It's a good idea to thoroughly clean & disinfect your grow room after each and every operation. Along with lingering pollen, you also have to worry about mold, pests, and other unsanitary conditions that could potentially infect/attack your next crop.

Just remember that old clichéd, but relevant, adage:

"An ounce of prevention is worth a pound of cure."
Mr. Clandestine Reviewed by Mr. Clandestine on . Pollen in growroom Will pollen from herms linger in your growroom and cause future plants to seed? (when i say future i mean like 3 weeks to a month)... how long until pollen is no longer viable? Thanks! Rating: 5
