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 enough light at this phase (still waiting for them to root)? And what is the optimum amount of light the bigger plants
should be getting?

Oh yeh i currently have a 1000w and 400w lights up but the clone box is about 5ft away from the these light sources. thankyou. :rasta:
