Over the years I've seen about 15 plants go through the complete growth cycle. With all those plants the most verticle growth I've seen during flowering was about 200-250% of the original height. But now I'm witnessing an unknown strain that has grown 400% of it's original height in the 17 days since it was switched to 12/12. It's up to a little over 5 feet at this point.


In some ways this is a somewhat good thing but in other ways it could be disaster. Space is running out, the lights can only go up another 10 inches and I fear it collapsing under it's own weight since it's definitley not the strongest or most sturdy plant I've seen...nodes are spaced out to much in some areas. I'm dismayed by the node spacing because the plant has never had to "reach" for light. There's always been plenty of light as close to the top as possible.
It was vegged with flouros(4 foot shop and a several other supplementals on the side) and switched to 400W HPS for 12/12. It's in a natural soil/peat/perlite mix with no ferts. Also, the growth is much more stretched out than I would expect under an HPS. The light has never been very far from the top of the plant, in fact it's been just far enough to keep the tops from burning.

Is this growth unusual? Know of any strains with this characteristic? Will the verticle growth stop in the near future? Any other advice, other than the fact that using an unknown seed is a bad plan?
