When do I harvest hillbilly pumpkin?
Just wait for them to soften or once the caps have inverted?

From your POTD post I’d go ahead and pull them!

For next time... It is better just to float this sub and clear the top with a bread knife?

Quick question: if a small room (~130 sq ft) has 32 monotubs active would one have to worry about FAE of the entire room? Would a small air purifier and a non-air tight door be good enough to supply the room with enough fresh air? Is that even a thing?

---

32 tubs is a ton. The need for FAE is dependent on a lot of factors.
If I had that many, just because of the sheer volume of invested time/resources, I'd probably invest into an air purifier.
The growth process gives off Co2 so while the environment in the tubs is relatively isolated, the air being exchanged could possibly have high-er levels than desirable. Spend $50 and buy a Co2 meter/sensor for the ambient air... if it's high then add some kind of airflow/fan to exhaust it out/clean in.

For sure. Looking for someone who can speak from experience growing a lot in a tight space

I agree with Derrayld: open the door. The only way to reduce CO2 is with a flow of lower CO2 air.

A purifier is unnecessary here, unless there is also a concern about particulate matter. Gases can’t be filtered, only particles.

Cheap C02 sensors don’t work. Look for one with an NDIR sensor. The Aranet seen below is a decent quality sensor at a good price.

In the photos you see the sensor in open air on top of a tub then inside the same tub. The tub is Pasty style with 5 holes high on the short sides, 3 low on the long sides, inverted lid, no tape.

There are 8 full size tubs and 6 shoeboxes in a 7 x 2.5 x 8 foot closet. That’s 140 cubic feet. The closet door has been open all day. There is a fan drawing air in through a window (currently closed due to time of day) and out through a door.

As you can see the levels are well above what’s comfortable for humans. That concentrated C02 coming from inside the tubs has to go somewhere, and that somewhere has to be as short a path to the great outdoors as possible.

Hard to get a good pic without taking the lid off. Wasn’t sure if I should do that yet.
