About Jack Herer

Sensi Seeds put this together in Amsterdam in the nineties and named it after Jack Herer, the legalisation campaigner who spent decades making the case long before there was any momentum behind it. The genetics are Shiva Skunk, Northern Lights #5 and Haze, landing at roughly 55% sativa, and the effect follows that side: quick, bright and chatty, a daytime jar rather than an evening one, averaging around 23% THC. The smell is the giveaway, wet earth and damp woodland with pine that jumps out when you crack a bud open. As a grow she close to runs herself, and the main thing to plan for is headroom, since she will push to around two meters. Nine weeks or so in flower, up to 18oz per square meter, and outdoors aim to chop by the end of September.
