needed for autos are the same as photos?

As what I currently know for photos,

  • Clones and seedlings: 5,000–7,000 lux
  • Vegetative growth: 15,000–50,000 lux
  • Flowering: 45,000–65,000 lux
  • Maximum recommended amount of light: 75,000 lux

In the past few years ppfd has entered into the mainstream as a term that all growers should be familiar with. There's tons of write ups online about optimal ppfd levels, so I'll spare you all with repeating it here. More recently, and with less attention, the topic of DLI has been discussed in...

75000 max? Are you sure that would be about 800 umol for 12 hours or am I way off?

When taking readings with a basic LUX meter on full spectrum LED ( SP2000 for example ) - I've read that the reading is not true because some of some of the spectrums not seen, PAR meter yes.
So the question is what percent should be added to the measurement on the LUX meter for a more accurate number?
