so got my scale back and have checked the yield of my two plants grown under the two 48x5 reflectors that arraived 14 days into my bloom cycle.
the small white widow after ten days drying was 51g plus a bit of sugarleaf trimmings and few popcorn buds
The unknown rqs strain was 103g after 14 days of drying plus 5g popcorn buds and a bunch of sugarlead trimmings
my old light that was 90w ufo + 2x20w sidelights floodlight IP65 type of lighting. Those yielded about 80g in my last grow. using 130w
my new mars light running at 220v should use around 90-100 (i think closer to 90) watt each so 180-200w total. So taking into consideration the new lights being installed some weeks into bloom and battling a spider mite infestation up till week six of flower. im pretty satisfied with the first grow with mars. i hope to make use of a bit more horisontal space in my next grow so hopefully that will up my yield a bit further.
im so glad i finally found the money in my tight budget to make this relative cheap upgrade of ligths i must say.
