Ok in week 9, going to need a few more weeks but no worries as I am enjoying watching these buds get fatter and denser every day. Can’t wait to try some other seeds from crop king

Bought 5 Jack Herer AF seeds. Recv’d 7 (Thanks for the freebies!) in 4 days. I am in Wisconsin. I grew 2 at a time. 6 of 7 germed. All were grown indoors, 2 gallon pots, Fox Farms Ocean Forest or Happy Frog soil. No nutes, store bought generic bottled spring water. Lighting was LED Viparspectra 450. Grows and harvest were consistent for all. They all got about 18 inches high. About 4 weeks to flower. Chopped at about 9 weeks. Dried yield was between 15 and 20 grams per plant, not the densest buds, but also not the lightest. Pretty much in the middle. Very nice smell and taste. Good potency, again, pretty much in the middle. Buzz is good for daytime, uplifting and energizing.Very happy with my results. I would recommend. I have since grown (or growing) CKS Lamb’s Breath AF and White Widow AF. I will post reviews on them.

This is my first time growing Jack Herer from Crop KIng seeds – I have grown Jack from seeds from other companies. In fact I started growing my own herb in 1975. The good – my 5 seedings have been in the ground for 4 weeks now (Fox Farms soil augmented with local work castings – I have been using this blend for the past five years and it works for me. I grow outdoors here in the SE US. My seedlings are growing nicely and are stocky little guys. You can see the Ruderalis in the leaves and I have passed them off as “other herbs” to folks not familiar with what auto flower plants look like. All in all I am quite pleased with these plants. On the other hand only 5 out of 10 germinated. I contacted Crop King and they called me back promptly. I missed their call and gave them a call back – very nice and easy. After discussion with someone who seemed knowledgeable I was promised that I would be sent 5 more seeds within 10 days. Its 4 weeks later and even with the Covid other stuff comes to us – albeit a bit more slowly. So three stars based on germination and not receiving seeds (the initial packet contained exactly 10 as ordered). I have space for 10 auto flowers or 4 regular feminized indica – so I filled my extra space with five White Widow auto flower but that’s another story.
