What is the difference between male and female marijuana seeds?
The marijuana plant or cannabis plant is an hermaphroditic plant. This means that there are male and female plants. The female plant has flowers and resin and is used for the cultivation of marijuana. The male plant only produces pollen, which has no further application.

A male plant can fertilize a female plant so a female plant will produce seeds. The result of the production of seeds by the female plant is that energy is lost and this results in a smaller harvest. For this reason male plants are not used and removed. Therefore we only sell female seeds.

How do you recognize the difference between a male plant and a female plant?
A male plant is often long and thin and has therefore fewer leaves. The moment the plant starts to flower, a male plant has seed male flowers or seed 'balls', a female will never have these. We have a complete article on our website about recognizing a male or female plant: Male or female cannabis plant

Can I grow a male myself?

Yes, you can grow a male marijuana plant yourself if you start with regular seed. Regular seed are seeds that are not feminized.

Do you also sell male or regular seeds?
Because there is very little demand for regular or male marijuana seeds, we do not sell male seeds anymore. We only sell feminized seeds that develop into female marijuana plants.

Why do you first need to germinate your seeds?
The best result is reached by first germinating the seeds. This is better because when you let the seeds start in a controlled environment, it increases the chance that the seeds germinate well. When you directly put the seeds in the ground without germinating them first, there is a high chance a part of the seeds will not come up.

How do I best germinate my seeds?
Germination goes best between humid cottons in a controlled environment. If you germinate in a petri dish with cottons, water and the right temperature, up to 90% of the seeds will germinate. A germination kit is also included with our Private Label seeds! If you prefer to grow another brand of seeds, this handy germination kit can also be purchased separately.

Is it possible to cultivate without lamps?  
Yes, that is possible if you grow outside. Start in May with germination and from mid-May you can put the plants outside. The more sun for the plants, the better. Cultivating indoors without lamps is not possible. Cultivating without light in a greenhouse is possible though.

Where and how do I need to preserve my seeds?
You best store seeds in a dark and cool place. You can store seeds airtight and put them in the fridge, for example. Ensure that the seeds are packed airtight, so they won't get humid and start the germinate without you wanting to. 

What is the best time to cultivate outdoors?
May is the best month to start. It is still possible with cultivating in June. If you want to start in July or August, it is better if you choose an autoflower because these start to flower faster. So, you can still obtain results in time.
