I was using the waterfarm modules for moms for a while, they are good but need some modding.
1. Drill out the holes in the brown bucket with something a bit bigger to prevent from roots getting too big and clogging the holes.
2. Instead of the standard 90* angle for the level meter hose, use a T connector and put a 1/2" ball valve on the part of the T pointed downwards so you can easily extract the nutrients and check your ppm/ph.
3. Cover the top of the buckets with panda paper or something of the sort. I had lots of problems with splashing from the drip ring.
4. Install a bubble curtain/wand in the bottom of the bucket to help keep high DO levels.
If you're using the 8+ reservoir setup with the waterfarms I'd recommend converting it to a recirculating system as this will help you manage everything a lot easier.
I have also used an aeroflo 60 site, and a stinkbud system for aero and both worked really well and are super easy to maintain and keep up with. The aeroflo is a bit clustered for my liking and stinkbuds is a bit better with the spacing.
I've made some DWC roughneck containers when I was starting out and if you're on a budget they're not a bad option to keep things simple. The only problems I ran into with them was checking the nute solution ppm/ph as well as crowding as well.
A newer system I've been reading up a lot on and am currently building a DIY of is the Current Culture H20 system. (

I've seen some really killer results with this type setup and it's very versatile letting you grow 2 or even 100 plants if you wanted to with enough light/space. They rely on mixing the nutes constantly and moving the solution constantly keeping it thoroughly mixed while also adding high levels of oxygen to the system to help keep the DO high.
As for messy, I agree, I ran some moms for a while in soil and just didn't like the dirt in my super clean rooms. But hydro can be a PITA too if you're not cautious with leaks and leak protection. I've flooeded my room a few times in my time growing and it fucking sucks, but with some tarps and a wetvac it isn't something a joint and 10 minutes can't take care of.
I think the main difference between soil and hydro is cost, yield, and taste. Hydro's been a much more expensive experience for me, while soil is very simply cheaper. I also feel that since you're able to control your nutes in hydro a lot more you're able to maximize your yield more than soil. Under the right conditions though, both methods can have great results and some people like the hydro smoke more and some prefer the soil.
In the end it really comes down to personal preference. Do what you like to do, and not what others tell you, and enjoy this hobby.
