sound like my first closet you should say f hydro but if your determined i would look into diy dwc systems (dwc= deep water culture) you can buy the pumps and timers at the hydro shop also you should work on building cloner machines out of the 5 gallon buckets. nutrients work like this in hydro check ph every day youll need a nice ph pen about 50-100 bucks and drain reservoir every 2 weeks and replace with new water and nutrients you will have to look into amount of nutrients based on stage of your plant you will also need a tds meter and a water filter, split the closet in half with mylar of poly plastic so you have one side vegging while the other is flowering. but me personaly i would go soil if this is you first time or 2 around hydro is complicated and expensive... if you do go soil look up mychorazai and make yourself a tea with humbolt honey and prozymes happyfrog bone meal and guano every 2 weeks and youl be straight add some co2 in a tank with a regulator and your time schedule(meaning speed) will be on par with that of any hydro system (excluding aeroponics which is super dumbass complicated)my soil mix is 2 roots organics bag cup of gauno and half a cup of bonemeal to 1 bale of b'cuzz peatmoss.
