The producer of this Great Cannabis Seed has listed the preferred environment as Indoor;Outdoor Environments. The strength of Silver Jack cannot be reliably determined at this time as the information has not been released by the breeder and the information that is available from the producer of this fine Cannabis Seed lists it as being an average yielder. Seedmakers Seeds have not yet released reliable information as to the indoor height for this strain and while it is not always possible to easily characterise the Genetics of a Cannabis Seed with simple tags, the Cannabis Seed Keywords which would best accompany Silver Jack are: Hybrid. Seedmakers Seeds have their entire selection of Quality Cannabis Seeds available for purchase at Steathy Seeds this April! Silver Jack has been described by the breeder as having a Medium (56 to 90 days) Indoor Flowering Time and no Optimal Outdoor Harvest Time information is available.
