It is still garbage. That thing's purpose is for yields nothing more. Quality is a function of experience and genetics. Doesnt matter how efficient it is. LEDs are more efficient than HID and look at how divisive opinions are. Thats something chad would buy lol.yield is a function of surface. Quality is your skills. In my book. I'm talking about efficiency here.
You could fit a rotary garden in your 5x5 and yield 3x of the same quality. It just take the skills and the knowledge to do it.
The thing I doubt , that why I ask, is 2x1000w is not enought.
