Woo I found the old 50/50 bulb in the garage (I thought it was in the attic..... it is SO HOT up there). I put it in place were the 10,000k was and I broke one of those high heat rubber bands.... I turned it on and you can tell the purple tint. It looks better than I thought though. You can see the purples/greens/oranges from the ricordea/star poylps/ mushrooms/ bta better than before. The bulbs are old so it's not really a good test to tell, But I'm gonna get the 50/50 and actinic replacements in a couple weeks and see how it goes for the next 6 months.
