HELP! Fans in the cold 🥶

[Melissinmass]

Good morning my green thumbs!

This is a follow up from my post yesterday. I have a grow going in a small low tunnel which is not in the best location. It gets direct sun mostly afternoon due to a tree that grew exponentially that we could not afford to trim or remove this year. I have three box fans and a few little clip on fans on 12h and off 12h that are used for air flow. There are 8 vent windows on the sides and one zip up door. I live in Mass and it’s going to get frosty ☃️ soon! Do I keep the fans going and close the windows and door to keep the circulation going or should I shut the fans off or turn down the amount of time to keep it as warm as possible in there? Should I put in a space heater(s)? Also they were on a soaker hose for 90min daily until A few days ago and I’m wondering if that should be less now that it’s not so hot. Anyone have suggestions for length of dripping and/or how many times per week? Many thanks 🙏 in advance. I’m sure these questions have been asked an answered but I appreciate your input!

we have the same problems in the same state I have a GH as well I have fans as well I shut them off at night but in Morning I light the propane heater 45,000 btus then turn fans on I leave the heater on until the sun hits them , I water by hand because weed likes to dry out then get soaked ,they tend to use less water this time of year so I would shut drip system off check with a meter and water when needed, my woods grow I give them 3 Large DD cups 2 weeks ago it was 4 cups .we go out every Monday and thursday/ Friday to check/water if they need it,

The GH was at 96%RH this morning ,so I lit the heater and turned fans on , I just went out and checked the RH is down to 61 it will go below 50% soon and the temp was 61 at canopy and 55 power down lower. if you can get any moister off the plants as soon in the morning as you can its the combination of cold and wet that causes BR to go crazy overnight ,so even though the rh is high in the morning it drops down by 9 or 10 so they are ok for the day its a juggling act really lol

I am in North Central Mass how about you
