Question by Edward F: Ventilation and light times in a grow box for cannabis?
I’m a first timer to growing cannabis indoors and in a grow box, for entirely botanical purposes of course. The size is very small, 18″ x 6″ x 18″. I have fans installed in nice places, I just need to know how long to keep the box ventilated if it’s not at all times. Lighting information would also be helpful. Thanks!

set up a timer for your lighting, fluorescent is best, on warm white bulb and one cool white, 14-16 hours a day, put the fans on the same timer, now you need to keep it about 80 in there all the time, i made my own thermostat contraption.

If your cannabis plant is 12 hours light per day is likely to mature in 2 to 2.5 months. If you have 16 hours of daylight, they will probably be blooming in 3.5 to 4 weeks. With 18 hours of light per day, will flower in 4.5 to 5 months. It’s a good idea to put lights on a timer to ensure that the amount of light received each day remains constant.
Hello
Yeah thats a very small box, so you must be using fluorescents as grow light, make sure you use cool blue-kelvin about 6500 for veg, then worm white-kelvin 3500, should give you this info one one of the ends of the bulb, only need to vent while the lights are on, also keep temp to 72-85 f.
Hope this helps;)
