White Widow (South Indian IndicaBrazilian Sativa)The One (ThaiAfghani)
A longer flowering is compensated by a euphoric and relaxing effect.
Sketch is a cross of White Widow and another strain known as The One. It is slightly sativa-dominant and has a somewhat longer than average flowering time although it is very easy to grow for those with patience to wait a little while longer.
Sketch grows to be 120 - 150 cm. tall indoors with expected yields of 400 - 500 gr/m2 in a 9 - 11 week flowering phase. Outdoors plants grow a little taller at 150 - 250 cm. and producing 400 - 500 gr. each.
THC is high at around 20% with just 0.2% CBD. This strain's effect is happy and relaxed with an uplifting and euphoric note.
