Lots of great suggestions here. Just make sure whatever you do make sure to have adequate airflow, ventilation, and if not growing an auto, have the ability to make your space have uninterrupted darkness for 12 hours while in flower.

My biggest suggestion is to post all your stuff here in our community, with good written detail, and pics. That way you can earn enough eventually to buy a decent light. Which is the biggest expense to grow good herb indoors. I used my earnings to buy a 600$ bar style LED back in the day when I grew. It can be done:)
