Though this plant is relatively easy to grow, it requires a lot of headroom for its crazy height. Flowering in about two months, it produces a moderate harvest. Combining genetics from parent strains Skunk #1 and the Afghani landrace indica, Green Crack can have soaring levels of THC that reach into the over-20% realm. This makes it unsuitable for novices, but veterans may have fun testing their tolerance limits. Effects include bursts of energy, a skyrocketing of the mind into the ether, increased feelings of optimism and positivity, and a focusing of mental clarity.
