Grape Blow is a hybrid.
Public lab results give a good picture of its strength: 16 flower samples tested between 2021 and 2022 came in at a median of 22.9% total THC (the middle half ranged from 22.3% to 23.5%). That is in line with most flower on Canadian shelves. Potency varies by grower and batch, so always check the label.
