I hope they grow well

[Maybo]

1. I have some plants. I hope they grow well.
2. I have some plants. I hope they will grow well.

Why is 1. correct?
When should I add “will” in “I hope” sentences?

Don't use 'will' in 'I hope' sentences. You just need the present simple.

But I found some sample sentences in the dictionary that have “will”. https://dictionary.cambridge.org/dictionary/english-chinese-traditional/hope?q=Hope

The two examples that use any form of the future voice in that link can be expressed (more naturally for most native speakers) as:

I hope [that] she wins.
We have to hope and pray [that] the operation goes well.

Don't worry about what the dictionary says. Just follow my advice.

It is possible to use 'will' after 'hope' if you have a special reason, but you don't need to know about that right now.

I have said:

I hope things turn out okay.

And:

I hope they win.
