North ThunderfuckRuderalis
Potent and productive auto strain.
North Thunderfuck Auto is an indica/sativa hybrid auto-flowering strain (Sativa 45%, Indica 50%, Ruderalis 5%) that results from crossing North Thunderfuck with a ruderalis strain. It's a potent auto with high yields.
This is a medium-sized variety with indoor-grown plants reaching a height of 70 - 140 cm. tall while those cultivated outdoors grow a little taller at 120 - 150 cm. Plants are ready to harvest in 10 - 12 weeks from germination with flowering beginning sometime in the third week or so of growth. Indoor yields are very good at between 500 - 550 gr/m2 while outdoors each plant can produce 90 - 140 gr. each.
After drying and curing flavours are earthy, lime and Skunk. THC is very high at 22%, CBD is low, and the effect is said to be physically relaxing and cerebrally uplifting.
