I used it on some F-13's a week before flower and then once a week for the first 3-4 weeks. Stopped pollen sac formation in veg and never saw another sac. The person who told me about it says that it is a must for their garden as they grow mainly landraces that have a higher herm ratio.
To me, it's one of those "I'm glad I have it, but hope I never have to use it" kind of thing. |
