Do you have any experience with expensive LED's ? Because I have grown with t8,t5,cfl,hps,mh,led. I keep my power bill under 200 bucks a month and have no need of air conditioning. My setup may not be ideal for you but for the conditions I am in at the moment it is absolutely amazing. Keeps me from having to buy medicine and I have a collective to take my extra.
Babying of plants is a misconception of yours, it is all a matter of controlling temperature without using excess energy. When I look at my boss's 8 light setup I think damn... I could do that but I also have seen the bill at the end of the month and it is hard to keep up with 8k in power/nutes/ anything else needed for the shop.
I would love to see more people saving money on their power bill but too many folks buy the cheap leds and discount them all as garbage.
[ In a perpetual system one must have a veg area , sprouting & cloning , and flower. I like to keep all three separate in case anything bad happens in one of the areas. mold/bugs/random acts of god etc. ]
