Citral had been added in 1993 as a clone and as seed to the library of the Positronics Sinsemilla Fanclub. This happened with the original variety and can not be compared with the citral that appeared later on the market.
At first the plant was very popular for indoor uses, until it was discovered that the plant was also very useable for outdoor growing. An early-flowering Dr. Weed man was crossbreeded with a Citral female plant, which had been selected from seeds.
The resulting seeds were breeded with original Citral mother-clones, until a new species was breeded that was stable and fungi-resistant.
Double fun gives a strong psychoactive product that shall also always work with daily uses and that shall never bore you!

Mutation of the regular Double Fun.
The seed from this plant originates from two pure Double Funs which finished two weeks before the regular Double Fun. A bonus plant so to speak.

No Mercy Seeds Regular Santa Maria F8 (10seeds)


About eight and nine weeks of flowering.
Few leaves, which makes trimming and cleaning easy.
Effect is high and releases much energy, taste is full of flowers and fruits, while the high seems to last forever.

The yield, which is extremely high made this a very popular plant for over ten years.
Santa Maria, a variety of marijuana stemming from the Brazilian Amazon where it has been used in a spiritual context, is now available in the Netherlands

While Santa Maria is not being used for spiritual purposes in the Netherlands, out of respect for the plant it's name has been changed to Planck…
The distribution in Holland of the real Santa Maria clones was done by the former Highlife-magazine chief editor, Bernt Gundersen, because he was bringing his new "found" clones of a strain that is worldwide known by now... to No Mercy Supply... to Cees.
And you better be sure.... he took care of free distribution (50% of the Coffeeshops in Holland have the name Santa Maria on their price-list).
No strain in the world so famous... Santa Maria. Strange effect... no seeds available, this plant was cloned for at least 15 years, and nobody knows the genetic background.
Because this is originally an outdoor plant, Planck should be cut vertically. If you don't do that, the plant continues to grow and eventually perishes under the weight of it's own buds, which cannot be supported by the skinny stalk. By cutting vertically they grow rather widespread; therefore put only nine plants on a square meter and twelve on a square meter of rockwool. Planck doesn't need a prolonged growing phase; on rockwool no more than three days, on soil five at most.

Flowering time is between eight and nine weeks, which is modest for a plant that is 2/3 Sativa and 1/3 Indica. The plant has few leaves which makes trimming and cleaning easy. It's potency resembles that of a Shiva, while the white layer on the leaves might be expected with an Indica. On the other hand, the effect is so high and releases so much energy, that actually it could not be compared to any of those. The taste is full of flowers and fruits, while the high seems to last forever.

Something about the yield. Being a topplant, quality is the main issue here. On the other hand, the yield, which should be somewhere between that of a White Widow and a Special, remains highly surprising.

Genetics: mostly sativa
Flowering time: 8 weeks
Potency: Extremely high
Yield: 1 gram to a watt

No Mercy Seeds Regular Lucky Queen(10seeds)

A fast, strong and very “white” plant for both indoor and outdoor. This plant produces a lot of weight and will disappoint nobody. Lucky Queen is the result of an inbred Silver Pearl # Santa Maria which was crossed with a Santa Maria F3, which makes it an F1 hybrid. This F1 does not need to be inbred any further because in its present form delivers a superior product.

No Mercy Seeds Regular No Mercy Special (10seeds)


THIS IS IT!!! Many years of experiments and selections lead to the resulting best genetics we've ever experienced! This plant has the REAL NO MERCY SPIRIT !!!

Our figurehead!
Santa Maria # Mexican Haze crossed with a Victorie.
It took many years of testing to bring out this amazing plant.
Even though she requires 70 days to mature, she’s absolutely worth it.
The No Mercy Special contains top genetics and has surprised several well known growers. 

