ok, so im looking into a minisplit for a new grow,

I want to have a 10 degree drop in temps when the lights go out, As an added benefit the a/c will run hard after the lights off to reduce the Humidity.

It looks like most Minisplits don't have the ability to set times and temperatures like a normal Programmable T Stat in your house.. or am I missing something?

thanks, seems a little pricey just to do what a $30 Tstat does at home depot. Any way to integrate a Minisplit to be controlled off of a Grow controller like a Sentinal?

A minisplit that powers back to the previous setting after a power outage would be controllable via a relay installed on the power feed. You could set it to high cool and then connect the relay coil to your desired thermostat / environmental controller.

IMHO a 10 degree drop when lights are off could be just the opening powdery mildew is waiting for.

Keep humidity under control. ;)

Remember, given the same h2o quantity in the air, lower temperature equals a higher relative humidity.

Also your dehumidification, relying on condensation in the AC or dehu coils will be less effective at removing moisture from cooler air.

A double whammy that could cause issues.
