A strain that made its first appearance in the 1970s or 1980s, William's Wonder (or Willy's Wonder), has since only continued to gain popularity as one of many purported legendary strains.

The story may have started with Sacred Seeds and Sam the Skunkman back in the 1970s but no one seems 100 percent certain. The 1987 - 1988 catalog by the SSSC breeders was the first public appearance of the strain and they did acquire a lot of stock from Sacred Seeds prior to that. It's exact genetics are still unknown but most believe it to be descended from landrace Afghanistan Indicas. Designed to be grown only indoors with ease, William's Wonder quickly became a favorite to growers of the time.

Creeping on users, the effects of this strain are certainly Indica-based as they grab hold of users in a pain numbing and euphoric hug that usually does not end until users are lulled to sleep. Some users experience a foggy fatigued feeling the following morning and others feel dizzy while using William's Wonder. Effects can easily last over two hours and may assist patients in alleviating insomnia, inflammation, depression, PTSD, anxiety and anorexia.

As it was developed for the indoors, to get it to flower the strain must be kept indoors throughout the growing cycle. However, it may be taken outside upon flowering completely. Unfortunately, this strain has since become very hard to come by but that has not stopped other breeders from trying to fill the gap with their own crosses and in-bred lines.

According to tests preformed by grower, Alaska Precision, William's Wonder can hit a THC high of 21.20% with a 4.3% terpene profile. 

This strain can take between 65 and 75 days to finish flowering. It supposedly has immense yields, SSSC claims that if grown under the right conditions that William's Wonder could produce an unbelievable harvest weighing between 1500 and 2000 grams per square meter.
