Ok got some pics. just one Fem?
It can vary. Im not really familiar with LED but 15w seems low.
to see a normal flowering cycle you need a bus load of CFL lights
or atleast a 250w HPS.
the thing is lights go by lumens , say a cfl is 100w but only uses like 43 w to work an led can be 15w but produce the same 100w of light we really need the lumens the light puts out to see how many true watts it really is
