You want other fast strains?
I don't know of anything that is really "done" at only 5 weeks, but I can think of several that will legitimately finish in 45-50 days, or around 6-7 weeks.
-A few of the old school pure indicas like Afghan #1 and Hash Plant will finish that fast.
-Green Crack (clone only) will be legitimately done in 45-50 days. I've run the Sickmeds Green Crack S1 from ceed, and my pheno was legitimately done in 50 days from clone (took a bit longer from ceed). You can see the pictures in the grow report in my sig.
-You already mentioned Critical plus.
-There is a strain called "top 44" that is supposedly done in 44 days, though I can't comment on its quality.
-Silver Pearl is another good old school strain that finishes in about 45-50 days. Sensi used to offer it, but I think its "clone only" now, probably circulates more in Europe than in the USA, and you're probably going to have a hell of a time finding any.
-Bogglegum is supposed to be a 6-7 weeker, too.
I'm sure there are others; try Google. . .you'll find some.
