Seed germinator help

Hey, im new to arduino and was looking to build a project (maybe a bit much to start with, but i can break it down into parts if needed)

Looking to make something for a little seed germination box with some automated features and tech (mostly to learn how to do it, and cause im too lazy to look after them so ill learn a new skill and build a machine to get out of it... lol)

Might be easier if i list some components im thinking and a few other things first.....

-This will be the base germination box im going to start with:
https://a.aliexpress.com/_mNuRAyO. The one with 3 boxes/light units to start with, but id like the ability to add units if required

-a heating mat roughly the size or slightly smaller than 145mmx185mm. Preferably self adhesive... i was looking at some 5v usb options but im not sure if they get hot enough. Id prefer not to play with mains power if possible. So any sugestions on a heating mat suitible for plants that i wont kill myself wiring up

  • ky-15 (or better sugestion) to check temp to tigger heater and actuate a servo to open or close the vent at the top of the box to control the humidity

-water level sensor - https://a.aliexpress.com/_mKFhXly to trigger a pump to trop up the bottom of the box

-The pump: https://a.aliexpress.com/_mPcB1QI

-water atomizer: https://a.aliexpress.com/_mM6gYGA to make water and humidify prob just gonna put it on a timer with the leds, either when they r on or off (not sure whats better for the plants)

-Nextion hmi display to read sensor data and alter things like timers and intensity of things Just https://a.aliexpress.com/_m0qShEW

Looking for recomendations on best choice of arduino

Thinking of lopping the usb plug and swapping for another plug so i can choose what lights r being used and when.

-photoresistor to make sure the lights arent turned on during the day when not needed

-Rtc module (not sure how important this is for schedualing events on time, so let me know if its needed

-custom pcb with room for expansion if i want to add more pods.

-what will i need to power this and what other components would i need to make this work???

I know its a bit, but im sure i can get away with one thing at a time until i get to the coding part i need to learn.... any help would be much appreciated...

Why would you buy that? The picture shows seedling growing boxes, but look at the product description:

Product sellpoints
Fishing rod: The fishing rod is made of aluminum alloy, which is durable and has a long service life. it is an indispensable tool for fishing enthusiasts.
Use anywhere: The fishing pole holder is easy to use and can be used in both freshwater and saltwater. it is suitable for all kinds of fishing rods, such as bass, trout, pike, salmon, etc.

If you order the product on that page, what will arrive? Seedling boxes, fishing rods, or something completely different?!?

Buy and UNO, a breadboard, an LED, a pushbuttin and an assortment of resistors.
See if you can write a program that makes the LED blink when you push the button.
Go from there.
