Critical + is a Skunk X Big Bud cross (originally form Mr. Nice Seeds, known as Critical Mass) that Dinafem created, mostly just making a good feminized version of the original from Mr. Nice. If you read the breeders description of Critical + you would want to call bullshit, mostly because it all sounds too good to be true. But they certainly aren't stretching the truth about any of it. It really does grow fatter buds than any Big Bud I've ever grown, really does flower within 45-50 days, clones very easy (and quickly), has a fruity skunk smell and taste... and the smoke is great as a day or night time smoke.
I have grown many clones from my favorite pheno, but what amazed me was the pheno I grew outside, from seed. It was put out kind of early, around late march/early april, it grew to about 1 1/2 ft. and started flowering in right around the end of April (waaay too early)... I assumed she would grow a few buds, then re-veg and grow to be massive before flowering season, but she continued to flower!! ..and finished mid July. This gave m ea small harvest before my other plants are even ready to begin flowering. She finished in almost exactly 45 days (could have gone longer but impending rain caused me to cut it right on schedule), the plant only grew to just under 3 ft by the time it was harvested but the top cola was 1 1/2 ft long and weighed in almost 3 ounces by itself. This wouldn't have been a very good pheno for indoor, but I just got very lucky as I'm growing many of them outside but this one gave me a little smoke to hold me off until this fall/winter. The thing is, these guys flower so fast and MASSIVE that it's almost "holy grail" worthy.
If you have been debating on trying Critical (or a cross of it), or any Dinafem strain for that matter- go for it!! They are GREAT breeders and have decent prices. I put em right up there with TGA and Serious seeds honestly. The critical has made many great hybrids as well, but can be grown potent enough to win a cannabis cup, as she already has a few cup wins under her belt. Cheers!
