Seedsman tribute to Jack Herer
Now almost as renowned as its namesake, Jack Herer is a classic strain that combines the cerebral euphoria of a Sativa while maintaining the heavy resin production of an Indica. Jack Herer was created in the Netherlands in the mid-1990s where it was later distributed by Dutch pharmacies as a recognized medical-grade strain. Since then, the strain has taken home numerous awards for its quality and potency. This strain can be grown anywhere but indoor growers should wait 50 to 70 days for Jack Herer to flower.

We have been growing for years. This is our first time purchasing seeds from Seedsman. Sadly, these seeds are not good. We planted one of the 10 packs of Jack Herer feminized seeds. Out of 10 seeds, we got only 2 sprouts and one died. We have primarily grown from seeds and are experienced growers. We have another brand of seeds that we planted and all 10 are up and doing great. Very dissatisfied with these Serdsman Jack Herer Seeds.
