Sorry to hear that bro my mom just had a hystorectomy last month to get rid of that shit
he took measurements on the inda gro during veg in his old thread when he was going by tags. I think it was 700 umole/s with pontoon at 18 inches.Chaz,
In the 'Measuring Plant Light' article, the chart for Yield PPF based on DIN 5031-10 sensitivity curve show the 420 w/pontoon at 431. This is about 20 Moles/day @ 13hrs. Do you know what the height that reading was at?
Does anyone know if someone has measured the PAR values of the 420 like Greengenes has with the AT600 at different heights?
Good question Loon! All five metrics of the technical comparisons are PPF measurements. If you check out page 11 of the VCF document it describes the differences between PPF (lamp output) and not PPFD (over a measured area) you'll see that these are all lamp output values not measured area values so distance from the lamp does not apply. Also there have been updates to that paper that begin on the middle of page 16 which I think you will find of interest.the 'Measuring Plant Light' article, the chart for Yield PPF based on DIN 5031-10 sensitivity curve show the 420 w/pontoon at 431.
