If you’re asking whether the viral “1 cup makes a peace lily bloom like crazy” trick is legitimate: there’s no magic one-cup ingredient that reliably forces a peace lily to flower.
For Peace lily, the biggest factors are:
Bright, indirect light — too little light can prevent flowering.

So if the “one cup” is rice water, coffee, milk, sugar water, or another kitchen mixture, I wouldn’t automatically pour it into the pot. Homemade mixtures can introduce excess salts or nutrients without reliably improving flowering.
Best simple approach: move a non-flowering peace lily to a bright spot with filtered/indirect light, water appropriately, and use a diluted balanced houseplant fertilizer according to its label during the growing season.
