Critical # 47, from Positronics, comes from a hybridization between Critical Mass and AK 47, two of the sweetest marijuana strains on the market. Plant size is medium-high, very branched. You can prolong the growing period due to its quick flowering, as well as using this strain for SCROG setups. Its aroma is strong, reminding mangos and peaches with vanilla undertones. Its effect is relaxing...and will open your appetite! Awarded with Second Best Indica prize at 2013 Expogrow.
