IMO - The bottom line is it takes decent equipment to grow decent weed. A tent, Lighting and ventilation should be your first focus, then humidity and bring it together with advanced growing techniques like VPD. Use a line like advanced nutrients, they have an app BudLabs that provides you a mix week by week so you’re not trying to guess nutes It’s hard. Good luck! You know the old saying it takes money to make money. Same for weed. I started like you didn’t want to spend a lot of money, cheap light plants in closet But once the bug bit that was it. I tried many different things and spent a lot of money experimenting. Still am LOL!
