Feminized seeds
Feminine recipe
Dutch Passion's feminizer testing program revealed that grow room factors can be manipulated to produce better female to male ratios. The female-inducing recipe, to be implemented during the first month of growth, involves providing: 1) more nitrogen, less potassium; 2) more halide (blue spectrum) and less high pressure sodium (red spectrum) lighting; 3) shorter light cycles; 4) a grow medium of 6.6 to 6.8 pH; 5) lower temperatures and higher humidity, plus higher soil moisture; 6) minimized stress (cloning and other stressors can destabilize plants, causing them to go male or hermaphrodite).
Henk is constantly running experiments to fine-tune his feminizer technology. He removed Purple Star from his feminized line because of poor results. Some feminized varieties produce between 80 and 90% females rather than 100%, and a few hermaphrodites have occurred in isolated test crops. Henk has found that Green Spirit, Mazar, Masterkush, Oasis, Blueberry, Buddha, Voodoo, Purple #1 and Trance are the most reliable feminized seeds; he's working to increase the range and dependability of Dutch Passion feminized offerings.
"The difference with Dutch Passion is that we are keeping the trust of our customers by making sure our seeds give them what they expect," Henk says. "We concentrate on ripeness, freshness, and size, and we strive to make strains grow out true. Our goal is to maximize the yield our customers get. I wish I had had Dutch Passion seed company to buy from when I was 18."
