I got 8 ounces of bud plus 3 ounces of good trim for cooking off my last grow which I think was 63 days in total if I recall correctly so worked out to be $322.3760904 in electricity all up. so about $40 per ounce. Ounces here go from anywhere from $300-400each, usually around $400 though for average quality so it was definitely worth it for me, hoping to only improve my harvests more
