How long should I leave my air pump on?
Chow_13answered grow question 4y ago
Depends on your setup. What are you running? With my rdwc system I keep the air pump on 24h. The more oxygen in the water the less chance for root rot.

Hello. Its good to saturate your water with oxygen once a day first thing in the morning. I would leave it on for 15 to 30 minutes. Chuck.

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

Can't vent exhaust fan outside, is this a problem?I have my 2x2x4 tent in a closet, with a 4" carbon filter inside the tent and a 4" inline fan outside of the tent, exhausting. But I have no way of directing the air to outside or even out of the room. Will this be a major problem for me? Room is otherwise AC'd via central air.Setup. Ventilation

High RH in flowerI find it really hard to keep the RH below 50%, especially at night when temps are low. I have a dehumidifier in the room where my tent is in but even when it's below 50% there, it still is above 50% in the tent itself. Can somebody explain this? Probably help me with a solutionWeek 14

Help with airflow. I've got an extractor and 3 circulating fans. Would a powerful inline fan be better than the 3 circulating fansQuestion about environment here.
I've got a 5x5 tent. Total 46m area.
460m3/hr needed to be extracted.
Extractor fan is capable of taking 600m3/hr.
I did have in an inline fan but it's no longer working. Do I need another inline fan ?? I've opened two ports for passive intakeSetup. Ventilation

New Light? Find a way to raise light? More Fans? Combination? (Light: 44" above ground level | Tent Height: 63" Day avg: 78.6f) Should i worry?What do you guys recommend as far as lighting for this tent? I have a 300w led light but at the height it's currently at it is producing a large amount of heat with my exhaust and two oscillating fans? I also have other plants in with my seedling so could the humidity cause it?6y ago

High humidity in the morningI’m having a very hard time coping with humidity (goes up to 85%), since I physically cannot get the airflow outside my house for various reasons. I open the window each morning, but could it lead to rottening in the late stages of flowering? Thanks for your replies ;)Week 9
