ppfd

Hi RIU! I'm new here and was hoping some of you LED experts might help me with something. I was watching a YouTube vid ( ) by Growmau5 (great LED YouTuber btw as I'm sure you all know) on the Vero 29 COB's and how efficient they are in Micromoles/per Watt and how you can use this to calculate...

This is a duplicate thread... please delete sorry for the double post. Hi RIU! I'm new here and was hoping some of you LED experts might help me with something. I was watching a YouTube vid (

Hello Rollitup, this is my first post. I've been growing fora while under a 600W HPS in a 4x4. I've just gone another summer with heat problems and I am looking at LED as a solution. Budmaster are local to me but I am struggling to understand their specs. It seems to me if the output of the...

going with a cob diy build frim what i seen 16" from canopy to light seems good but i def want some numbers/data to back it amd tips would be great

In the spirit of all this DIY cob stuff I apparently fell into, I became curious what else I could do. Google to the rescue. I found this gem of a post on another forum (non growing forum) by a poster named Hoppy. Take a gander and let me know what you think. I ordered the lux meter and...

I would like for everyone growing indoor to post their experiences so we can share and all try to get better results (if possible). Lets first try go get some even ground, lumens - are kind of useless but most of us have only lux meters to see light intensity. There is a number that Philips...

First off of like to thank Victor from Amare Tech. For making this possible & for always providing the best customer service & care possible. About to start mapping. I said I'd do it live so here we go. Setting up now. The Apogee MQ-500 is the Par-Meter being used. First light will be the Pro-9...

Hello, First let me say a huge thank you to everyone who posts here for the wealth of valuable information they share. You guys and gals have an awesome community. I specifically want to thank @SupraSPL and @alesh, as their previous posts have provided me with tons of useful information...

I've been a lurker on RIU for a few months, soaking up as much information as I can. During this time frame I've built multiple grow concepts, re-built them, and now have one completed harvest under my belt. I'd like to thank the members of the forum for their contributions to my success...

Hey, Y'all. If this has already been covered please just let me know, but I have been searching and haven't found any threads that really cover this. I want to get some suggestions for a good quantum meter. I have come to realize that measuring PPFD is going to be vital to tuning in my grow and...

I know the PPFD formula which is Input power [W] x efficiency [dimensionless quantity] = radiant power [W] luminous flux [lm] / LER (luminous efficiency of radiation) [lm/W] = radiant power [W] radiant power [w] x QER (quantum efficiency of radiation) [µmol/J] = photon flux [µmol/s] photon flux...

clarify some things for me please. First things first, I'd like to thank you all for the knowledge that is being passed around. I've lurked on these forums for years, and LEDs finally got me to ask some questions. My goal is to increase electrical efficiency WITHOUT sacrificing flower quality...
