Info "Feminized Seeds"
In an experiment done in 1999 we grew 15 varieties of "feminized" seeds. We started with 30 seeds per variety. The goals were: 1) to determine the percentages of female, male, and hermaphroditic plants. 2) to compare the uniformity (homogeneity) among plants from "feminized" seeds with those grown from "regular" seeds.

1. The results were excellent. Nine out of fifteen varieties had 100% female offspring. Percentages of female plants from the other 6 varieties were between 80 and 90%. These plants were all hermaphrodites, producing their male flowers at the end of their lifecycle. Seed-setting hardly took place. No males were found.
2. Approximately 70% of the plants of varieties grown from "feminized" seeds were far more uniform than plants grown from "regular" seeds of the same variety. About 20% of the varieties were a little more uniform, while in 10% of the varieties no difference in uniformity was seen.
From literature and our own findings it appears that the growth of a male or female plant from seed, except for the predisposition in the gender chromosomes, also depends on various environmental factors. The environmental factors that influence gender are:
a higher nitrogen concentration will give more females.
a higher potassium concentration will give more males.
a higher humidity will give more females.
a lower temperature will give more females.
more blue light will give more females.
Fewer hours of light will give more females. It is important to start these changes at the three-pairs-of-leaves stage and continue for two or three weeks, before reverting to standard conditions.
To produce our feminized seeds, we start with selected female clones. Under standard conditions these female clones do not produce any male flowers. By the method we found, we are able to have these female clones produce abundant male flowers and pollen. The pollen thus produced we use for the production of our "feminized" seeds.
Below you will find the varieties Feminised Cannabis Seeds. All varieties below are in stock.

Ultra Skunk

In our Swiss experiment, we flowered several Dutch and Swiss Skunk
clones and several Skunk seed varieties. The goal was to select
the best possible Skunk. By hybridizing the best two Skunks,
we created Ultra Skunk, a very homogenous variety. Thick buds with
beautiful wooly pistils. The taste is sweet, soft and fruity.
The resulting high is up, soft but lasting.

We only produce this variety in its feminized form.
In this way the connoisseur is guaranteed absolutely premium
Sativa seeds. This variety has been selected from Seed Bank
genetics. A female mother plant was chosen from among 50 female
plants grown from seed. After cloning this female, different
clones were treated to produce abundant female pollen.
By fertilizing other clones (backcrossing), feminized seeds were
produced. Growing marijuana seeds in this way guarantees offspring that are
far more homogenous and powerful than offspring from seeds produced
in the regular manner. Mostly Sativa, with a clear Haze influence.
First class high. Branches bow down at the end of the lifecycle
of the plant, due to the weight of the buds.

Flowering period: 9 weeks

Green Spirit

Green Spirit is a hybrid of Big Bud and Skunk #1.
We made this hybrid because Big Bud itself is not a
very consistent strain, with very big differences among
individual plants. By crossing Big Bud and Skunk #1,
Green Spirit became quite homogeneous. Good results under
artificial lights. Clear and strong high. The plants have
an explosive flowering and are extremely resinous. Very high yield.
THC = 5.9%, CBD < 0.1%

and yield of the famous Northern Lights #5. Hybridized with the
best of our potent 100% Haze genetics. This variety has a solid,
strong long lasting "high", combined with a well balanced, soft
smoking experience. Good for bumper harvests. A perfect variety

Original Flo is a Sativa/Indica cross (60% Sativa/ 40% Indica)
with very Sativa-phenotypic characteristics that also matures
very early. The large, tight, spear-shaped buds are made up of
small, densely packed purple calyxes. The plants are taller and
like to branch out. Indoors the buds are fully mature by the end
of their sixth week. "Flo" is ideal for greenhouse production.
The motivational "high" produced by "Flo" is quite unique; the
flavor is like Nepalese Temple Hash. A most pleasant and enjoyable

This is an upgraded strain of our valued former Afghan/Skunk.

and we managed to improve on yield. The Afghani (Mazar-i-Shariff)
part is a very short Christmas tree-like plant, 100% Indica and
very resinous. The F1-cross with Skunk #1 gives the variety a
bigger yield and better taste. Very good "up" high. As both parents
are very consistent, the offspring are very consistent too.
