Proiphys amboinensis flowers continously from November till February

It didn't rain at all in March this year 2019 in Thiruvananthapuram unlike the same time last year. The days and nights have been much hotter too this year. Yet the lily with the luminescent flowers Proiphys amboinensis flowered throughout January and February this year unlike last year. The flowering which began with the November rains in 2018 continued till February this year. The fragrance and the luminosity of the flowers remained the same throughout the flowering period from November till February.

With the shortage of water this year, rice water which is the left over from the cooking of rice was used for watering the plants. Could it have been the rice water which caused this continuous flowering?
