I have no issue with reasonable questions. But your questions are not reasonable.
A. Is it reliable?
Please define "reliable." The system itself is just pieces of plastic. It's reliable in the sense that it's not going to cheat on you, or lie to you... Are air pumps and water pumps reliable? Is that the question? Because they are as reliable as the manufacturer and there are many. Is Ford reliable? Chevy? Toyota? Depends on who you ask and what bad press they've been getting. This isn't a question that helps get you anywhere.
B. Easy to maintain?
Define "easy" for us. Soil is easy. You just add water. Is hydro something a child could do? Sure, but they need the knowledge and the instructions. Building circuit boards is easy for people who are educated on how to do it. For Jim-Joe Backwater... not so much. As difficulty goes NFT is no more difficult than any other hydro system, but that isn't to say someone with no knowledge could succeed easily.
C. Are the results any better than soil?
Define "results" and "better." Are you talking yield? Are you talking quality? I mean, there is a reason why it's a popular method with botanists. If it can be dialed in perfectly it really does provide vigorous growth and heavy yields. But is it better than say the same genetics grown in perfectly dialed organics??? Maybe not in flavor... Hydro or Organic or Hydro Organic, they're all methods and they are all up to personal preference.
I was a noob at one time too, but these questions are... I dunno. You need to be able to get to "D" without having to ask A, B, and C (as my old philo prof. would say).
I'm not trying to nit pick but it takes time out of peoples day to try and answer a bunch of useless questions that could be answered via google so that eventually we could get to the meat of the conversation. Maybe asking the questions:
"Do you like your NFT setup?"
"Why?"
"What advantages and disadvantages do you see in your own gardens?"
"Can you give advice to someone looking to start with hydro?"
Take a look at the views versus replies and you'll see why it's important to phrase your ?'s intelligently to get people to "bite" and give you the information you're really after. You know, getting to D without having to go through A,B, and C.
