my 1000W HPs light puts out 150,000k lumen i read that 90,000 is too much light, it is not good for the plant so im wondering if this is true? thanks

i dont know if its true or not, but i have grown a seed under 1k hps light before and it turned out fine. Remember that the sun has alot more lumen then 1k does and if a seedling can grow just fine outdoor then it should be fine with indoor lighting.

The amout of light/lum that the sytem put out is mess. in an area of space. The amount will disapate the higher the light is from the plant.

Hey,
Here is some more info:
The minimum amount of light required by marijuana plants is around 3000 lumens per square foot. However, it's not 100% accurate, since although you may have a 10,000 lumen light, the amount of light that reaches the plant varies with the distance between the light and plants, and reflectivity of the grow box. The ideal amount is somewhere around 7000-10,000 lumens/sqft, and as long as the plants do not burn, as much light can be used as you want.
(*note, the sun produces about 10,000 lumens/sqft, on a sunny summer day).

Can any one confirm this... ??

Or possibly explain how this information was gathered... ??

Anyone have a light meter and want to test the theory out... ??
