She is growing super fast with the 315 watts LEC, only see the diference between day 20 and day 21. Replace Bio root with Flora Blend, very happy so dar.
@RootsandBudsGrow, Ive heard nothing but great thing with CMH but never have grown using this type of light. As for 24hrs with autos Ive ever tried either. So fare every autos Ive grown ive went with what the plant tells me and when I see the fan leaves going down before lights out that uaually a sign they need some hours of rest/darkness so the max Ive done myself is 19-5 in flower
