First time posting here, but I hope ya guys like this.

Kanzure from the irc suggested that I begin my diybio journey by
playing with hydroponics. Broke as I may be I whipped out a dirt
cheap hydro system.

(i have since wrapped electrical tape around the jar so light dosnt
hurt its little roots!)

I fashioned two straws together and taped one of the ends off; I then
pricked the taped end with a pin so I had an improvised pump. I don't
know how ofter I need to give my spider plant oxygen, but hopefully
this solution works.

The rest of the project was run of the mill as far as hyrdo goes
except, I used a mason jar instead of a large container.

I am hoping this project will find itself as an article for the Garage
Bio Mag. I think that there should be a teacher/kids section in the
magazine on every issue. I am very new to biology and dont understand
half of what people are talking about, so from a beginners prospective
there needs to be something for us noobs.

It wasnt my intention.. but I think this is a great classroom project
to teach kids about biology. The best bit that it costs ~35 cents,
which any teacher would adore.

cheers

Another idea is to use clay to make a mold for a seed in the future.
Make a flat pancake out of the clay, then push the seed on through so
that it has a tight fit, oriented such that the roots will be on one
side of the clay, and the stem on the other. You can then do
upside-down hydroponics.

This reminds me of my friend Phil Ross's work. He's an artist working with living systems, specifically automated vivs for individual plants. Pix of his work at http://philross.org/

I am using a spider plant bud, so the clay wont work for me.

Ive fixed my lid problem by replacing it with panty hose wrapped
around with a rubber band. Over time the hole for the plant will
stretch with the plant.

(I like Phil's work Marnia)
