All I know is I'm sitting here smoking SSH watching Ed Sheeran on Palladia. Cost for a z? Maybe $20?. I feel like I'm back in the 60's. Except the weed is better. Love Ed Sheeran. Used to be the Beatles. Thanks to RIU and cobs.

Final houseing will be slightly diffrent. I went with that layout to try and get the most even spread possible. Also hlg185h c700b. They are 72v cobs. Future runs will be with hlg 185h c1400b and 36 volt cobs. Also going to offer 2 other models. One will have 1000 ppfd in a 4x4 area.

I actually don't have it right now it's on its way to be tested by a local friend. Then off to growershouse. They are going to do a write up on it. Yes this is an hid case but the final case is being produceded locally. The final build will be using cpu coolers. The are very few fastners. Heat sinks are welded.

Final houseing will be one piece on the bottom. Sides on duct ends will be 90° instead of 45° to be more fan friendly.
