Wow, I don't know what all those numbers and big words mean, but I can tell you this, freshly cut clones awaiting roots, don't need a lot of light. Too intense of a light, will burn and wilt them.

My buddy cuts 20 clones at a time, and as they are rooting, he puts all 20 of them under only 40W of floro. lighting.

Don't know if this answers your question, but clones do not need a lot of light while rooting.

Question about light and PAR readings Hey i have a quantum meter that measures light, photosynthetic photon flux, in (micromoles of photons per square meter second) µmol m-² s-¹. The manual with the device says that full natural sun light should have a reading of 2000 µmol m-² s-¹. I took a few readings on the canopy of my room which varied between 350 and 410 µmol m-² s-¹. While my clone box at the back of the room is only getting between 50 - 80 µmol m-² s-¹ of light. My qestion is, are the clones getting Rating: 5
