If I put 1 of my plants into flower strating with a 600 metal halide for 1 month then change it over for the rest of the time to 600. Hps what would it do? Would it hurt it?
The MH for the first 3 to 4 weeks of flowering cycle will help control the stretch (really stretchy Sativas or Sativa doms) and supposedly for the last 10 days of flowering the MH makes buds frostier...idk about that personally tho
