Helping people to grow their own food!

Hi! I'm a student currently doing a project looking at indoor gardening and growing your own food! It would be really great if anyone could answer a few of my questions;

What are the main problems you face with indoor gardening?

Do you grow any of your own food? Why?

What is your favourite gardening product?

Or if anyone could fill out my short survey that would be great! https://www.surveymonkey.com/s/ZV69MD9

Thanks
