I have a large yellow toadstool its about 7in by 5in, i have it under an older 14k 250w bulb, it looks slightly more brown than it does yellow, under my friends t5s it looked more yellow.. Im looking for larger size sps, lps, softies, my wife wants some gsp so if you have a big piece, that would work to. or an rbta would be nice.. Just send me offers. thanks. picture taken today.
