Running MH 1-2 weeks into 12/12

  1. Just wondering if anyone has tired this. Since there is no flower growth till the second week or so, I was thinking to running the 600W SolarMax conversion for the first or maybe second week of 12/12.

    This should keep the flower nodes close as they fist come out?
  2. To go into flowering mode, the plant undergoes hormonal changes that are triggered by both the increasing length of dark period and the spectrum of the light. If you want to start flowering when you switch to 12/12 (and why else would you switch) then switch you light to HPS at that time as well.
  3. agreed

    if youre worried about stretching, or if its an issue, just add some 6500k cfls to your HPS. gives you spectral depth, and added light, both will help with the stretch
