There are a number of ways to answer such a open ended question. For starters, how precisely do you define strength? If strength is simply the THC content, the infamous G-13 has been documented at a incredible 27.2% THC. Authorities such as Jason King, author of the Cannibible series, claims that Heroauna..a cross of Northern Lights x Hash Plant is even stronger than G-13. His estimates put it at a minimum of 25% but probably stronger. Mako Haze from Kiwiseeds tested at 19.7% in 2005. Contrary to popular belief, it is not only indica based strains producing prodigious THC content. Mako is a 75sativa/25indica strain. Arjans Ultra Haze #2 is another sativa dominant strain with a high THC content. Testing at over 20%, it produces a very strong, fast, trippy high with a balanced body hum.
Whenever analyzing the potency of a strain, it is of paramount importance to remember that gland or trichome production is not always an indicator of the THC content. Some strains can be completely frosted with glandular formations and result in only a killer headache. Three main trichome forms are found on bud, but only the capitate stalked glands contain the desired psychoactive Delta-9 THC cannabinoids. Another variable to consider when quantifying strength is precisely when the herb is harvested. Harvested too soon, glands may have yet to produce the Delta 9 all smokers yearn for. Harvested too late, the Delta 9 can degrade into non psychoactive cannabinoids and produce no effects at all. When judging the quality of bud, THC content is but one of many characteristics that should be evaluated before assigning a grade. Taste, aroma, burning qualities and of course the nature of the high all critical areas from which to judge a strain.
