in uk the raw materials or rather the Led's would be pretty costly. or they were, i might have a look and see what's changedI'm leaning towards building one seems super easy. Just gotta do the reading.
Oh aye, you need a whole load of other stuff as well, but as he explained it all those gubbins can be outside your room with just the lights in there. The current LED panels are all in one type set ups.aye I've seen them for Xmas trees n thought that'd be good but I dunno about the workings. All the panels have a bit more to them than just a big transformer plug on the end of the cable.
an led grow cage with semi rigid wire would be pretty badass to grow in.
