I've read up on the factors needed to turn purpleheart purple. I'm a little heitant to let it set outside to get natural sunlight. Winter aside, with my luck the birds will sit on it...and you know what happens next. My small woodshop has fluorescent T8 lights. Supposedly those lights give off some UV rays too, but i have read the T8 lights release only a very small amount of UV rays. Or I could set the project behind window glass on a sun exposed side of the house. But most UV rays are blocked by glass. Maybe, I shouldI just put the project on hold until warmer weather with more opportunities to catch real sun with abundant UV rays. What would you guys and gals recommend? Any advice is greatly appreciated. Thanks in advance to those who take their time to respond!
