Pistou forming up

here are some images of the two prepara power plant minis i have in my kitchen.
the basil pistou has just grown some real leaves, they're tiny, but perfectly formed, they look like mini versions of the pictures on the seed packet.
i have a small crop at one end of the sponge area, the other seeds sprouted along the length but not as successfully as this small bunch.

here's an interesting fact i learned;
each packet of seed sold by a manufacturer actually has a propagation success rate (i.e. 95% etc) this success rate will also vary by type...so a basil pistou sold by X may be more likely to grow than that sold by manufacturer Y!....so don't buy cheap seed...thats the only logic i can see

i'm fascinated by the growth of secret experiment, theyre drinking alot and they are getting real bushy...hopefully they'll continue on with some more 'root' growth. i think there's too many along the sponge, but i didnt want to start paring them back yet, as my daughter loves brushing her fingers over them...she knows it helps them grow!
