One will work. Minimum air exchange with outside of tent if not in a sealed room to get any benefits

Unless you are growing in a closed/sealed system, CO2 bags are largely a waste of money, as your fans will remove any CO2 before it has any chance of being of any benefit to your plants.

Fan vs Fanless LEDsHow effective are heatsink LEDs? I'm not sure if I should go with fanless (like Mars Hydro SP150) or with a fan (Mars Pro II Epistar 120). I struggle with heat, when the tent is closed it gets to 29-30 degrees with humidifier in full swing (HID lights) and I want to close it soonSetup. Lighting

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.Setup. Ventilation

Humidity Control TipsWhat is the best way to control night-time humidity? I have my lights-on conditions pretty fuckin' dialed in, but my lights-off time humidity is around 67-68%. My temps are great at lights-off, around 71-73F. I can put a big dehumidifier in, but I don't want to yet. Any thoughts?Week 2

Struggle too keep Plants healthyHey, I really struggle with the heat. In the night, when my light Mars Hydro FC-E4800 is running currently at slightly less then 25%. My tent already reaches temperatures of 29Celsius. Though to increase the strength of my activated carbon filter, decreases my humidity too muchLeaves. Curl down

Cardboard box method for dehumidifierHi 👋 can anyone tell me what success they’ve had using the cardboard box method for housing their dehumidifier? My unit is heating up inside the tent so much as it works harder during flower to keep humidity levels lower. Before I make the switch I wanted some opinions?Setup. Ventilation
