@K4TZ3, It's even more effective to spray the oil (emulsion that you need to dilute 1:100, here: https://amzn.eu/d/9vETA9r) directly on the leaves (including the undersides). And when watering, use SF nematodes if you have fungus gnats; those pesky little flies...). You can also find them cheap on Amazon: https://amzn.eu/d/08GGvvQ
@Patricia_Zamnesia, thanks ... I'm already looking forward to this strain. You hear & read a lot of good things about Blueberry, it seems to be very well-known & popular. 😎
