Minimum temperature

  1. I've recently set up a 4ft x 4ft x2ft grow box in my attic / loft. The lighting is a 250w hps. When the light is on the box is warm but during the night when the lamp is off it gets pretty cold. Will my plants be ok?
  2. Ave,

    Ideal temp Is is around 75deg. F But for sure dont let the temp drop below 40-45, i think your only supposed to drop the temp about 10 degrees during the night cycle, colder than this will probably slow growth significantly.

    Take care.
  3. Ave.

    I am curious, did you construct your grow box only 2 feet high? If so, a higher space is reccomended... once your plants go into flowering they may grow like wildfire. ok perhaps thats a bit of an exaggeration, but its likely you will run out of height.

    Take care.

  4. No it's 4 feet tall x 4 feet long x 2 feet wide. sorry.

  5. That's still going to be cramped in height once you factor in the size of you grow container. Check out a scrog method to help squish your plant into your grow space.
  6. Already have mate!
