- WHY USE BIOPHARM’S FEM MAGIC: By using Biopharm’s Fem Magic, you can make female seeds of your favorite strain with 99% accuracy. Our two-part kit is proudly made in our own USA lab. We want you to be completely satisfied with your purchase and are happy to provide our own customer support to resolve any issues you may have.
- HOW TO APPLY: Choose a plant that has not started flowering and is at least 2 weeks in the vegetative cycle. Spray one entire plant (not just the foliage) once a day for 14 days. Before the pollen sacs open, put a collection device under the feminized plant to catch the falling pollen; use this pollen to dust another plant in flowering mode. (Alternate method: Put a fan near the feminized plant and place a non-feminized plant nearby so the pollen can transfer to the second plant.)
- PRESERVATION: Biopharm’s Fem Magic allows you to preserve your favorite strain of the sacred plant. This allows you to save a lot of money by not buying female seeds from the big growers.
- FEMINIZED SEEDS 99%: Take the guesswork out of it! Biopharm’s Fem Magic is the most reliable method for producing feminized seeds of dioecious plants. One kit is all you need to feminize an entire plant to produce female pollen. When the pollen from your feminized plant is transferred to the flowers of your non-feminized plant, it will produce female seeds with 99% accuracy.

- Canna-Fem Reversal Spray enables growers to create feminized seeds.
- Growers are able to keep the strains they love without having to keep mother plants or they can produce their own genetics.
- Using our Reversal Spray does not cause more hermaphroditism within the plant.

Reversing the plant from female to male is only temporary and does not alter the DNA of the plant in anyway.
