The Purps only has 4 phenos. All very bright purple. Also, on a side note, the Purps is the only genotype that can change phenotypes when taking cuttings.
Explanation:
If you have only 1 Purps mother plant, and you take a cutting from it, it can change to a different pheno during veg, which is a cool phenomena which can be a plus in the end.
I know its hard to believe but Ive grown it long enough to understand it. Ive read about it in the MJ Strain Books.
Also: It is nanner sensitive. Try not to stress them out. It likes to throw nanners during the last few weeks of flower. They can be picked off with a wet paper towel to nullify pollin spreading and still be ok without cauzing any damage to the whole crop. Just be easy on them with the light schedules.
