The two Shackzilla are going to have huge colas. Tall Hazey Shack looks like she will have two 15 inch tall colas, I can't quite believe the size of them. I will get a tape measure so I can get the actual measurement, but they're huge. Looks like they should all fill in too from the size of the buds now before any sort of swelling. I'll get some photos tomorrow. Truly insane looking though. Two shorter colas too of about 12 inches to back it up.
The other one, Shiva Shack, has an already filled in cola that is about 9 inches in height which will end up fatter than Biggie Smalls rhymes. I've had a Mad Shack (Mad Scientist X Shackzilla) grow the biggest cola of any plant I've grown so far, this plant has very similar characteristics, could be even fatter. Mad Shack cola was fatter than four coke cans put together. Very tight structure to Shiva Shack, not quite closed, but far more so than the others. I will stake them both later this week and when I do I will spread Shiva's stems, open the middle up some - to aid air flow as much as anything, big buds need forethought and good air flow.
The two Jacks are looking just great. Such unusual looking flowers on both of them. One clearly 2 weeks (ish) ahead of the other - probably an 11 and a 13 week (though could be a 10 and a 12), we shall see.
Oh and damn hot here right now! Day time's 80-83 max - night 70-73 min. Hopefully get a break in it soon.
