Sealed 4x4 dehuey sizing

Getting ready to seal the cabinet up.

I'll be running 16 plants in 10L airpots. LED with driver mounted remotely, CO2, 1.2kw AC. Dehumidifier will be housed in its own alcove and plumbed in.

I intend to vent intermittently. Average ambient humidity taken from a local weather station is 80% annually, give or take 5%.

Having trouble finding concise info on sizing a dehumidifier to run during the dark cycle. Any tips as I'd rather not wing it!

Bump. Thinking of going the Mitsubishi MJ-E22. Its a 22L/day (46 pints) and has auto resume after power failure. It's an expensive piece of kit.

I'm just not sure if it will be overkill or on the boarder of what I'll need

I use a 50pint in my 4x8x8 semi-sealed room w co2.
30pint was weak.
70pint was overkill.

They all produce heat when their compressor runs.

Best thing I did was setup the gravity drain.
My next 50pint will have wifi! I want to schedule when it runs and at what settings.

I run a 70 in a 5x10 but it is controlled by an environmental controller.
I would say slightly "too big" is better if you have control of the cycling

Probably go for the one I posted then!

It doesn't have wifi, but it has auto resume on power shut off so I can wire it up to a microcontrolled relay.

The heat shouldn't be an issue, the ac should be able to combat it
