Sweet Critical CBD Feminized Seeds by 00 Seeds · High CBD, Low THC Strain for Relaxed Effects

Sweet Critical CBD by 00 Seeds is a balanced feminized strain delivering 18–22% CBD and just 0.3% THC, offering smooth, non-psychoactive relaxation with rich, sweet terpene flavor and heavy resin production.

Ever feel like your go-to strain hits too hard or doesn’t quite calm your mind the way it should?

Most high-CBD varieties promise relaxation but fall flat—either too weak, too slow, or just not flavorful enough to enjoy daily. You end up doubting whether the plant is working or if you’re doing something wrong.

Sweet Critical CBD flips the script: it’s a no-fuss, fast-finishing strain bred for consistency, big yields, and a deliciously sweet profile that actually delivers on calm without clouding your head. With a balanced Indica/Sativa structure and rock-solid genetics, it grows predictably whether you're in a tent or outdoors.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Sweet Critical CBD last summer in my greenhouse, and it was one of the smoothest runs I’ve had. I started with five seeds, all of which popped, and used LST to keep them under 1 m. The stretch during pre-flower was moderate, and by week three of flowering, the smell was already sweet and pungent. I ran a carbon filter the whole time—smart move. The buds packed on weight fast, and by day 58, they were rock-hard and glistening. I flushed for nine days, dried slowly, and cured for three weeks. The result? A clean, smooth smoke with a flavor that’s both fruity and earthy. Perfect for unwinding without zoning out. If you want a reliable, high-CBD strain that actually delivers, this is it.
