    Fantastic seeds bank with great employees and very reliable. Their promises are kept. Great cross of the famous Jack herer and Critical with a pretty short flowering time and some serious yields. Even with my little experience i managed to grow almost 0.7 Ibs. Taste and effect are really good

    Although I don’t have much breeding experience, I haven’t experienced any problems. I have applied a growth phase of 3.5 weeks and finally let the plants bloom for 8.5 weeks. With a result of just under 400 grams per m2, I am absolutely satisfied

    This is my 3th time i’m growing critical jack. Just love this strain. Such a nice structure and creazy buds. The effect is just amazing as the plant. Very intense on the mind but balanced. Recommend for growers who like a strong weed.

    No problems with germination. However, one plant died in the growing phase. The others are in week 3 of flowering now. Nice small buds so far, but i still have a long way to go.
