Opus tests each seed lot for germination percentage, feminization rate, and potency testing of the actual prodigy seed. We also offer experimental seed to those who want to share with us in our data collection of new strains. We report what we know about strains as we become aware of it.
Buyer beware! All seeds are to be considered experimental, and have no written or implied warranty. All sales are final, as-is, and where-is, with positively zero chance of a refund. If you have trouble with your seeds, please let us know and we will look into it. If we discover a problem with the seeds, we may choose to offer replacement seeds...strictly at our sole discretion.
We at Opus Seed Bank work hard to create excellent genetics, and we are honest about potential issues that we may discover about our prodigy seeds. “Issues” are almost always a result of pollen contamination somewhere along the line. Even though we are careful and methodical in our breeding practices to create pure feminized seed having desirable and predictable traits, nature still seems to find ways to spread diversity.
We list our seeds as “feminized” if our growout trials have fewer than 1 male per 100 seeds (99%+ female). In actuality, we typically get less than 1 male per 1K seeds, and occasionally less than 1 male per 10K seeds. Even so, we produce many millions of seeds annually, and we have discovered that some clients report variations in percentage of feminization. Regardless of feminization rate, all cannabis farmers who wish to grow seedless crops must create and enforce a “male patrol” program. Males must be discovered and carefully destroyed before pollen sacs open. We have seen pollen sacs form and release pollen in only a few days. Ideally, every plant should be inspected for pollen sacs every day. In practice, we have achieved seedless crops from careful inspection twice per week from the first sign of flower and continuing until every plant has been verified to exhibit female pistils. It is possible for female plants to produce pollen sacs and viable pollen. This behavior is called hermaphroditism, and is typically a result of plant stresses such as irregular light cycles, irregular watering, nutrient deficiency, temperature extremes, and/or the presence of anything that inhibits ethylene in the water, soil, or overspray (soluble silver, for instance). Hermaphroditism is also a genetic trait, and seeds created from hermaphrodite pollen are predisposed to herm again. Seeds found in sinsemilla bud, aka “bag seed”, are commonly herm seed and should not be grown in commercial settings or where pollen drift could damage yours or your neighbors crop.
That being said, all feminized seed is hermaphroditic seed, created by coercing a female plant to produce pollen that is used to pollinate the natural female recipient plants. Opus Seed Bank uses an ethylene inhibitor to create these hermie pollen donors, rather than stressing a plant into hermie conditions. This mechanical interference is not genetic or stress related, and therefore mechanically induced female pollen does not pass on any genetic hermaphroditic predisposition. This intel is critically important that you know, understand, and verify when choosing your commercial seed supplier. More often than you might think, seed producers do not know or understand this, and unfortunately there is plenty of misinformation on the internet about feminized seed. We know of a farmer in Oregon who planted a large outdoor crop of hemp using a residential well, without irrigation rights. Midway through the season, a neighbor complained to the water district and the authorities capped the farmer’s well. The crop suffered dehydration, and this stress caused a number of herm pollen sacs to form. The herm pollen sacs were left unchecked, and the drift of pollen created a bumper crop of herm seed in the farmer’s field, as well as contaminating his commercial cannabis neighbors for miles around. The farmer should have disced his crop the same day the well went dry, but he didn’t. Instead, he harvested the seed and sold it as “feminized” commercial hemp seed, at a time when hemp seed was in very high demand. Rumor has it that 19M seeds were sold at a dollar each, and of course the seed buyers unknowingly planted herm seed the following season, the crops of which went herm again and brought more havoc and loss to their neighbors. The original crop may have been good.
Contaminate pollen can come from hemp plants or marijuana plants, and from either male and hermaphrodite female plants. All males that occur from feminized seed production are the result of pollen contamination, and for every male there is an equal or greater number of females that possess the contaminate genes and will likely grow to full maturity having never been
