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.

Thanks for your review. We do test seeds from all the batches of seeds that we sell - and only release for sale seeds that test over 95% germination - we are therefore very confident with the quality of the seeds that we sell. We also hold our suppliers to the same high standards. This said these are live products and competencies & environments vary so we try to help customers if they have issues. Please reach out to our customer service team at [email protected] to see what they can do to help, and check on our blog for our recommended germination techniques. Best Seedsman
