Welcome to the forum @HippieWannabe .
Guys I am 1 of the caveman simple growers here. I wrote a simple rockwool method that works 90+%.
I use water sprout to soil. Straight to soil and this method for multiples when refilling a tent and cooking my soil.
This method is friendly to all grow mediums. Hydro/coco/soil. If you would like to read it it is linked here. Do not need the big propagator. Just a clear lid on a solo will work.
Hope this helps. Starting beans and killing seedlings is a new growers bane. Once in a good veg state cannabis is tough. Patience and leaving beans and seedlings alone is the key. Start them right then letem grow. If you believe they need water much you will be incorrect. A taproot can grow to the bottom of a pot in days seeking water. A good thing. Gl and lets get you guys growing. Many ways to start and all are up here in the forum. Pick 1 you like and roll with it.
