Ruva,
First of all, I agree with the idea to keep mothers and clones in the same room, no need to complicate things.
Below is a link to a "how to" RDWC system called "The Bio Buckets". It's the method I used for my setup and it is by far the best and easiest method of hydro I've used to date (I've previously done DWC, drip systems, and ebb/flood).

This guy's setup is over the top (in a good way), but I built my system more simply. My system can run up to 12 buckets with a single reservoir (plus a 27 gallon auto top off reservoir), a single pump, and a single 3 inch PVC return line. It took a decent amount of work to set it up, but considering the work you've done thusfar in the room, this will just be a final step. The RDWC method is much easier than I expected and I've been able to maintain much more consistent Ph levels than with other hydro methods.
Now that my system is set up and running, it is so unbelievably easy to maintain, it's crazy. I honestly spend about 5 - 10 minutes a day at most working on it (and often that's just looking at the plants because my Ph and nutrient levels stay consistent and don't require any work) and I'm able to skip days at a time, no problem. With my automatic top of reservoir, I could literally leave for a week and not worry about it. With my previous methods, I would have been too concerned about Ph flucutaion to leave for that long.
Even though the author of "The Bio Buckets" is not the best speller or writer, it will be clear enough to understand. Take the time to read it and, since I sense that you're on the fence, I think you'll be swayed to do hydro.
The basics of hydro are very simple and you only need a few tools for the trade:
1) A Ph meter - about $40 on Ebay and a very handy and easy tool to use.
2) A TDS/EC meter - for metering PPMs or parts per million of Total Disolved Solids.
3) A Reverse Osmosis filter - not absolutely critical (you can use tap water), but it allows you to start with completely clean, pure water. It's also nice to have in your house for your drinking water. About $120 - $150 at Depot, online, etc.
That's it man!
My favorite thing about hydro is that if there is a problem with Ph, nutrient deficiency, toxicity, etc., you can immediately bring the water back to where it needs to be for each and every plant in your system because they're all on the same "circuit" of water so to speak. You know with each and every plant what their Ph and nutrient levels are at.
With soil, you can have different Ph and nutrient levels in each bucket. So if you have 12 plants, you've got to individually test Ph and nutrient levels for each pot and adjust each one. VERY time consuming....VERY. Plus, if and when you do have a problem, you have to flush, test, flush, test, etc. etc. It's much more difficult to get levels back to optimal, and it's more difficult to really gauge where your true levels are compared to simple H2O hydro.
Because so many more people in the world grow veggies, fruits, houseplants, etc. etc. in soil, there's a misconception that hydro is more difficult and harder to learn. We grow up as children thinking soil is the easier method because that's all we see our parents and grandparents doing. This simply is not the case...now, more than ever, with the absolute abundance of information on the internet, it's all there for you to learn, practice, and succeed.
