hello please could you tell me which is better for a 120 X 120 X 200 TENT with 5 inch RVK extractor fan & 5 inch RVK intake fan
Using an Evolution Digital Fan Speed Controller or GSE Controller Humidity, Temperature & Negative Pressure ,which controller do you recommend & why ,uk weather tent in bedroom, thank you intake from outside
I see that the GSE Humidity, Temperature & Negative Pressure Controller has the negative pressure setting but the evolution does not seem to have that setting but has an extra heater setting
but my heater has temp setting anyway,
So dont know enough about negative pressure to know if having that extra negative pressure setting over an extra heater setting is better or not.

Also would like to know if both are variac/voltage stepping controllers as to prevent fan buzz if anyone has used them

thanks
