M31
A special Indica Indoor hybrid. Very suitable for commercial indoor growing when making use of the plantlet method. Pick out the plants you like the best and reproduce. Heavy yields of extremely resinous buds. The buds are, due to their structure and the amount of resin on them, weighting very heavy. Small, compact plants. You can easily grow 4 crops a year indoors. Experienced growers can yield 1500-2000 grams per square meter per year. Two people could not finish a joint. The plant on the picture has been taken outdoors after flowering was inducted indoors. The plant turned purple because of a very cold fall. Williams Wonder can't be grown outdoors without being inducted to flower artificially previously.
