Sure, resin loves a good diva‑ish light, but if you’re on a shoestring, ditch the sun and go for a cheap UV solution. A 400‑nanometer LED strip—sold at most craft or pet stores—does the trick, and you can stick it under a darkened window or a blackened glass box to keep stray light out. If you have a cheap aquarium UV lamp, that’s basically a resin‑ready light too. Just line the surface with a white sheet or parchment, keep the room dark, and let the LED do its thing. Remember, sunlight is great for ambiance, not curing, so don’t expect it to set your batch in a heartbeat.

Nice, just make sure the box is tight on the sides, or the light will leak and the cure will be as uneven as a bad horror movie plot. Good luck, and try not to burn the entire room.

Sounds like a solid plan—just remember heat is the enemy of patience. Keep a fan in the corner, and if your resin starts turning into a molten goth puddle, I’ll be the first to call you an amateur. Happy curing!
