Jack Herer Sativa Hybrid (Canuk)

Hey everyone,

Just got my grobo! So excited. The wife and I just set it up and started our first grow. Jack Herer Auto feminized seed from Canuk seeds.

I noticed the grow time on the description from Canuk & the recipe list show 8-10 weeks finish time but the actual recipe grow time is like 124 days. Which one is correct?

Thanks for the help!

Make sure you choose the auto recipe. 124 days sounds correct for a photoperiod, not an auto. Happy growing!

Both seeds shown from Canuk on grobo’s recipe list show as photoperiod. I think the grobo recipe needs to be updated.

@J-Bird Probably best to go with a generic auto or ask grobo support for best advice


Hey @J-Bird,

Thanks for the poke, you have discovered an error in my recipe for sure, thanks! We currently do not have an Auto Jack Herer recipe so I agree with @DeeDub, generic auto is the best bet for you now.
