Subcool Seeds/TGA Genetics created Quantum Kush from Sweet Irish Kush and Timewreck, according to seed bank Pevgrow, and wound up with a strain offering a sweet, woodsy taste and aroma. As Pevgrow puts it, Quantum Kush has very high THC, CBG, and THCV.

The strain is mostly indica, but with long, leggy plants that flower in seven to eight weeks. Quantum Kush is a prolific producer that grows tall inside or outside, according to Pevgrow. The seed bank says this strain tends to produce potent, long-lasting effects that include relaxation, appetite stimulation, and pain relief.
