MH and HPS bulbs during flower
Digital versus high pressure sodium
March 24, 2012

I know that I need to change my bulbs when i am switching to flower to HPS but i cant afford them right now. How much would my yield decrease by keeping mh lights all through flower? ANything else i should do different have had 6 grows but always used hps at flower and want to know what could go wrong with my garden.

  1. Try to use mercury halide (MH) bulbs to get bigger yield, 25% or more yield, if at all possible. You will wish you would had, since mh bulbs give blue spectrum the plants need. Always use mh for vegging and hps for flower.
