  1. Hi I ordered the Jack fem seeds from you and they are top notch so far! I was wondering if a scrog is the best option for growing them. I’m 2 weeks till flower and I just topped them 5 days ago.

  2. Close to harvesting the second year of Jack H I’ve grown. It’s TOTALLY true what the grow guide says: It grows easily, fast, and in the right fall conditions (I grow outdoors) begins flowering in mid August. I’m about 46 days into the flowering, and am looking at a bunch of cold, wet, weather for the end of the week. Worried about bud rot.

    Otherwise, regarding the strain affects, everything written here is tRUE. Totally true. It’s a highly creative high, slightly energetic (I usually smoke some before mowing the lawn or shoveling snow!), and just, well…fun. I’m a pretty happy guy by default, but generally get happier and funnier with Jack H in effect! Enjoy it. It’s great.

    Oh, and yes, I’m looking at more than a full POUND from my plant. Just tons of weed. It’s insane.

  6. I am growing a jack herer clone I bought legally in Oregon. I have it in a seven gallon pot for now bit plan on transplanting into the ground outside. I hope it turns into a monster.

  7. Gosh, I’m so sorry to say I haven’t had luck with your company or team getting back with me. Since my 1st and only batch of WW’s didn’t make it, and I never received any replacements, I am sure wondering what happened to them. This has been many many months now. please reply, again.

  8. Its like you learn my thoughts! You seem to know a lot about this, like you wrote the guide in it or soinhtmeg. I think that you simply can do with some % to power the message house a little bit, however instead of that, this is excellent blog. A great read. I’ll certainly be back.

  9. I orderd seeds and fertilizer. The fertilizer came in just a few days. The seeds to just under two weeks. Everything arrived as promised. Customer service is excellent. The company will email you within about 24 hours if you have questions. The seeds look healthy and I am excited to see how they grow. I am pleased with my purchase and am especially pleased to find Jack Herer seeds at a reasonable price.

  10. I got the 3 bottles of grow juice. Thanks. But someone forgot to put the seeds in the box. There was only 3 bottles and some bubble wrap. Unless I was mistaken about the seeds being shipped in this order.
    Thanks William


  12. I have lost seeds to Customs twice, and I’m afraid of name recognition. Although my Brother, that lives near me, has had no trouble in receiving seeds. Advice appreciated. Thank You, Lynwood
