Hello 420 growers, ViparSpectra would like to take a survey with you for helping light design, which may take a few minutes.

Q: Do you calculate PPFD (umol/s/m2) to DLI (mol) when using a light?

What's your answer? And why? Thank you.

* Daily Light Integral (DLI) is the total amount of photosynthetic active radiation (PAR) in a day. The total amount of light the plants get in a day should be more important than how intense the light is. For marijuana, the sweet spot is 43.2 DLI. The formula can be easy:
PPFD (umol/s/m2) x Time (s)x 0.000 001 mol = DLI (mol)

Hence you can go to the manufacturer's PPFD map and pull as best you can from the results.
 
no. will reference it but it's nothing i follow. i watch the plants and react to them. i also have a tendency to over light.


i move away from things that add more gear, or more complicated gear, into the equation. i only add gear and change techniques if i need a solution to a problem.
 
No, never taken any notice whatsoever
Plants are the best light meter, humidity meter and just about everything else
What I don't measure doesn't bother me

Thank you for your feedback! We should indeed listen to the plant's response when planting and make corresponding adjustments.

Yes, everyone has their own exclusive way of growing, and the most important thing is that we can use the equipment well and grow better.
