need some advice... the hum is very low in tent...around 30%... i have not set up the extractor fan ... should i set it up....?
put the propagator lid back on but lift one corners an inch
this will raise the humidity.
if the temps are good you don't need an extractor fan or intake fan for the next 3-4 weeks
extractor fan/filter are there to stop the smell, keep the humidity low and supply the plants with fresh air
at this stage your humidity low, plants don't really smell till there 4-6" high
there no canopy so you don't need fresh air, just open the tent twice a day will do the job
