Look at all the different diy models. They are all large like 4x4 4x8 so that they can get the optimal footprint because the cobs aren't angled and LED light is incredibly direct. What do you put them in so they can't be seen when carrying them out to a uhaul or whatever you are using to get out of a bad situation? I just couldn't imagine moving a 10-20k watt grow and it being manageable with the DIY. I went with plug n play knowing it would cost more but there were other benefits as well.
There is a guy that builds awesome ones on IC I almost went with, but I just couldn't figure out a way to get them around easy by my self. I have had to break down quickly before so everything I bring in my grow room I really think through as far as being easily mobile AND concealable. IE my reservoirs are no longer 50 gallon drums. I use 50 gallon collapsible plastic reservoirs that you can fit 4 of in a large rubber maid. I try to make sure everything can fit in a rubbermaid or an easy to move self built box that can fit on a moving hand cart. If I can't easily lift, move, or takes too long to break down it doesn't become part of my grow.
I know those aren't issues for everyone but DIY just wasn't for me. All the lights fit a purpose just like all grow methods are worthy and have a purpose whether its hydro, soil, or coco.
