How to start an indoor grow?

Recently I got access to an empty house and some money for funding a grow op. The only problem is I don’t have any experience with indoor growing. I have grown outside and i have a general idea of what is needed to grow inside. I’m just nervous about making a big investment. Lights, fans, fertilizers, seeds, soil, etc
The house I have access to is not mine but I do have permission to grow there. I’m not sure if I should start small or just set up the whole basement as a big grow space. This is a Big opportunity but also a big risk considering I have no experience growing inside.

Any experienced growers I would like to have your opinion on what I should do with this newly acquired space. What I’m really nervous about is using this house for months and then having nothing to show for it. If I do decide to go through with this I could start living in the house so I can have more time to care for them
I already started my plants that are going outside and they are healthy but I feel like growing indoors is a whole different ball game

Sounds like the dream idea to me bud go for it go big or go home

I personally find growing indoors much less stressful. You have full control over the environment when you grow inside and don't have to worry about pests or storms. The only pests you have to worry about are ones that come on clones or if you buy shitty soil. I'm probably jinxing myself by saying this, but I have never had any bugs, mold, or mildew in any of my indoor grows.

Big house? Permission to grow in it?? Man that is some our dream plans! Get a good gameplan. Invest some. Reward can be tremendous.
