Silver Jack feminized seeds

Silver Jack feminized seedsAs the name suggests, Silver Jack is a cross of Super Silver Haze and Jack Herer.

Silver Jack feminized is a very stable strain which can be grown indoors or outdoors with hefty yields.

As a Sativa-dominant strain, Silver Jack feminized seeds grow into tallish plants with long fine leaves. They consume more nutrients than other strains so extra fertilizer is a good idea.

The flowering period is 9-11 weeks so it’s better grown indoors if you’re up north as you may struggle to get a harvest in before the temperature drops.

And Silver Jack is definitely one you don’t want to rush because it’s in the last three weeks that the buds will become thickly coated in sticky frosty resin.

As for smoking, Silver Jack is a truly lovely smoke with a spicy lemon flavour and a sweet aroma. Silver Jack is high in THC and gives a strong, long-lasting high which will give you a creative and energetic boost.

As such, Silver Jack is a good daytime smoke, and is also helpful for sufferers of anxiety, ADD, ADHD.

Silver Jack feminized seeds are thus an excellent choice for Haze lovers and medical growers alike.