No Mercy Seeds Regular Desert Queen(10seeds)

Desert Queen is a strongly inbred F1 hybrid and one of our most underestimated varieties. Desert Queen is basically an indoor plant, though it will produce spectacularly outdoor in warmer and dryer climates. This is one of those rare varieties that combine true sativa traits with a remarkably short flowering time of only 9 weeks. Due to it's strong sativa parentage on average it grows 30 cm taller than our other varieties, but not as uncontrollably as many other sativa's. Flowers are thick and form huge cola's on the main stalk, while lateral growth is limited, making this Queen a dream plant for those who dread the chore of manicuring. A perfect choice for growing in a sea of green system, we recommend to use 30 plants on a square meter for optimum results.
As you can expect with her name, Desert Queen is very drought resistant. We recommend to adjust the pH of the medium a little higher than usual; 6.0 would be ideal for this lady.
The abundance of top genetics in Desert Queen created a fast and strong plant, that's a big yielder and produces an excellent smoke. The high is profound, the taste sweet and spicy.

Genetics: 95% sativa / 5% indica
Flowering time: Indoor: 9 weeks
Potency: very high
Yield: Indoor: 1 gram to a watt

No Mercy Ice Queen

 The growing demand, from all over the world, for seeds has stimulated us to let you enjoy the results of generations of development, besides our female seed-strains...
No Mercy proudly presents a crossing between a Master Ice and a Valley Queen, we call her :
Ice Queen

The Valley Queen is by far the strongest plant we encountered in years! It's an Everest Queen which we crossed with a Silver Pearl ...

The Master Ice has become a famous one. It's an extremely fast-growing plant, that is not sensitive to moulds and does produce very, very much resin...
(For the insiders: Mind Bender x Northern Light Xtra.)

Absolutely a top-quality weed ... No paranoia, no stress ... Just an honest high.

About 8 weeks of flowering... and you're done!

A little bit more fertilizing in respect to the common species is necessary!

How to germinate seeds No Mercy Style


This information was produced when we realised many growers in the Netherlands are quite advanced when it comes to growing, but have no idea how to germinate and cultivate a seedling successfully. That's inevitable in a 'clone culture' such as ours. However, the arrival of feminine seeds urges the availability of more information on this subject. Experience is more useful than anything in this matter. Here you'll find some advice and possibilities to allow your seedlings to become robust and healthy growing/flowering plants.

Growing Media: Rockwool plugs, Rockwool blocks, Pots with soil, Jiffy Pots, Outdoor


Rockwool plugs
A fine medium for germinating. The biggest problem is that you'll have to move the plug to a block or soil in a matter of two to three days. After all, you'd like to give the penroot an optimum chance of developing fully. In other words: it's preferable to directly sow into the bloc to prevent unnecessary work.

Rockwool blocks
Especially a fine medium for large-scale growers. Flush your blocks very well (with pH 5.3) to lower the pH value of the medium and put the blocks on top of each other; rockwool on rockwool. You'll notice the water is drawn away from the top-blocks, so you don't have to deal with a saturated block for at least a week. Regulating humidity is crucial. Now put 110 blocks (of 7.5 by 7.5 cm) in a so called Duma tray, or 220 on a 'Danish tray', and fill the holes in the blocks with sowing/germinating soil (read General Notes). After sowing, about 0.5 to 1 cm deep, cover everything for about two days with plastic to prevent from drying and keep the tray in a warm space. Make sure the tray gets lit after those two days, for at a temperature of 23°C the seeds will germinate within two days. Experience has shown that by doing so the plants don't lose a minute of their growing potential when you put the blocks on the slabs after 12-14 days.

Pots with soil
The most beautiful, the best, the most natural and easiest medium. Use well pre-fertilized potting soil, fill the pots to about three quarters of their volume with this soil, fill up the remaining quarter with sowing/germinating soil. Press the combined content of the pot to an even surface to prevent the water from flushing away the seeds while watering (use a small watering-can or sprayer). Plant the seeds 0.5 to 1 cm deep. Preferably use disposable plastic pots, from which you cut out the bottom later on to allow for a smooth transient to the slab or bigger pot later on. These pots can be placed directly on top of the slab. Make sure you fix the drippers at the back of the slab and not in the pot. The reason for this is that the plant releases it's waste (salts and minerals) in the top layer of the medium, and it's not a good idea to flush this waste to the drinking roots every time you water. Another benefit is that you can place considerably more (female) seedlings on a square meter than you could with clones.

