That's very hard to say, the PE definitely has ruderalis in it. But the 90 Day Wonder from what I've been told about the history started in the early 80's in Hawaii, someone brought over Might Mite and started crosses with some local sativa strains. The result is a plant that will finish in 90day anytime of the yr. Green Harvest choppers would do complete searches on a rotation that would take 4 months. Hence the 90 Day Wonder could be planted right after a chopper sweep of the area and be harvested prior to the next sweep.
Anyways the PE finishes in 80days the other in 90 so I would expect the kids to finish somewhere in this range. And hopefully it will be a little less finicky than the Auto.
Here's what I've found about Mighty Mite (this is the
article I pulled the following paragraph from)
During this time Canadian growers on British Columbia's Gulf Islands also experimented with early maturing outdoor varieties. They noticed that some plants always seemed to flower much earlier than the rest and they started exploring those seeds lines in search of good plants. This eventually gave birth to the Mighty Mite strain that has now become famous for its extremely early, if not autoflowering abilities. There is wide speculation on whether Mighty Mite actually contains ruderalis genes. One thing is for certain– it is one of the earliest outdoor plants that can be found. The Mighty Mite has since spread to both indoor and outdoor grows where it has been hybridized countless times in order to create early maturing but potent varieties including Guerilla Gold. It is sometimes difficult to draw a line between extremely early "Semi-Auto" and fully autoflowering plants because they can be seemingly similar in behaviour although they might have totally different pedigree. Perhaps there should be some distinction between the two, where one is classified as autoflowering based on genetic criteria and the other is considered a normal but early maturing plant that has acclimatized to the colder, northern environment. Some of these strains date back as much as thirty years, meaning that the plants have had time to grow accustomed to the local environment and thereby developed traits that ensure their survival. Coincidentally, many of these strains are pure or sativa dominant which would, in an indirect way, support the theory that cannabis ruderalis stems from that side of the family tree. These plants are not autoflowering per se, but so early that it can be difficult to spot any difference.
