Strain reviews for Jack Herer

Seeds arrived quickly, and the first two I planted came right up. Currently, they are growing nicely. I cannot comment on quality until after harvest.



Popped 5, but only one made it past 4 days. I got replacements for next time. The one that made it is healthy and already in full flower by week 4 and pushing 2 plus feet from the soil. I need to do some more training, but it already has 12-14 tops reaching for the light! Keeping my ph at 6.4-6.7 close to 6.5. She has about 6 and a half weeks to go, and I’ll update on dry yield once I’m done. I’m really happy with the outcome so far.



You want to talk about a seed genetics that is gonna blow your mind for an auto, check this stream out you will be amazed what this thing does. Be ready for big collars and fast vigorous growth guys.



I have not had some good Jack in a long time and took to ordering some as a first grow in a long time. It turned out superb. I personally loved it, and more so after my most veteran friends who grow gave it a grade “f*****g A+” I quote. After a few months curing, it is even more amazing.



I haven’t had one of these that hasn’t left a smile on my face. Full thick grow every time.



Would 10/10 recommend this strain to grow to anyone! This was my FIRST EVER photoperiod grow, and she was a seriously amazing plant to work with. She was quite the yielder too! Pulling 184.1 Grams dried / cured / trimmed in 105 days seed to harvest.
