I too saw that video and thought I could do likewise! Mine is 10 stars across a 40" square tube of aluminum. Can't wait to see if the buds start earlier next time. G
rowmau5's videos have helped A LOT of us DIYers get started. After seeing his videos, I jumped into the DIY COB pool! I will be waiting to see if you think the 730s have speeded things up a bit.
So from your pics, are you going to run your power supplies separate from your light bar? Mine are currently separate, and I have not decided yet. Mine is a TNT build (that is tape-n-tyraps). I am still gathering experience and information before I tie it all together with some aluminum angle like yours. Thanks.
