first time growing need help with lights

This Is my first time growing and I growin 10 plants how many lights/watts I need....thks bros

10 x 100 = 1000

No way to answer that.

10 plants 12/12 from seed probably 600W.

10 Plants vegged 12 weeks, possibly 3000W if you grow em big.

General rule of thumb is 100w a plant.
