It caused severe damage to a single floor commercial greenhouse and its contents, although no one was injured.
A Lincolnshire Police spokeswoman said: “At this stage, we are treating the fire as suspicious and fire investigators will be meeting with our officers and crime scene officers this morning to investigate further.”
