gel cups? what are they?

got these from a friend a while back

never got around to usin them of course .

considering i dont know what they are?

Looks like some sort of KY type sex jelly

When you buy bambo plants, some times they put 3 or 4 stocks with roots in a container with the gel like that, and it keepts the roots alive for a certain period. But bamboo is really hard to kill. In other words, its super easy to grow so there for this shit preserves the roots..

yum looks like pudding containers

You can also use these to clone. I have seen a side by sidewith these and they did not perform all that well.

so i could use them outside? to hold water
