Hi! I'm new to arduino and I'm trying to design a mini semi autonomous greenhouse. I'm having trouble finding a way to heat and cool the air. The greenhouse would basically be a box of about 0.125m³ with a plant inside.
Here are some options I've found so far: - use resistors to heat the air (5W of dissipation seem enough) - use a thermo electric cooler (as showed here https://tinyurl.com/ybn8dlwb) - use a fan system (I don't really know how it would work) - use hot and cold water.
What do you think would be the best way of controlling air temperature of a box like this? Are there other options that come to your mind? Please let me know :) .
