Personal Experience of Pevgrow’s CEO (Alan)

When the team at Fast Buds told me they were crossing Frostbanger with Atlas Seed's Mendo Breath, I knew we were in for something special. I popped a few of these Mendo Frost Auto seeds in my personal 1.20 m (3.94 ft) tent, and the hybrid vigor was obvious from week two. They exploded in growth, and by the time flowering kicked in, the resin production was absolutely out of control. It literally looked like someone had dumped powdered sugar all over the canopy.

I kept my light cycle at 20/4 and fed them moderately, as they didn't seem to need heavy nutrient doses to thrive. The smell in late flower is intensely gassy with a sweet, creamy backend that makes your mouth water. I highly recommend running a fresh carbon filter because these girls reek in the best way possible.

After a slow dry and a solid cure, the smoke is incredibly smooth but hits like a freight train. It’s my new go-to for evening relaxation. If you love making hash or rosin, this is a must-have in your garden. The return on extraction is phenomenal, and the bag appeal of the raw flower is easily a 10/10.
