  1. whats best to grow autos under a maetal halide or hps?

  2. Well i dont know much about autos but i know that its best to use mh for vegging and hps for flowering but hps can be used for vegging also .
  3. iv been using metal haldies for 1 month and 3 weeks and its starting to get some nice buds on itt but im switching to 12/12 for all of them which i know i shouldnt do it but i had an auto out of the bunch of my photos i have vegging and there aall being switched soon
  4. I'd assume HPS, but I've never grown 'em, so my assumption is just an assumption.
  5. well id also use HPS , mh is good but HPS is beter :)
  6. Maybe try HPS plus some daylight CFLs for the first week or two, and then cut the daylight CFLs after that?

    That's probably how I'd go about it if I only had one ballast.
  7. Grew 2 last harvest. Good rule of thumb is HPS can be used seed to finish but MH shouldnt be.
