Time failed us to test this hybrid, but all our Creeper hybrids so far have been of a high quality. Considering the traits of the Creeper and the Afghani 1, this strain must be top quality. Should be a powerful indoor strain. Because we have not smoked it ourselves yet, the price is kept low for the being.
