How much money will it cost to grown a few plants?

As im a very newb and each sites says their own opinion some says no more than 100$ some says to get started 300$ and some says it can reach 1000$

So we talk about no more than 3 -4 plants i dont know yet for sure but lets says 4. How much will it cost including from the electric bill to the equipments.

I guess the more it cost is just a better equipments like this.

But i dont want that very shiny new wonderful looking stuff, but a very healthly weed.

Thanks

Only you can decide how much it's going to cost you. You could have a price point, and then decide to grow in a cardboard box or whatever instead of buying a tent and shave a hundred dollars or so off the startup costs.
