I teach at the college level. I have found that in the last 20 years the ability of people to read and write correctly keeps going down every year. for me, this is a major scandal, but then I write and teach for a living, so of course, it would seem that way to me. But I have a way that you can write how you speak and still be punctuated enough to make it easy to read.
Say it aloud and listen to where you stop. That short pause between the different things is a period. When you pause after each sentence, use a period.
When you pause in the middle of an idea to share a list of things with us, then use commas.
"I planted in rockwool cubes." If I was saying this, there would be a pause after the words cubes. Stick a period there.
"You know there are 3 ways to germinate, paper towel, final pot, or a germinator machine." Put commas between the list of things.
I know this sounds like I'm doing it for baby lessons, I don't mean it that way.
I do this with students also. It's a quick tool to keep yourself understandable online.
I hope it helps you, I know it has helped others in the past.
ps: I used to be a grammar nazi until I married a Hawaiian/Chinese mix. English is a pidgin language here.
