Newbie Hydro grower

I'm a long time smoker (first time in Vietman), first time grower. I have ordered a stealth grow cabinet from Ebay that should be here next week. (Photo attached). I have all the stuff I need to get growing hydroponically. I have spent the last two weeks reading info from the internet (forums and how to) and watched a couple of different videos. This hydoponic growing is all starting to come together, but I have a few questions for all the experts out there
Here are my questions:

I've seen alot of advice to newbies to start their first grow with bagseed. It appears the success rate on first time hydro grows is piss poor, and you shouldn't throw your money away buying good seeds. This old fart didn't have bagseed, so I have some BC Mango, and Northern Lights coming. If successful at getting any of these seeds up to a mother plant I plan on cloning down the road. Is it possible for a first time hydro grower to pull off a decent crop? I know there is a steep learning curve with this growing stuff and there is nothing like on the job training, but I hope by buying good equipment and doing my homework in 2 or 3 months I'll be smoking some stuff that will knock my dick in the dirt.

Was BC Mango and Northern Lights a good choice for a Newbie? If not, I'm open to suggestions.

Thanks to all in advance.

Hey Man, welcome to Rollitup! It sounds like you have done your homework, so you get a gold star. You can start with your purchased seeds, you'll just be extra careful with them. You'll have to decide how you want to keep your mothers, and that will determine how you germinate your seeds.

I just watched Platoon again the other night, that film always affects me.

HTH

I grew some dank shit on my first hydro. Have some confidence.
