Shopping for a light …
Any opinions would be great thinking about putting this in a 2 x 3 x6 space


That’s alot of light for a 2x4. Hell the new Diablo 200 would be awesome in that area. The 3p0 would be great tho if u every expand some. Think ahead of the game as lights are expensive as hell. Also going bigger now u can keep the light powered down thru the grow and save on the wear and tear of the light. Good choice wgoing with hlg also. Superior lights for sure. I love mine
