Yes it is. I found these 2 threads while researching member berry for my next grow the diary is incomplete but helpful in stretch and those buds he has a pic of in week 11 don't look close to done so plenty of time to build more frost.
There is another member berry grow online in grow diaries his looks like his only grew about 6 inches after he switched to flowered but he topped his also so u might see more. I have member berry up next so interested how this turns out..
