You only need to spray ONE branch..... A single branch will produce more than enough for the whole plant. you don't need alot of pollen at all.
Look into Colloidal Silver. You can get a 4oz bottle on amazon for $20 and it will last you many many times over the TM. you need an entire bottle, sometimes 2 just to get the plant to self.
So try it for yourself and let me know if that is accurate information on the product or not.
I got a 4fl. oz. bottle 500PPM for $20 diluted myself and have a TDS-1 tester.
