Nearly all Sensi Seeds Indica and mostly-Indica varieties fall into the fast/heavy/compact category, with certain strains being particularly good performers.
Big Bud®and Fruity Juice (Indica/Sativa) would be two of our heaviest yielding varieties with a flowering time of 10 weeks or less.
However, the faster, slightly lower yielding varieties such as Northern Lights, the various Skunk strains, Maple Leaf Indica and other Afghan cannabis strains may prove to be better producers over time. This is because their 7 to 8 week flowering period could allow a whole extra harvest per year.
