Meican HazeNorthern LightsSkunk #1
One of Nirvana's all-time favourite marijuana seeds.
Nirvana Jock Horror is a three-way marijuana hybrid of Northern Light, Skunk and Haze. Jock Horror produces so much resin that even its branches glisten with THC glands. This marijuana seeds variety has a unique fresh flavour and packs a strong "up" buzz. Jock cannabis seeds will finish flowering earlier than the original Jack Herrer of a few years ago. This cannabis strais is definitely one of Nirvana's all-time favourite marijuana seeds.

Got seeds of JH two years back. Collected seeds from two more Indica phenotypes and now have had six grows with excellent results. Have had a mostly sativa looking phenotype that was way strong and good. The indica phenos have produced good with sweet vapor. Nirvana's Jock Horror impresses.

I got 5 beans via stealth delivery. All 5 popped and grew to flower. Used FF Ocean Forest and Plagron nutriens for veg and bloom. Had the room under 2 - 450 HPS/MH (will double tha.t next time) . Grew absolutely AMAZING pot. Went 8 weeks Veg and 8.5 weeks flower and got 420 grams from the 5 J.H. ladies. It's smell and taste are unique and sweet. The high is VERY strong and lasts. Will reorder for sure

These are the best I've had. The WW is doing really good but the Jock Horror Feminized from Nirvana are amazing. Highly recommended by me. About 3 to 4 weeks from harvest and these ladies are monsters. Trichs are starting to get milky in a very few spots. Smell is unbelievable

This is a good version of Jack Herer - not the best, but good.

Jock Horror Feminised Seeds - 5
This one grew to about 2 metres tall in my grow tent and took over the entire thing with about 15 beautiful colas branching out all about 1 meter long all glistening with sticky oil. Perfect for DWC, she flowered for 9 weeks until i could hold off ripping it any longer. Great smoke for sitting back at home & tended to make me sleepy especially at night time after smoking a few after dinner.
