I don't need to add anything to that mate. U have it covered. A chiller is a must for none media hydro. I have done it many times successfully without one but it's Russian roulette. I've had my fair share of root probs over the time I've been growing, a chiller would have prevented most of them.
I still think the dwc gives better results in a true like for like scenario. The speed of dwc growth is hard to match when done effectively. Not only that but u could veg 4plants 2 weeks and get the same as the 1 monster plant that's vegged 3months.
As for light u are right capn. It's true 1gpw and more is possible but this technique really refers to sea of green growing with lots of small plants. For someone like myself who has no regards to plant numbers it's no problem, that is when I can be bothered to set up 300 2litre hempy pots which are filled with perlite that I constantly knock over and is time consuming to manage. In my opinion it's better to never really have more than 9 plants per light. Adding that extra light will absolutely more than pay for itself in produce. When looking to add anything to ur regime just ask ur self how it will improve ur product and will u see a return on what it costs to put in.
