4 autoflowering plants (2 Magnum XXL Auto, 2 Disel Auto) with a 315 watts LEC in a 4x4 Grow Tent. Magnum XXL Auto is a strain by a local seeds Bank called Ecuaseeds.
@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
