Keep it simple. Try to control climate and provide proper VPD as best you can. Do things in a basic way to form proper baseline expectations and at least a little familiarity with genetic diversity -- wide range of results simply due to genetics. Read up on Daily Light Integral to properly measure and conceptualize light provided. Understand how it is proportional to hours of operation and intensity of light. It's not about either of those factors on their own, but how they multiply together. Rate x Time is the total energy provided.. not just "i gave it 18h of light" - that's half the story.
Once you have a proper baseline, you can test out all the gimmicks and bro science that promise the world. You'll more easily recognize what is a total waste of time and what has a real impact on results. So, get a handful of grows under your belt until you confidently grow healthy plants seed to harvest and see a little variety in outcomes while doing that. At that point you can recognize when you try an overly sophisticed process doesn't provide a discernable benefit warrantingn the extra effort, lol. This is actually very common.
People have all sorts of elaborate processes for seed germination and think their way is the only way or the best way. Truth is, as long as you don't step on your own dick (or flaps), you should get 95-99% successful germination rates as long as it isn't old seed or poorly stored seeds. This is not a skill, lol. I will say doing things well results in greater consistency. Doing things well means vast majority of sprouts will break ground (or whatever equivalent is doing paper towel method, which has a bunch of extra steps and you have to fiddle with a taproot, never a good idea) within 2-4 days of planting. May have a few stragglers after that, but most should all pop quickly. If in cold climate, a heat mat + thermostat to keep medium at 76-80F will help immensely with consistency. If you live in a warm climate, this tool is not so useful. It doesn't matter how you get there. Though getting there with the least amount of effort is a better way, all other factors being equal.
In my expereince, doing things "better" has the most profound effect on consistency. Doing things better will never turn a weak plant into a monster. It does improve results, but the most profound effect is consistency. Doing things well means less deviation between plants. Genetic variety can be profound, too, but on average people like to blame outside sources for problems or unmet expectations before they reflect on their own behaviors and their impact on results. "It can't be my 200dollar bottle of fertilizer!" type stuff, lol.
Some things are true but have minimal effect as far as what the eye can discern, like blue vs red wavelenths effects on growth patterns is a good example of this. A greater proportion of blue wavelengths will not turn a lanky plant into a squat plant. It will have an effect just not a profound effect.
Read articles and guides on cocoforcannabis.com. Avoid user-submitted forums and even this grow question area. Rife with personal bias and drawing conclusions from incomplete or completely missing data etc.. Even if you don't grow in a soilless medium, the other infor about managing the plant will still be the same. Soilless/hydro has some differences in irrigation procedure and how you provide nutrients, but otherwise things will translate the same.
Form rational expectations before wading into the magical world of bullshit products that over-promise and under-deliver while costing an arm and a leg at times, lol.
