Strongest Seeds Available?

What plant produces the most potent smoke? (if correctly grown).

Around here we don't get much of a selection, the only names I've heard around my area are "Big Bud", "Cheese" and "Bubblegum".

Cheese being the most expensive. £170 and Oz.

white widow, indica pheno.

White Russian Serious Seeds, definitely a nice uniform plant to grow.


In an independent seed comparison in which over 150 different seed strains were grown out in a greenhouse, the White Russian came out as the strongest plant (22% THC, likely to be the strongest plant known at present!!).
