Hello everyone. New member, first post. I wanted to show off my custom LED build stealth cabinet. It's a work in progress, and I'm happy with the results so far. This is also my first grow. I researched LED design before the build, and a little bit about weed growing. But first some pics. These are 1-day timelapse, with an outdoor "control" for comparison. They begin at day 27, which is the first day in the cabinet. Prior to that, they were on the window sill. In short, this is 17 days of growth at a constant 90 W. I made some gif timelapse animations, but this crummy host doesn't animated them. Save and view them locally, e.g. with web browser, and they'll work.

About the build: it's 3 color; 2x red and 1x blue. I wanted another blue frequency but couldn't find it. The red and blue are on separate drivers and controlled by potentiometer. I designed and verified the build at 100 W total led input power, 50 W each channel. I'm running at half-power on both channels now, and my wall-meter says 90 W, ~10 W of that are the fans. The cabinet is oak frame with 6 mm plywood siding. Strong and light. I sealed the joints with silicone, but the doors need foam seals. It's pressurized with a couple 14 mm fans, and exhausts out a carbon filter. Lined with some diamond aluminum paper stuff. Using good flower soil and standard tomato fertilizer. There is a /lot/ more I could say about the design choices, but that's enough for today.
