Using coffee grounds on tomatoes

Question

I’m a student researching about coffee grounds. I’m from the Philippines. I would like to ask some questions.

Do you use coffee grounds in planting?
Do you use it on tomatoes?
Do you use coffee for watering your plants or do you use it as a fertilizer?
If you’re using coffee grounds, where do you usually use it – in vegetable plants or in fruit bearing plants?
Does it help your plants grow faster or no? Is it effective?
Does using coffee grounds increase your expenses on planting or decrease it?
And, lastly, if you are using coffee grounds, what coffee do you specifically use?

Please answer my questions. I will appreciate your consideration. By answering my questions, you will help me with my Investigatory Project 🙂 I will wait. Thank you so much! I really need answers.
