@nchareunsouk Might want to combine the nutrient solution ones into a single section, cause we're using a reservoir.
I found a way to have precise dosing through automation with an inline injection method. Uses off the shelf components.
Do we need to manage solution temperature?

Good question @nchareunsouk. I think so, considering that we're also trying to control air temperature, and water has a high thermal capacity.
I'm thinking since we're doing inline nutrient/pH injection AND having a tank, we should consider either a) an inline temp. sensor + water block + peltier PID system (like how pop machines do their cooling) or b) pre-heating/-cooling the reservoir (temp. sensor + water block + peltier PID)

@JLefebvre55. Outdoor misting systems drop the temperature of the air by a significant amount which means they draw heat from the air. So an inline pre-cooler (using peltier) would be ok, that way no control loop would be needed.
Assuming you meant the tank in "pre-heating/-cooling the reservoir", cooling the tank may be challenging due to the insulative properties of the tank however it would help to maintain a more consistent temperature if an inline pre-cooler was installed before it.

@JLefebvre55. Unless you meant the reservoir where the initial water is stored, in which case there are a few solutions to accomplish that.

Scope: Detail the purpose, function (inputs/outputs, system vs. surroundings, assumptions), and method (process steps/tree) of the system. If the method is multi-step (aka relies on a multi-part system), recurse (features) and inherit.
