It's always a hard decision to make when setting up a system you want to grow in for years.
Cheap out and in a year or so you're kicking yourself in the ass or spend like royalty then lose interest later and it's another but-kicking party.
For myself with a cool underground grow area I would go with the HPS lights but don't need lights as I have more than I need now and need the heat.
For most guys they need to avoid heat so the LEDs are the way to go.
Biggest problem is that new growers don't have a clue what they need and get sucked in by the $$ signs.
'Our 1000W equivalent LED systems will save you tons of cash' but later you find out they couldn't grow a decent turnip so you need better lights. Our cheapo tent is great but soon falls apart and you need a quality tent etc etc.
There's nothing wrong as a nOOb in buying a half-assed all-in-one system for real cheap then replacing things to upgrade your grow as you learn more and develop a love for growing. That cheapo light and tent can become a great veg space while you upgrade for the more important flowering space.
It's too easy to get into a new hobby and buy nothing but the best then later find out it doesn't work for you or you lose interest and wasted a lot of dough.
Be careful out there.
