It is perfectly feasible to cultivate Grail Widow indoors although the longest-flowering pheno-types make such an undertaking rather less viable. Approximately 70% of plants will finish in 12 weeks with the remaining Haze-dominant plants taking up to 15 weeks. Yields are between 500 – 750 gr/m2.
THC levels will be in the range 18 – 24% depending on pheno. with 1% CBD and CBG. Expect a wide range of scents, flavours and effects due to the genetic range of the parent strains.
