Hello THCfarmer community! Im almost at week 3 of flower here (white widow feminized) and I struggle to maintain humidity levels below 60%. I recently added a second dehumidifier to my operation.

The complicating factors are as follows.
I live in Vancouver (west coast represent 🖖) and at this time of year humidity levels can rise above 90%. My tent is also located in a hallway between 3 bedroom doors, the closest bedroom resident regularly leaves the window open (no problem with that, live life.) allowing humidity to enter the house/hallway. She is kind and I have notified her of my situation and she keeps her door closed to reduce effect. I also have an Exhale CO2 bag in my tent. I’ve noticed a substantial amount of liquid in the bag. I would bet the this bag is hindering my ability to lower RH. This strain also seems to be very dense, presumably rendering susceptibility to bud rot.

Im basically looking for advice on 4 questions.

1. will RH of 65 pose threat to my precious plants and their priceless flowers.

2. Does the Exhale CO2 bag benefit my growsignificantly? I regularly open my tent (2x4x5) to admire and inspect my plants, likely letting out the CO2. And my exhaust is probably cycling the tent volume about 2 times per minute.

3. Should I hook up an A/C unit to the intake allowing more control?

4. Do you like my set-up?

Intake is at the bottom left and exhaust is being sucked from top right.

Looks good! 65% won't kill you. Keep the swings as light as possible to avoid PM. PM loves hot and dry days and cool moist nights to really bloom. So an even keel temp and rh wise helps a lot. Tinker with the clip fan setups too and see if positioning makes any difference. An ac on the intake is how I run mine but I wouldn't say it's a requirement. 👍🌱

Also, the exhale bag is probably neither hurting or helping that much tbh but the only way to tell is touch nothing else but take it out for a few days a see if there's a difference in rh.

One last thing haha. Don't touch your buds ever without washing your hands first!!! I cannot stress this enough as a way to avoid unwanted pathogens in your tent.

For instance, the grapes in your fridge are usually covered with botrytis aka bud rot. 🍇

Do you

do you supplement CO2?
I do not. My setup is very much like yours. For shits and giggles I bought a co2 meter and my room/building is about 550 to 650 ppm naturally so idk. Just me in the room for 30 mins will raise that number another 100 ppm so I never bothered supplementing. 👍

Is that an sf2000? They do have the ability to push enough PAR to benefit from co2 but only on 100% like 12" away from the canopy. Other than that you're running about 750 to 900 umol, right on the edge of needing the co2
