First grow. Need advice.

I’m about to start my first grow. I’m doing autos and looking for info. Im getting a little overwhelmed with all the different opinions and information between YouTube and the internet and for some reason I think asking Reddit will be less overwhelming….? Worth a shot lol. I’m doing a 4x4 tent. For seedlings, what is the best temp and humidity? How often should I run my inline? Should I always have my little fan circulating air? What intensity should my light be running? I’m growing in Earthboxes and have worm castings and B.A.S. Craft blend for top dressing. My seeds are in paper towels atm. Hoping they’re good to plant tomorrow evening. Thanks in advance for any help! I’m really stoked to get this going.
