How to produce clear agar

Hello,

Maybe this is a weird question, but I would like to make a very clear see-through agar. That way I can grow a plant in it and see the roots grow. Im using agar-agar, the Japanese foodstuff so it might not be possible to make my agar that clear. If you have any tips I would be pleased to hear them.

Im not a student of Biology, but Pharmacy (in Holland). Still I would very much like to do this experiment.

Thanks,
Stefan

I did just today try the experiment with agar-agar, it seemed to be clear at first, but now its almost milky. Still with a bright lamp you can see the tulip-root (translation...) in the gel.

If you would like to try it, I used
10 grams agar-agar
100 grams sorbitol (humectant)
2 grams paramethylbenzanoate (conservant)
4 doses of clear liquid plant food for 1 liter
1 liter of water

added the tulip-root when the agar was almost hard.
