Circulating Air

  1. When my lights go out after twelve hours. should my fan go off as well?

    or should i keep the air circulating while the lights are out?
  2. if you're able to, program the timer to turn the fan on every couple hours for about 30 minutes. Or you can just leave it on 24/7 like I do. You're not using co2, are you?
  3. no,no co2.

    my plants are 4weeks in 12/12 and are about 35-37" tall in 3gal. pots.
  4. run your fans 24/7
  5. if you don't their is a chance you will get mold
  6. coolcool.

    got it. thanks
