I was wandering around and found this quote somewhere. Might be just opinion but I’m going to start another little STS clone and try a different spraying routine since my current one seems to be shooting blanks.
“ I will spray her once a day for 7 days.. Then again one final time after about 2 weeks. There are many ways to apply it. Its personal preference. But at mininum, once at the beginning and once again about 3 weeks later. The effects of STS blocking the signals to the plant only last for about 3 weeks. This is why some people get pollen sacs, with no pollen.. Because they only sprayed once at the beginning, or stopped spraying once they saw the pollen sacs. At least 2 applications are needed in a 3 week span for best results.”
