The official paper and grow-house (which contained a hefty layer of ?probably agar jelly) took only a tiny fraction of the "ink" -- this is a mixture of the "fast" and "slow" inks, in the process of fading. They disappeared entirely in the end, and I propped it on my windowsill on the wooden "easel" it had come with to await the coming of the algae.
The remainder of the ink went onto some super-thick handmade paper I'd been given for free when I bought some very fancy scented ink. It seemed to resemble the paper I'd been provided with, and again the ink successfully disappeared on this paper. I put it under my grow-house lights in a still plastic portfolio that resembled the "growhouse" that had come with the pack.
Like all very watery inks, it was a problem to manage. The ink was watery and made large, blurred lines. By the last of the paper, I was starting to get a handle on it, kind of.
I saved a little ink for my spare sheet of paper, for though the ink was getting old fast I only had one grow-house, and I had strong suspicions that the algoe would not grow except in the supplied grow-house, on that mysterious jelly.
