So, I think what you need is some help to narrow down, based on your environmental factors and budget, a kind of system that you can put together. I don't think anyone has a list of Amazon parts all in a kit form like you're maybe thinking? But I think that maybe after some discussion you can learn what you need and then do the legwork to find all the parts on Amazon.
After a shit ton of research I put together an 8 x 5.6 gallon RDWC system built entirely from stuff on Amazon - but it wasn't cheap and I don't have a list of what I used. Some I needed, some I changed my mind on - it was an evolving build. I use this for veg and I flower in a different, bigger 6 plant Under Current RDWC. I have moms in coco and clone with the EZ Cloner right to the veg system.
I had a hard time in the beginning with root root and other issues - it definitely was more difficult than I had thought - and I went to school for water treatment engineering. It certainly can be done - but there's a whole lot of legwork to do to learn how to dial it in. It's a super delicate way to grow.
If I were to do it again, I'd probably grow in coco with an Autopot system. Super easy and almost foolproof.
But, if you're determined to do it and are confident in your research - lets start with the basics:
- What space are you growing in - basement, attic, garage? Is it heated, cold cement floors? What's the ceiling hight and what type is it - drywall, bare floor joists, drop ceiling? What is the high/low temp average in that space currently? What are the dimensions?
- are you going to veg and flower in the same system, same room or will they be separate?
- How many plants are you looking to do? If you had unlimited space, your limiting factor with your budget is going to be lighting. So, that's what will ultimately decide your sizing and # of plants - depends on your light.
- Do you have the ability to modify the space if you need to improve the environmental conditions? You'll probably at some point need to control the temperature and humidity and will need to account for good ventilation.
Lets start there as a baseline and that will get you a starting point.
