Super Silver Haze (Amsterdam Genetics)

Cannabis seeds can only be ordered by collectors. This is because of compliance with the Grow Shop Act. Therefore, we are obliged to deny certain purchases.

Growshop Act

If we notice that certain products are used for illegal use, the purchase is directly canceled. Purchases for large-scale or professional cultivation are strictly prohibited. We only sell for personal use. Each customer can order up to 25 seeds.

Cannabis Seeds are Natural Products

Sometimes we take things completely at face value. Cannabis seeds are natural products. This means that the values which we specify are average values. We try to specify the following values for each seed. They are values given by the producer, values requested from known authorities, or average values which growers themselves have specified.

• The length of the flowering period
• The final height of the plant
• The month in which you harvest
• How long the plant needs from seedling to harvest (for autoflowers)
• The yield
• The percentage of THC and CBD and the ratio to each other

These figures are useful for comparing weed seeds. Because the final plant and your yield are strongly dependent on all kinds of factors, such as feeding, the weather, watering and the growing medium, no rights can be derived from these values.

This is how you germinate cannabis seeds with success

Let's start with what you should not do: Never put your cannabis seeds in a glass of water for more than 6 hours and do not place seeds in light - certainly not in direct sunlight. Also, do not put your seeds directly in the ground. Although this is natural, you have to realize that we as a grower can germinate much better than nature. A cannabis plant produces hundreds of seeds in nature because things go wrong so often.

Germinate your seeds with the proven coffee filter method or use our germination kit with included instructions. No Dutch-Headshop germination kit? Lay a coffee filter horizontally and spread your seeds in it. Moisten the coffee filter with lukewarm spring water and hang it on the inside of your kitchen cupboard, for example. Every day, preferably in the morning and in the evening, moisten the coffee filter again, so that your seeds never become bone dry. After about 5 days, but certainly within a week, the seeds will be ready to plant (root down).

Phenotype and Feminised

If we state that a weed seed is pure Indica, we mean that the genetics of the seed contain only Indica. Although it is unlikely that the plant will then grow like a Sativa, it is still possible that the plant will have longer and narrower leaves than we specify. We call what the plant looks like, the phenotype of a plant.

Feminised does not mean the same as feminine. Feminisation is a complex process whereby both we and other seed producers ensure that you are supplied with a feminine weed seed. But because the gender of a weed seed cannot be influenced 100%, it can happen that a male or hermaphrodite (bisexual) gets in with the seeds. Nevertheless, the chance of this happening is negligibly small. 

What if you see a hermaphrodite or male plant amongst your plants? In that case, remove it as quickly as possible. It can spoil your harvest. No idea how to recognise a male or female plant? Then get hold of our blog and look for ‘male’.
