    PPFD Graphs and Analysis

Since then, I've also measured the Mars Reflector 192, Philips CMH 315w, etc. The point of this research is to determine the optimal footprint and...

    Par question

    How many pars does it take to grow one plant. Lets say for instance that I put my light 1m above the canopy and the par meter tells me 83 par. And the lower to the floor lets par and closer to the light the more par I get. So how many pars would it take to flower one plant?

    PAR bulbs and Lumens question...

    Hi, I have been looking at some lights and am getting confused... Is a PAR38 light (90W) with 1200 lumens better than a regular 100W 1600 lumens bulb? I understand that the PAR light can be more concentrated and directed but which one is actually better to use? Thanks.