Jiffy pots
A more expensive method which has both advantages and disadvantages; the pots dry out very rapidly, and are only suitable for soil cultivation. When they get too humid, molds develop quickly. A fine medium, but you have to observe them carefully and move the seedlings to their real medium as soon as possible. The biological approach will appeal to many, but on a larger scale you'll most likely encounter difficulties.

The most natural way, but very much depending on the wheather. Especially in countries with a sea climate, such as
Holland or England, plants come through their vegetative stage pretty nicely, but get lost because of too much humidity in autumn. Don't take any risk with sowing, and sow only when you can be sure there will be no more frost. Only when temperatures increase, the plants will develop real growing speed. Don't sow any deeper than 1 cm on a soil that is as 'airy' as possible. When it doesn't rain make sure the soil keeps somewhat humid in the following days. Note that the seeds don't like to swim! Extra nutrition should not be necessary during the cycle, but if you don't use fertilized soil give the plants some water to which you have added some fertilizer every two weeks. Make sure you don't water directly along the stem to prevent unnecessary salts and minerals to reach the drinking roots. Growing indoors at first is an option, and gives you the opportunity to control the number of light-hours. If you keep the plants under 20 hours for a long time, and putting them outside when the daylight is already decreasing, you gain time and your plants will reach the flowering stage sooner. Make sure the plants don't stagnate and keep going, for that of course is essential in this case.



General Notes
Make sure you choose a sowing/germinating soil which contains a lot of fine sand. Masonry sand or sand for playgrounds as an addition is just fine. Too many fibres cause problems with germinating. If you want to be absolutely sure and create an optimum chance for each seed, sieve the soil mixture before use! The helmet (seed cover) and the film which envelopes the seed should remain in the medium when the seeds germinates. Too light a soil will hamper this process. Keep your water to pH 6.3, and keep the seedlings humid, but not TOO wet. A fine water sprayer works miracles here. Make sure the seedlings receive FULL light when they germinate and leave it like that for at least 20 hours the first couple of days. Make sure your tube lights hang as close to the seedlings as possible (a couple of centimeters)! A 400 watt lamp can be hung as low as 45 cm and a 600 watt lamp as low as 55 cm.

Don't be afraid, the seedlings can very well handle this, even though a good movement of air underneath the lamp is very important (ventilator!).

Make sure you spray in time, until the hull, that may come up when the seed germinates, has dropped off, as well as the protective film which envelopes the seed. This is necessary to prevent the hull and protective film to dry out, which sometimes result in sticking to the germinating seedling, which as a consequence, is hampered in it's development. Stop spraying water when all seedlings are overground, too allow for your seedlings to work at maximum efficiency underground. Offering too much humidity to the leaf often results in a less developed rootsystem. Contrary to clones, seedlings have a reasonable resistance to dry air. When using germinating trays, things often go wrong because of excessive heat and humidity.

Because we germinate and grow our seeds indoors on a warm medium, the plants tend to shoot up rather thinly, which causes weak and excessively high plants. This can only be prevented by hanging the lights as low as possible.

Lowering soil temperature could be an option, if it weren't for the growing speed we don't want to lose.

The biggest mistake being made is: not bringing the light close enough to the developing seedling!

Remember that the first two to three hours partly determine the rest of the plant's life!

Start giving some nutrition only after the plants have been in the light for two days. Start with a very light nutrition and keep the water to pH 6.3. Note: the ballast caused by a measurable EC in your tapwater can NOT be seen as nutrition. If you don't have a pH measuring device at hand, try to work with rainwater or add a drop of natural vinegar to the water - and be aware that your first purchase 'should' be a pH meter. Preferably use 'pure' nutrition that could also be used as leaf-nutrition. Doing so minimizes your chances of failure.
