Yes, that was Flower dragon. Thanks for reminding me… I remember maybe 2 other bottles that were available just as limited samples and never got proper license for selling in EU commercially. It was said that due to chemical contents… Hard to guess. Was it really PGR (plant growth regulator)? Can’t remember…
But Flower Dragon was reported as working, so some growers were pretty sad this didn’t make it to market… But I agree that I wouldn’t treat plant with anything that I can’t use on food crops.
