Jack Flash #5 seeds from Sensi Seeds originate from a cross of Jack Herer x Super Skunk x Haze, making it slightly Sativa dominant (65%), so the all round characteristics of the plant and strain are top-notch. The plant itself, a powerhouse of bud production, after a relatively short flowering time (for a Sativa hybrid) of around 55-75 days you can be looking up to 450-500g/m2 indoors, and 600-800g/plant outside. (Outside planting should coincide with the seasons – so looking to harvest this bad boy in the Northern hemisphere should be expected around October/Early-November – Southern hemisphere : April/ Early-May).

It has about 18% THC and a delicious effect – It’s a really good one to smoke with friends; you’ll be laughing before even having told the joke. The effects are part cerebral – part physical, so you can be happy and in a great mood all whilst chilling out and relaxing.

The smell is that of a woody Hazey Incense.
