A male plant is often long and thin and has fewer leaves. The moment the plant starts to flower, a male plant has seed male flowers or seed ‘balls’. A female plant will never have these but she has flowers and resin. A male plant can fertilise 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. We only sell female seeds.

No, we do not sell male seeds.

If you don’t intend to use your seeds immediately it’s important to store them properly. If you fail to do so, they may lose germinability and may become unusable. It is vital that you store seeds properly if you want to cultivate plants later. Store seeds in a cool, dark place, the refrigerator is perfect for that. Store it airtight at a temperature between 3 and 7 degrees Celsius. If you have stored your beloved seeds in an airtight, watertight manner in a dark place at the right temperature then they can be kept viable for up to 2 years.

If stored correctly, cannabis seeds have an excellent shelf life and could in theory be stored for at least 10 years. However, the success rate of the seeds germination does drop significantly after two years of storage. When you decide to germinate old seeds, make sure to take them out of the refrigerator at least 12 hours and then soak these older seeds for 12 hours in 22C° water with a couple of drops of hydrogen peroxide to soften the shell.This way the seeds can acclimate, which will increase the chance of germination.

Best results are reached by first germinating the seeds in a controlled environment. It increases the chance that the seeds germinate well. When you directly put seeds in the ground without germinating it first, it is probable that a part of the seeds will not come up.

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 95% of the seeds will germinate.

No, during germination there is no need for extra light. Providing extra light can even disturb the germination.

Common problems are: temperature too low environment (cottons) too wet used incorrect water.

Cannabis seedlings thrive in humid conditions with a gentle breeze in bright indirect sunlight with a temperature in the range from 21°C to 23°C. Preferably no drops of water on the leaves.

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.

May is the best month to start. It is still possible to cultivate 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.

Yes, if you use lamps you can grow cannabis indoors throughout the year, as you determine the climate in the cultivation room yourself. Light is the most important factor to successfully grow cannabis.

Strains that have proven to bring high yields are Amnesia Mac Ganja Haze and The Empire of the Sun. The yield is mostly determined by the conditions. So, do not just focus on the yields that seed producers mention. These large yields are often obtained under ideal circumstances; with a lot of light and with the right fertiliser. But you yourself are the most important factor for success. Love and attention result in the biggest harvests.
