lumens are the measure of light according to the human eye.. not the plant, so you can't go based on that.. i dun understand how u can say they ahve no business with workin mary j, when they've worked on numerous plants.. they deliver more of the spectrum... i HOPE u read the other LED threads, we've been researchin this for a minute..


this is all experimental.. its been proven to work on other plants, and they're using it in space.. that SHOULD be proof enough that they should work on a mary, its not a mutant ninja turtle, its a plant..
