Females will have a round structure with long hairs—these hairs will develop into pistils, which will catch pollen in the air.
There are a few indicators that will give you a sense of whether the seed is worth germinating.
As interest in CBD as a medicine has grown, many breeders have crossed high-CBD hemp with cannabis. These strains have little or no THC, 1:1 ratios of THC and CBD, or some have a high-THC content along with significant amounts of CBD (3% or more).

Cannabis seeds require three things to germinate: water, heat, and air. There are many methods to germinate seeds, but for the most common and simplest method, you will need:
Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.
As we’ve mentioned, cannabis is a dioecious plant, meaning male and female reproductive organs appear on different plants.
Once cannabis seeds are mature, the female plant begins to die, and seeds are either dropped to the ground where they grow into new cannabis plants next spring, or the seeds are harvested for processing into seed oil or food products, or stored so they can be sown in the ground later and become the next generation of plants.
Indoors humidity control is very important from seed to flower. Leaves aspirate atmospheric moisture as part of their day to day functions. Properly balanced humidity makes for a healthy pest and mould-free environment.
WATER: Like all living things cannabis needs water to grow, thrive and carry out its biological functions. If you live somewhere with regular rainfall your outdoor crop may get all it needs from nature alone. Large cannabis plants are notoriously thirsty. If you are going big then you will certainly need to supplement water between rains.
Step 3: Lights For Indoor Cannabis Growing
Your plants are happy in an organic soil or they are being fed nutrients designed for the vegetative phase. Lots of fan-forced breezes keep temperatures under control and strengthen your young plants. Exotic disciplines can be used like adding carbon dioxide to the environment. Low-stress training and scrogging can be used to increase the growth rate and flower potential of indoor cannabis.
Outdoors you need to pick your time. Know your particular climate well. Have a sun cycle app or chart to make sure you get your timing right. Too early and you risk your plants going into flower immediately, then re-vegging when the daylight increases. This is unwanted. Your flowers will not form properly when blooming begins. Too late and you will have small plants with fewer flower sites.
TEMPERATURE: Cannabis is a very hardy plant and can survive cold and heat well. Just like you or me though, it can get stressed and not function well in the extremes. Cannabis can freeze or boil to death. It can stop growing or go into stasis. It will go into survival mode if the temperatures are too high or too cold for too long. Twenty-seven degrees centigrade is the accepted ideal for vigorous cannabis growth. Indoors this is easy to achieve with fans, air conditioning units, heating and cooling mats. Lights will certainly generate heat that needs to be vented.
