The I49 Seed Bank allows you to buy feminized cannabis seeds online. Our feminized marijuana seeds are perfect for your home grow show or commercial garden. Why waste all your time with male plants when all you want is that fruitful female plant? We have tried and tested suppliers that combine the latest feminizing technology with the traditional high-quality strain standards to deliver a truly superior feminized cannabis seed for sale. Whether you buy three seeds from us or three thousand seeds, we will take care to package your order in a discreet and delicate way so that you can get growing as soon as possible. Whether you grow indoor feminized seeds or outdoor feminized seeds, we know that time is of the essence. Order your feminized seeds today by telephone or email and your feminized plants can start their way to a fruitful future of cannabinoid manufacturing.

DO – Try Growing Outdoors. Even if you have a successful indoor grow room that is pumping out a regular crop of epic buds, there is a unique enjoyment that can be had growing outside. Whether it is a small single potted plant on your back porch, or a feminized blue dream plant to decorate your rose garden, the cannabis plant is a beautiful sight to behold and can add a fragrant twist to any small home garden.

Patchwork genetics produce a stimulating Sativa capable of skyrocketing thoughts and actions into the most spectacular of realms!

Other benefits of Feminized Seeds

Not extraterrestrial in origin, but out of this world just the same.

Feminized seeds are not the same as autoflowering seeds. Feminized seeds available on the website are all ‘photoperiod’ seeds, which means that they will require a change of light schedule to instruct the plant to switch from vegetative stage into the flowering stage. Plants can veg on 14 to 20 hours of continual daylight, but in order to flower this must be changed to a 12 light / 12 dark schedule. Outdoors, this can be achieved naturally with the passing of autumnal equinox (near the end of September). For some outdoor growers this is a little late to allow for adequate flowering time before winter, so if this is the case you will have to artificially shade your plants for a few hours and the beginning or ending of the day.

If you are growing indoors, consider the many options you have to shed light on your feminized cannabis seed plants. Different types of lights offer different benefits at different times. Some cost more than others and some run hot while others remain cool to the touch. These factors combined will also determine how high above your plants you need to be hanging your lights, so be prepared to be flexible throughout your grow as you learn and work out the bugs.

Buying Cannabis seeds should be a comfortable experience, and what could be more comfortable than sitting at your own couch or computer chair and taking your sweet time. No line-ups or having to find street parking. No pushy customers in line trying to sway your decision or biased bud tenders that have never grown weed themselves but just have their favorite handful of strains to smoke. When you purchase from home you can research the different strains that catch your eye and make sure you understand the basic requirements for successfully growing feminized seeds. You can buy our indoor variety of fem seeds if you plan to grow in a small room in your home, grow-tent, or commercial warehouse space. We also have great outdoor feminized seeds that can thrive in your garden or backyard greenhouse.

To complicate matters, in plants, a range of flowering responses to light exists. Plants can be short-day species (require days with short periods of light to flower, e.g., Cannabis, rice), long-day species (require days with long periods of light to flower, e.g., Arabidopsis, wheat) or day-neutral (flower irrespective of the light conditions, e.g., cultivated tomato, strawberry; Figure 2). To react to changes in day length with the initiation of flowering, the plant needs to be able to detect these changes, therefore the photoperiod pathway is at the centre of many studies.

From an evolutionary perspective ensuring appropriate flowering certifies the survival of the next generation. In an agricultural context, flowering time is directly related to yield, and the fine tuning of flowering is a major focus of crop improvement efforts. During crop domestication by humans, alterations in key flowering time genes were instrumental in adapting crops to different climatic conditions. The success and worldwide expansion of staple crops like wheat are partly attributed to variations in flowering time genes. During domestication and the artificial selection for specific flowering traits, such as altered flowering due to temperature insensitivity, cultivation was enabled at a wide range of latitudes and in different climates.

How do plants flower?

Innovation is booming in the Cannabis industry, with hemp now being used to produce bioplastics and microgreens for salads. But in contrast to other crop plants a huge knowledge gap exists for Cannabis, and our understanding of its genetics, physiology and development lags behind many other crops such as maize, rice or wheat.

As early as 1912 it was known that the photoperiod influences Cannabis flowering time. As a short-day plant, Cannabis flowering time is particularly affected by day length. Cannabis remains vegetative under long days and flowering is accelerated after several consecutive short days. Therefore, to cultivate Cannabis at northern latitudes (summer day lengths can be over 17 hours in northern Europe), early flowering phenotypes would be favourable to ensure ample flower and seed production as well as to allow sufficient time for seed ripening. On the other hand, to grow Cannabis for fibre, for which early flowering is not desirable, at southern latitudes with short days, late flowering phenotypes are required.
