My son has a growing facility right next door to his home.
Unfortunately he has to leave a lot of the time to meet with various customers and other growers in the marijuana industry.
Due to this, his grow op is left totally vacant. Now a lot of things in the growing room are taken care of. My son has a complex HVAC system with timed programs. He also has lights on a 12 hour brightness and 12 hour darkness stage. He even uses a humidifier and a dehumidifier depending on the time of year. All of this is monitored via an app on his phone. Thankfully when he leaves, I don’t need to touch anything. Typically I just check over his house, flush toilets, turn lights on and make sure nobody has messed with the growing operation. The issue is that there are different stages of growing marijuana. If my son is in the budding stage, I never have to do anything. I know he doesn’t leave during marijuana harvesting. The issue is when the weed is in the curing stage. Curing is simply when the pot is separated into glass jars almost full. If he leaves during curing, I have a few jobs in the growing room. I have to open up the jars to let moisture and humidity out. If the product feels moist though, that means they did not dry properly in harvest. So then I have to leave the jar open and check back every hour until they are. The moisture likes to work itself out of the jar. It sort of reminds me of when I make sauerkraut.
