From 420 Genetics - Matanuska Thunder from Brother's Grimm grew some huge size rock hard buds with many girls snapping due to the great weight and size. I myself found Matanuska Thunder to be very mould resistant compared to other strains with a terrific smooth high and a intensely skunky smell and flavor. Of around 30 females only one was used for this cross and this particular MTF clone produced a strong trait of purple not a result of cold temps. As you know both these strains are known for their legendary highs and above average yields and by crossing A-11 into MTF has lowered the flowering time to around the 7 week mark and still keeping that awesome high that many of us love. Great for the indoor cultivators wanting great yields and highs. This cross is just another lot of dense resinous buds that produces magical highs.
