Well, some people say to get a paint brush (like in kids watercolor) or Q tip and just kinda work it around a little touching each flower.
I had success just using a fan and flicking them with my fingers. In the afternoon, the sun shining in from the south west makes the room pretty warm so I always turn on the fan. Then as I go by the plants, I give them a little flick with my index finger and thumb. So far it has worked ok.
Ok, but what do you flick?
I told you I’m not real good at this...
