So this is day 7 of 12/12 - and they just started to really stretch the past few days. I imagine the JackBerry will stretch for another week or two, and the Chinese KF7's will continue to stretch for another 3 weeks to a month. I would guesstimate that 80% of "Screen 1" will be the KF7's.
At this point I am definitely more impressed with the KF7's. They handle increase in nutrients without problems, have little or no negative repercussions from trimming the shit out of them, and they are growing much faster at the moment than any of the JackBerry. The one that I mentioned at the very beginning of this thread, with strange, extremely sativa-like leaf structure, and that originally looked like shit, has recovered fully, and has the juiciest stink I have ever smelled. The other, larger KF7 smells similar but not quite as pungent or flavorful. I would compare their aroma to bubblegum and berries. Kiwi/Greenapple maybe? It is hard to put a finger on. Anyways, these are BEAUTIFUL plants. very very pretty to look at. The juicier pheno also grows more like a vine.. so the stalks are rather weak, and seems perfect for scrog. If I could do a vertical scrog grow with this baby I could only imagine what the yield might be.
Most of the JackBerries have a distinctive "purp" smell to them..(at the moment) kind of musky skunk, and some are stronger than others. The best pheno I have exhibits strong kush-like smell, and has bushy structure- "George Bush" - looks like a heavy Blue Berry influence, and very little Jack.
The JackBerries also are temperamental when it comes to nutrients. I know that DWC is a very effective source of nutrient uptake, but damn, my ppm has been below 600 on all of these.. even the KF7's. The JackBerry seems to prefer ppm's 450-500. KF7 likes 600-650 right now.
Clones are at 250ppm, 5.6-5.7 pH - being misted twice a day, and fed once a day. Still no roots yet. I took 3 "PineCone" pheno clones (from the larger and more vigorous JackBerry plant) and 3 from "George Bush" pheno. (bushier, slightly shorter, but with many more bud sites)
So far, only one clone has died, which was one of the PineCone phenos. They are 4 days old I think.
