House and Garen A & B to 800ppm.
Should I raise it for a plant this big?
To hockey4848,
Can you please let me know what brand and model number mini split(s) you used??
I am asking as I think you live in a cold climate. I live in MI. I did find a Mitsubishi mini split that goes down to 0 degrees (with a wind baffle) but it is expensive. It also only has one zone. They don't sell a multi-zone one that goes down that cold
Is the one you have a multi-zone one?
Did you have to customize it to allow it to function properly in the cold weather?
If you did customize it, what exactly did you do to it?
How well does it work for you in the dead of winter?
