I recieved my black strap with 6weeks left of flowering, the first treatment saw 20 to 30% increase in yield. I also used a brown sugar broth witch one of my local grow gurus says is terrific for bringing out the other canabinoids not just THC. I got a buzz almost narcotic with couch lock properties. Resiny joints and it keeps getting better in mason jars in my fridge. The flavors came out smell is divine but yeild of my indoor white rhinos is the only disapointment, i used bud candy for my indoor but think it is just too hard to keep these crazy indoor strains consistent. I had one mother I kept for clones but still she could have been better....Blackstrap 14.99 and bud candy 42.00 bucks. Too muck hype on some of these products. I dont know if im smoking advanced nutrients or THC. Will try again in 72 days.
