Ventilation on schedule?
HomeGrown_Medicinalstarted grow question 3 years ago
If I put my ventilation on an hour on/hour off schedule to raise the RH (RH when cold is around 30%) and help relieve my heaters a little, will it be detrimental to the environment?
I've got heaters on controller,
Temp is steady with ventilation on but wil be expensive in winter

As long as you have a fan inside the tent for air movement during the off period it should be fine but once you flip to flower I would keep the ventilation on to help prevent stale air from sticking around your buds and causing moisture issues. If you don't have a humidifier though I would really suggest getting one. Particularly one with a humistat that will turn off at a ceiling RH.

Ventilation set upI just got my first grow tent- a Vivosun 32x32x64 and a Vivosun 4” fan and carbon filter combo. It came with directions for the tent- but nothing on the ventilation system. What’s best as far as set up? Any tips, recommendations, or photos.? Does it need to vent outside?Setup. Ventilation

Won't Oscillate AnymoreI was wondering what type of oscillating fans that everyone uses in small grow tents. I have been using the Vivosun fans and since they won't last I'm looking for alternatives. In case it matters I'm growing in a 27x27x63 MarsHydro tent.
