A flush of healthy white stigmas is the sign of a happy cannabis plant.
Stigmas are the white, dental floss-like structures that protrude from the female flower.
These stigmas act as pollen catchers in nature, but for sinsemilla growers, they're pure gold.
In the absence of pollination, cannabis flowers will continue to produce more and more stigmas which create the bulk of the cannabis flower that we consume.
For a typical 8-week flowering crop, stigma production is most vigorous during weeks three to six.
Brown or dry stigmas can be a sign that the plants are going too dry or they've been sprayed with a pest control product.
Early and vigorous white stigma production is a good sign!
