What is the difference between ACE Seeds and other seed banks ?

ACE Seeds develops a sophisticated preservation work and studies the pure varieties of psychoactive cannabis proceeding from all over the globe. Initially, the native varieties are reproduced in pure form for their future preservation. After analyzing and preserving them, hybridization projects are developed mixing several pure varieties in order to combine the best characteristics of each one.

In that way, we offer new and different hybrids that accomplish the current breeding standards: with high adaptability to different growing types (indoors and outdoor growing), with fast maturation, high potentiality, high production of flowers and resins, refined terpene profiles, ornamental qualities, etc...

By offering ACE Seeds pure varieties and new stabilized types and by developing hybrids with new genetics, we contribute towards the improvement of the lack of genetic diversity suffered by the commercial psychoactive cannabis varieties nowadays.

What is the difference between regular seeds and feminized seeds ?

Regular seeds can produce feminine plants as well as male plants. They are most indicated if you are interested in using male plants to produce seeds in your own breeding projects. If the growing conditions are adequate, the percentage of feminine plants is normally superior to the one of male plants. This is especially true for the most tropical sativa varieties, where the percentages of feminine plants usually go beyond 70-80%.

On the other hand, feminized seeds produce only feminine plants (the percentage being over 95-98%). They are most indicated for growing without seeds where the priority is to maximize the number of feminine plants since the very beginning, or to avoid any problem of undesired pollination from male plants.

What is a pure strain ?

A pure strain is a native variety coming from a very concrete geographical area. Thus, they show some of their own typical and stable characteristics after many generations of being adapted into these concrete climate conditions. This makes the pure variety to be unique and distinguishable from the rest of the varieties.

Pure strains can be wild-grown or they can be the fruit of centenary domestication relationships with the human being. In any case, these pure varieties have an incalculable genetic value for their preservation. In fact, they are unfortunately rapidly disappearing but they are the basis for the development of all commercial existing varieties.

They are mostly indicated to hybridize because the features of the pure varieties are more homozygotic and stable, so that the hybrids produced have a more predictable behavior.

What is a hybrid ?

A hybrid is a crossing of two or more pure varieties, whether stabilized or not.

Several varieties are crossed in order to obtain a more vigorous hybrid than the original genetics, trying to combine the best characteristics of each pure variety and reducing to a minimum the negative characteristics of each one.

This is the reason why the hybrids are more productive, powerful, adaptable and easy to grow than the pure varieties from which they are developed. However, their genotype is more unstable when crossing seeds in breeding projects.

What is a semi-stabilized hybrid ?

It is a hybrid where the stabilization breeding is still in a development stage. Therefore, some variability could still be found regarding the typical characteristics of the strain.

What is a stabilized hybrid ?

This hybrid is the result of crossing other pure varieties or stabilized varieties. It offers whole stable and recognizable characteristics that, generation by generation, make it almost behave as a pure native variety.

What is a limited edition ?

Limited editions are exclusive varieties that are offered for a limited period of time and normally they are sold in reduced stock. If you are really interested in any limited edition, we recommend you to buy it as soon as possible because we cannot guarantee these varieties will be available in the future.

What are the conditions of conservation and packing of the seeds ?

In order to guarantee the correct conservation of the seeds and maximize the viability of germination, the seeds are preserved in hygienic conditions at a constant temperature of 4ºC. The levels of humidity are low and constant too.

The seeds are selected by hand, one by one, in hygienic and clean conditions. They are selected after proving their color and size. Each one is pressed in order to make sure that the embryo of the seed is already mature. Afterwards, the seeds are introduced in a transparent tube of rigid plastic together with granules of silica gel that guarantee the low humidity (necessary for the conservation of the seeds) and to avoid the seeds are crushed during the delivery process. Finally, the tube is covered in a plastic, in order to avoid any potential manipulation until the customer opens his/her package.

Standard mail is usually more discreet, but we are unable to provide a tracking number of the shipping. No signature is required on arrival.

ACE Seeds will not be responsible if the registered mail is confiscated by customs officer or if the standard mail shipping is lost during the delivery process.

Can I choose to receive the seeds without the original packaging ?

In order to make the shipping more discreet, the customer can choose to receive the seeds without the original packaging. If that's the case, ACE Seeds will not be responsible if the seeds are crushed during the delivery process. Our original packaging has been designed to protect the seeds.

How should I do to germinate my ACE Seeds ?

1. Wash your hands. Put your seeds in a clean glass of distilled water with pH 7 and very low levels of EC for 12 hours.

2. Prepare a clean Tupperware (or a plate) and clean kitchen paper. Cover the Tupperware with two layers of kitchen paper. Put the seeds on them, and cover the seeds with one layer of kitchen paper. Now humidify the middle part again with distilled water (or mineral quality water). Please make sure that no water is stagnant, but only the kitchen paper is homogeneously humid. Close the Tupperware.

3. Put the Tupperware in a dark place with a stable temperature around 25ºC. For the tropical sativa varieties, we recommend higher temperatures of around 28ºC. In order to maintain the temperature warm and stable even in the coldest months of the year, it is recommended to put a thermic mat under the germination Tupperware or plate. Keep controlling that the temperature does not increase.

4. Open the Tupperware at least twice a day in order to regenerate the oxygen of the germination and to control the state of the seeds.

5. When the seeds start opening (usually 24-48 hours after the germination) and they have a white and healthy root of approximately 1 cm, they must be very carefully introduced in the selected pot. The depth to which they must be introduced is approximately 1 cm. Please make sure that this white root looks downwards. Now humidify the place with abundant distilled water or mineral quality water.

6. The plant pot must be put in a sunny place or under the breeding light with a growing photoperiod. The temperature must be kept stable at 25ºC and not less than 20 º C in any case.

7. Wait until the plants are born and enjoy your growing!

How can I reclaim if my ACE Seeds do not germinate ?

ACE Seeds makes germination tests to all the batches that are put on sale. Nevertheless, it might happen that a customer has bought an old or defective batch due to improper conservation or transport. This is why we ask you to keep the original package until the seeds have correctly germinated.

However, if you have any problem with the germination, please let us know the number of your order (or send us a copy of the invoice of the purchase in case you bought it from a retailer), send us the photo of the original package with the packing date, and a photo/s of the germination process to: info@aceseeds.org.
