It sounds like you have a great lineup of strains for your grow, and adding a strain with naturally occurring purple flowers can contribute to a visually appealing and diverse harvest. Here are a few strains known for their tendency to produce purple colors:
Granddaddy Purple:
This is a classic indica strain known for its deep purple hues and sweet, grape-like aroma. It's a popular choice for those seeking a relaxing and calming effect.
Purple Haze:
A well-known sativa strain that gained fame in the 1960s, Purple Haze is characterized by its vibrant purple buds and uplifting, energetic effects.
Blue Mystic:
This is an indica-dominant strain that often exhibits blue and purple hues during flowering. It has a mellow, relaxing effect and is known for its fruity flavor.
Purple Urkle:
Another indica strain, Purple Urkle, is recognized for its grape-like flavor and deep purple coloration. It tends to induce a calming and sedative effect.
Blueberry:
While primarily known for its blueberry flavor, certain phenotypes of Blueberry can display purple colors during flowering. It's an indica-dominant strain with a sweet and fruity profile.
Remember that environmental factors such as temperature fluctuations, especially cooler temperatures during the flowering stage, can enhance the development of purple colors in cannabis plants. Using a product like Purpinator can potentially intensify the purple hues.
When selecting a strain, consider factors such as growth characteristics, flowering time, and the effects you're seeking. Also, check with the seed bank or breeder for information on the strain's potential to display purple colors and any specific recommendations for bringing out those colors.
