So I pulled the plant to dispose of it. It sure was nice and healthy. After being topped it was on track to produce 4 main colas. Too bad...
In the name of science I decided to see what the roots look like under the rock wool. As a bio/chem drop out, I couldn't resist.
I was expecting to see more of a root ball. This looks more like an extended stem with roots growing off of it.
Here's what was so interesting. The dark piece on the left side of the stem. I initially thought it was part of the shell from the original seed. It was inside of the rock wool and just stuck there as pulled it apart.
Looks like a burnt seed!
After letting it sit out and dry, it is a seed! How cool is that. The Big Bang plant wasn't male or female, it was a hermi.
My understanding of a feminized plant is that by chemically altering the plant, it can be forced to produce seeds. The seeds produced, first generation, shouldn't be used as "feminized" because of the high potential of becoming hermi. Second generation seeds and on are considered feminized and 99% reliable. I'll be planting this seed in a month or so...
