Well there is good news and bad news. Good news is, You can learn lots with a small NFT system. Bad news is things can get cumbersome when you want to move your tray around to get a different view.

I bought one of those 250W 22L NFT systems a few years back and that was how I first leaned to grow. It isn't easy, but If you get good advice early on it helps. Expect to be amazed and also expect to be disappointed.

Two pals recently grew 3 plants (in soil tho) using a tent of some sort and yeiled a total of 15OZ which is around 5OZ per plant dry weight. Their plants were huge and it was their first attempt.

I'll post a couple pics, once i reboot with my other HDD plugged in
