Yes! check on the internodes for banana shaped pollen sacks! suck these off with a hoover.. attach a long thin pipe down the hoover then place the end of the pipe next to any bananas. This a bitch of a job as they keep growing back. You also might want to mist lightly before doing this to ground any pollen in the air. If you dont do this theres a strong change your whole grow will end up seeded.
