So, i started this project with growing chilli-peppers.
I shall make a mini greenhouse, and i have figured out artificial sunlight and ventilation, i am also planning on adjusting the temperature so it can go both above and below the surrounding temperature.
I will try to hold the daytime temp at 70°F and the night time at 55°F by using peltier eliments.
The greenhouse shall have 24/7 ventilation (except if the humidity gets too low).
The problem is that i dont know how to keep the temperature up while having 24/7 ventilation...
I have thought of a watercooling based system, where the peltier modules warms/cools a water loop which warms/cools a radiator at the ventilation intake, but its got to be a easier way?
Please help.
Thanks
