So I just wanted to post this because a few days ago I spoke to both QSC and the board about how my recent growth kits were coming up cloudy after I mixed them. I was using BA water like I always do and after mixing they’d come up cloudy. So after doing some reading and seeing what other people use to mix the gh I heard some say sterile water, sodium chloride, and bA water. So I decided to pick up both a bottle of sterile water and sodium chloride water from the hospital and don’t own little experiment. I mixed just one vial with the sterile water and BOOM it turned out clear as day and everything mixed together smoothly and drew up perfectly. The only thing ither thing I did do different was after mixing the sterile water I just let the vial sit and slowly let the gh absorb and mix by itself. So I’m happy to say problem fixed. These weren’t the newest QSC 15iu kits, they were the batch just before those ones were made. I believe on the box the date says September or October. I can’t remeber off the top of my head cause there not in front of me.
