Welcome to Riddleme's Tomato Garden, yes that is right I have some tomato's growing out in my back yard (had to do something with that bag of FFOF I had).
If you have read my threads then you know I am constantly telling folks to learn to better understand thier lights and that lights are simply one part of all the required elements of our gardens. Lights seem to be one of the most misunderstood parts and most folks pay more attention to the lights then the other elements (which is a big mistake). Also most folks believe that more light is better and that cramming light up the plants ass will result in better yields??? None of which is true
I have also said many times that a light meter is a must in this understanding process, the one I have only cost $29.95 and can be purchased here,,,,,

No it is not the best but it works and only has a 2% error margin, best part it is affordable for most everyone as $29 is not that much, but since most of you do not have one I thought I would share some perspective readings so you can see why you want one.
In order to better understand a few things it is best to take some readings outdoors of the good old sun so that we can get an actual idea of what is going on with mother nature. We all know that the sun is the #1 best light there is and that MJ grown outdoors is the bomb because of it.
for each set of pic's I will include a pic of the sky, the meter, and the canopy so you can see where thesensor is (actually is in the same place each time)
Here we go first set is under complete overcast, cloudy with no sun
Next same day as the sun breaks thru the clouds
Next a nice bright sunshinny day
and finally a sunset
Now I know that the forum retoric is to say that the sun puts out 10,000 lumens but as I have also repeated several times that is only at noon at the equator, as you can clearly see from my pics the best I got here in Colorado was 7200 lumens.
Anybody seeing the light yet???
