Choosing a Strain
Because we offer the largest selection of strains in the world, this can sometimes get overwhelming when trying to decide which one to order. Choosing is not as difficult as you may think. There are really only three sides of the marijuana family we are talking about here. Indicas and Sativas and Ruderalis.

Indicas originally come from the hash producing countries of the world like Afghanistan, Morocco, and Tibet. They are short dense plants, with broad leaves and often grow a darker green. After flowering starts they will be mature in 6 to 8 weeks. The buds will be thick and dense, with flavors and aromas ranging from pungent skunk to sweet and fruity. The smoke from an Indica is generally a body type stone, relaxing and laid back.

Sativas are just about the opposite of indicas. They are tall, thin plants, with much narrower leaves and grow a lighter green in color. They grow very quickly and can reach heights of 20 feet in a single season. They originally come from Colombia, Mexico, Thailand and Southeast Asia. Once flowering has begun, they can take anywhere from 10 to 16 weeks to fully mature. Tastes range from earthy to sweet and fruity. The stone of a Sativa is cerebral, up and energetic.

Combining different indicas, different sativas or a combination thereof creates hybrids. The resulting hybrid strains will grow, mature and smoke in relationship to the indica/sativa percentages they end up containing.

All of the strains in the catalogue are divided into these categories:

SATIVA These strains are 100% sativa.
MOSTLY SATIVA Sativas crossed with about 40% indica.
INDICA/SATIVA These strains are roughly 50/50 indica/sativa.
MOSTLY INDICA Indicas crossed with about 40% sativa.
INDICA These strains are 100% indica.

The actual percentages of indica and sativa that all of the strains contain, is almost impossible to calculate exactly and not all breeders provide us with this information. When you look at the strains in each category, you will see that they are all very similar in respect to their growth, size, flowering time, yield and type of high. This is consistent through each category and is the most important aspect of choosing your strain.

Next thing to decide is if this will be grown indoor, outdoors or both. Whether or not a strain can be grown outdoors depends on the length of season you have. All outdoor and indoor/outdoor strains listed in the catalogue include an approximate finishing date outdoor. This is most important feature to consider and is completely influenced by the indica/sativa ratio. You want plants that will mature before the danger of frost or bad weather comes along. The more sativa that is in the mix, the longer it takes to finish. If you have a very long growing season, most strains in the catalogue can be grown outdoors. These finishing dates are approximate and will vary depending on conditions. From there you go back to what you like and the descriptions of the plants.

For indoor strains, don't choose strains that are listed as outdoors, they don't always transfer inside as well. It can always be accomplished but it may take a few crops to settle them in. Flowering times and yields listed are approximates and can vary depending on conditions.

The heights listed for each strain are for full sized plants. When growing indoor, we have complete control over how tall these plants get, just by how long we grow them before flowering is initiated. Artificial lights do not efficiently penetrate much more than 3 feet down into the garden, so it makes little sense to grow them much bigger than that.

After the light schedule is changed to 12 hours on and 12 hours off, flowering will begin in about 7 to 14 days. During this time the plants will continue to grow another 6 to 14 inches and then stop. How much they will grow depends on the indica/sativa ratio of the strain. Sativas will stretch the most. Depending on this ratio, flowering should be initiated at around 18 to 24 inches to achieve the end height of 36 inches. How long it will take to get this tall depends on the strain and the conditions in the garden.


You'll notice that some strains of the same name listed in the catalogue have enormously different prices. Here's how that all works; The expensive strains are coming to us from the major seed banks in Amsterdam. They have spent 30 years inventing and developing their strains, many of which have been multiple competition winners and are considered some of the best in the world and as a result command a higher price in the market place.

The lesser-priced strains of the same name come to us from local breeders who have taken those Dutch genetics, grown them themselves, have chosen the parents carefully and produced seeds. They have not invented the strain or done the same amount of work to command the same high prices. The quality is the same but the plants may be somewhat different from the originals, depending on the parents chosen. In all cases the result are a good representation of the strains.

My price range for 10 seeds is minimum to maximum:


All of the strains we carry are potent. The success of the eventual outcome will depend on your personal tastes and the conditions in which they are grown. Only dutch passion tests the THC percentages of there strains and we^^re not really sure what the numbers mean when they do. THC is found in the resin glands that form on the plant during the maturation process. These glands act as a shield to protect the seed from the searing heat of the sun. From our experience this is needed more in a hot, dry atmosphere, than a hot humid one. To maximize resin production drop the humidity in the room for the flowering stage, the lower the better. But no matter how much resin you induce on an indica it's still not going to give you the stone of a sativa, so it does have a lot to do with your personal tastes and expectations.


All of the yields listed for the strains are approximate and depends a lot on how they are grown and the quality of the environment. Indoor lights don't penetrate down very far so it is better to grow a larger number of smaller plants to achieve the highest yield of top quality bud. Maximum yields indoors are coming from indicas and mostly indica hybrids, while the more sativa in the mix, the lower the yields tend to be.

Our yield indoors is really limited only by the amount of light we have not the strain we choose. Given that it is a good growing environment, we would expect the yield to be about the same from any strain in relationship to its indica/sativa content. It is up to us as growers to maximize our plant's potential in our space. To do this we need to experiment to find out how each strain will respond best.


Flowering times listed in catalogue for each strain are an indication of how long it will take the plant to mature indoor after flowering has be induced by changing the lights to 12 hours of darkness. This will be affected by the environment to some degree, but is pretty much fixed in the plant. Indicas are faster flowering than sativas and hybrids are in relationship to the percentage of each they contain.

Equally important in the process is vegetation time, or how long you grow them before flowering is induced. Sativas grow very quickly and if we wait too long to flower them they will outgrow the limits of the space and will not fill out. On the other hand, if an indica is not grown for long enough, the yield can be greatly reduced. In the scheduling of the process they can often both end up taking about the same amount of time to grow and mature. 2007 Seeds
