I have an indoor growroom and in my recent harvest I found seeds in the buds, but I’m sure there are no male plants in the room. I’ve heard that light leakage can cause plants to become hermaphrodites. Is this true, and if so, do you have any tips for avoiding this?
It is fairly easy to spot the difference in buds as the plants mature. That is also why it is generally a good idea to grow more than one plant – even the first time. Observation, practice and patience are the keys to a good and healthy grow. Feminized seeds produce femal plants 99% of time, and should one turn hemaphrodite, simply take care to remove it.
However, this tendency is also considered to be a sign of inferior plants. A good mother plant will not show signs of hermaphroditism even when subjected to this kind of stress. All cannabis can turn, but high-quality genetics will resist the urge the most.
WHAT TO LOOK FOR
Female plants take a bit longer than males to show signs of gender after flowering. The plants begin to develop a few wispy white hairs where the buds will soon grow. These flowers begin to form between the stalk and stem. Female pistils are always white (never green).
However, since this is a problem that will not disappear during the growing process, here are some guidelines for checking your grow.
Finding a hermaphrodite in your growroom can happen at any stage of the flowering cycle and is indicated by the presence of male flowers growing on the same plant as female flowers. As with all species in nature this can occur in varying degrees. A plant can become slightly or majorly hermaphroditic. In cases where singular male flowers are found between the branch and stalk nodes, you should be diligently removing them as they grow. You must re-inspect the plant top to bottom every few days to be sure pollination and seeding doesn’t occur. If you find male flowers (anthers) actually growing from within the female flowers (buds) the situation is a little more dire. You can still remove all the male anatomy as it appears, but it will be harder to find and much more prevalent. This is a horrible discovery that leads to a tough decision: Should you let the plant live and risk the whole crop being ruined by seeds?
There are other environmental factors which can stress a plant into a sex conversion. This includes as a reaction to insects or disease. It can also occur with the use or overuse of certain kinds of pesticides and fungicides.
First up, weeds already going to seed or getting close. Catch them now before seeds disperse!
If you’ve made it outside on a recent sunny day, you’ve probably noticed the abundance of flowers blooming in gardens, parks, forests, and throughout King County right now. Unfortunately, the noxious weeds are out there, too—many of them bolting, flowering, and even going to seed already.
Many garlic mustard plants in King County are going to seed. Note the long, skinny seed pods on this one.
Below are some of the top regulated noxious weeds to keep an eye out for this month. Please let us know if you see one of these high-priority invasive plants, so we can make sure they’re controlled or eradicated in time!

1. Top priority: eradicate before seeds disperse
Garlic mustard (Alliaria petiolata), a Class A noxious weed, is a biennial or winter annual herb, can self-pollinate to produce 62,000 seeds and overtake a relatively undisturbed forest understory. Eradicating it before seeds mature is key. You can identify garlic mustard by:
