Your guide doesnt suck and the tard that keeps telling you all this is silly obviously doesnt need to be commenting, there are tons of ways to germinate seeds, if you have an endless supply of seeds then just tossing them in some soil and watering them may be fine, but like you pointed out you cant see if the seed is germinating/viable, i prefer to germinate my seeds hydroponically as well, number one because i grow hydro and not soil, number two i can see if a seed is a dud pretty easily, and i know which end to plant facing down once the root pops. One method I will use which i feel provides practically a 100% success rate every time is to place my seeds in a small hand held screen strainer, then take a new cloth, i use a microfiber cloth, and wrap the strainer with it. I then place the strainer under a "drip line," dripping on the cloth covering the screen strainer with the seeds inside, about one drip every 2 or 3 seconds. This works best if the water is warm, which may be hard to do, but if you have good tap water then you can just place the screen strainer cloth duo right under the faucet in a sink, if you happen to have one that no one uses, with the warm side just dripping slowly for at least a few days. Ive had seeds grow 1 to 2 inch roots and come completely out of their shell in one night, and almost always if the seeds are viable then you will experience 100% germination. I Usually wont even look inside the cloth wrapped strainer for 4 days to allow the seedling to grow nice long roots and totally drop the seed shell exposing the cotyledon, its at this point you would carefully plant them in your preferred medium.
