  1. i have 12 seeds in plastic cups. 6 sprouted the other day. how big should they be when i putem under the mh light?
  2. You can put them under the MH as soon as they pop through the soil.
  3. Veg with MH as soon sas they pop through the soil. Just make sure they are not so close to the light that the heat kills them.
    Get an HPS conversion bulb for flowering.

  4. yeah roger that ... the heat from that lamp is the only thing the seedling wont like ...be careful:wave:
  5. If you have any flurecnts, I'd start with those till they get some height to them. Sometimes using a high intensity light right away will kill them. If thats all you got then you can use it tho and it will work fine.
