We do come with white LED, buddy. Englishrick was growing with white and purple.
The Mars is a stronger light,, I think the lux meter showed this ,,,
I keep putting all the stuff I want to grow quickly under the Mars,,last week the little ones were dogs,, but now them little pots are the mac1 clones I'm planning on flowing in the next room when I move the Mars into a flower room,, ,,
the hgl light I find hasn't got the power and dark spots are allover,, fan leafs grow big under the hgl but nodal points are more in abundance on the Mars side,,,
I believe the hgl is best suited for finishing buds,, I do like the purple spectrum
The Mars grows Bush in hours
