Ah ok...makes a bit more sense now. In my head I was imagining some sort of Frankenstein plant that had its DNA altered so it glowed....but a spray on makes way more sense! (why didn't I think of that? Doh!) Either way really glad I didn't waste my money. I'm happy with the ones I got. And finally managed to find somewhere that had cacti soil in stock! Man the garden centers are dismal right now...I expect right after Christmas would have been a better time finding plants and soil (once the Christmas stuff gets moved out!).
