A newbie in need of guidance

Yo, so I've got everything in order and I'm ready to start making purchases towards my very first grow set up. Indoor. I've already got my tent. It's a The LAshop 4x4x6.5 Mylar reflective tent. I've got my seeds already. I just need to be set in the right direction in regards to filters and lights and fans and what not. I have no real experience in this and I'd like my first one to be a good one, ya know? I'll take any and all suggestions!

You will have to decide if you are going with Hps, LED, Cobs, T5, CFL ect.. and then you can decide on your ventilation and what kind of medium your going to grow in or hydro. This all will matter when it comes to dialing in your environment for your plants. Lots of factors you will have to find what you feel is the best for your space you want to grow in. The space you decide to put your tent into and your lighting and ventilation will all factor into your environment. Aka like if you will have to run AC and how you will control temperatures and your RH.

You didn't list any goals so I built a list of expensive items, I didn't give this a lot of thought. Here's some items and approaches I've not tried all these items for example the drip system I would just build myself. Just put it there to fill the spot. Not saying you should go buy this expensive stuff I didn't verify carefully some stuff. I'm just showing you what happens without giving us direction.
