I am new to this and don't want put too much money into this to start. I have been looking at the $50-70 LED grow panels on amazon that advertise as 300w but realistically I know they probably only put out about 120w. Will this be enough for 2 plants? Also I really want to begin growing by jumping into the field of autoflowering plants. I've been doing a lot of research but really can't find much about these lights anywhere so.

You can certainly grow a couple of plants under a 120w fixture-the only question is how well.
Although you don't mention your medium, When I did a closet grow this winter with a couple of girls in 5gal DWC buckets, they needed a 2x3 space to really fit-that's 6 sq ft and 'blurple' panels really need ~ 40w/sqft so in reality each of those '300w' fixures would be adequate for a single plant.

These lights have a useful coverage area of about 1.5' x 1.5' - space for about one decent sized plant.

I'm growing in soil. I was thinking of using one 10 gallon pot divided in the middle to do 2 plants. Thoughts?

doable, I have grown small to mid size plant under a 'blackstar 240' pumping out about 130 watts of red and blue LED, but i was working in a 16 inch by 16inch by 4 foot container which is only really good for one plant, if you have more space good, you will need it.

Well, at the risk of repeating myself, those lights REALISTICALLY have a coverage area of 1.5' x 1.5', enough for one plant, barely.

Don't be fooled. If your on a budget that's cool. Here's my auto tent, 2x4x6 exactly what your going for and cheap. I grow photo's but i use this tent for quick bud. 2 shitty lights that I payed $60 total for and a cheap fan. Consistently pull 8-12 oz every 10 weeks.

I bought them used $30 each from my neighbor. Chinese blurple LED. Haven't looked them up but they're from "Kingbo"??? They pull 120ish from the wall. Probably better lights for the price out there but they have done fine for me.

Make up your mind before going any further. If you think you might get into growing full time buy something better. Lights are an investment and they directly affect every part of growing. If this is 100% personal smoke, a budget led will get you that. If you want more than 1 or 2 plants, just save your money and get a quantum board or cobs.

I'm thinking of investing a little more money say $40 and buy a couple of 50w boards and angle them towards the plants.

Low watt blurple boards are horrible. 1 single "300w" blurple would be better. Whats your max budget???

It is going to show in your yields....

My brute force method uses 3 $50 100W strips on a $90 driver for a 2x4...
I would save up for that extra 150 and change you will need to slap it all together.
