I soak for 24 hours, if the seed falls to the bottom with a tap it's good, and saturate the soil while I soak the seed. Hollow out a little depression, plop it in (tweezers help,) lightly cover. Just spritz the top once or twice a day to keep it from getting too dry. Don't need to water otherwise for over a week after day 1 (in 5G fabric pots,) start with .5L and go up from there. Works well for me

This is a myth, if the seed still floats, throw it in a wet paper towel in a baggie on the wifi it'll pop

Satisfy your EC deficiency
So with this test, 3 seeds soaked in water until they split and then planted in soil took 5, 6, and 8 days to pop up. The 3 planted directly took 4 and 5 days to rise above the soil. Now what am I going to do with 6 plants in a 12x14 footprint??
With Autos its a general rule to just pop the seed into it's final pot do not transplant as they're fragile. I have had 100% success rate this way with Autos, make sure you soak the soil through and wait to heat up a bit. Then make a hole with a screw driver no more than 1cm drop it in and cover. Keep humidity up around 70% and hey presto [emoji6] usually takes 3-4 days at most sometimes longer. Remember each seed is different.

I have a tub with a lid I line with tissue, fully soak the paper and pour off the excess then pop the seeds in and leave them in a dark place. While they germinate I soak the soil thoroughly then once there's a taproot out of the seeds, I take a biro, poke a hole in the soil, pop the seed in gently, root side down and cover with a sprinkle of soil.
After reading this thread, I'm gonna get leaving my tub on top of my WiFi next time. Warmth and moisture is all you need to germinate them [emoji16]

I soak mine over night for about 8 hours. I tap them to see if they sink. I use to think if they did not that they were not going to sprout but years ago found out that is not true. I have had seeds sprout that did not sink. I also think a lot of new growers don't understand that you can also drown a seed even in paper towels.
This is what works for me..
I drop the beans in distilled water for 24hrs. I drop them in soaked jiffy pots 1/4" down then cover them up. This has worked everytime I have tried it. I just took this tonight, my new batch ready to go.

Just as an update I tried everything suggested for my seeds but failed to sprout either. I feel like a loser 
what a way to start. Did the soak then damp paper towel method. Then tried soil for a few days. Emailed Herbies to get more and chucked in the trash. I will try again. I have some from gorilla trapped in the limbo that is Chicago customs.

Here is some info from one of the seed suppliers and their view on germination:
Understanding Risks of Pre-Germination
For an optimal germination result the seeds should be planted DIRECTLY into the substrate. We clearly advise against using pre-germination methods or soaking. Please do not place the seeds into a glass of water or in moist paper tissues.
This does not mean that pre-soaking should never be used with seeds from other sources, or that we criticize growers who prefer this method. We are aware that some breeders recommend it for their products. But to prevent complications and achieve the consistent level of high germination rates that you should be getting from our seeds please trust our advice and follow our guidelines.
Please take note that customers who soak their seeds in water or wet paper tissue do so at their own risk. We are not accountable for any failure in germination or complications caused by this method.
Fresh and healthy seeds prefer a nurturing and airy substrate to germinate in – just as mother nature has meant it to be. Cannabis is a plant species originating from semi-arid and temperate biotopes and the vast majority of modern cannabis hybrids contain a substantial percentage of these genetics. Cannabis seeds are not adapted to swampy wetlands, but they are suited for germinating in well drained soil/substrate. In nature they rot if they fall into a puddle of water...and there are no paper tissues lying around either. Taking into account these botanical facts, it is quite logical that by creating germination conditions that are similar to those of the natural habitat you can expect the best results.
What happens if one uses pre-germination methods?
Soaking seeds in water/wet paper towels is a method which can be used for old seeds (3+ years) that are drying up and losing germination power; and for pure land race equatorial strains such as from Africa. Both factors do not apply to our seeds. Fresh seeds have a healthy embryo whose cells are filled with water. But excess water causes the cells to bloat, depletes oxygen and leads to the tissue rotting away before the seed embryo can germinate. Old seeds have lost water in the cell tissue, the embryo starts to shrivel, which is why germination rates drop the older the seeds are. Therefore, old seeds (ie. 3+ years) can soak up more water before adverse conditions cause them to rot. This is one of the main reasons why various seed stock reacts differently to pre-germination methods. Some growers make the mistake of soaking our seeds in water for up to 1-2 days because it may have worked in the past with other seeds. This does not mean, however, that this method can be used for all seeds. In fact, old stock or equatorial cannabis seeds should only be soaked in water for a few hours at the most. Always consult the web site of a seed bank for specific advice and instructions on how to germinate their seeds.
It is in a growers best interest to choose a germination method with the lowest risk of complications. Because we want customers to have the highest success rate possible we recommend the most convenient and safest method. This does not mean it is the only option. We simply believe it carries the lowest risk for germinating fresh seeds. Planting seeds directly in the substrate is also the most plant friendly method for any type of seed stock. The reasons are explained below in paragraph 2 & 3.
Placing healthy & fresh seeds in water/wet tissue can lead to the development of fungi or bacteria on the seed hull. Lack of oxygen and contaminating substances in the water/wet tissue promote fungal growth which can be transported to the substrate later on. Often the seed simply rots away if left for too long in a glass of water, or wrapped up in wet tissue.
Once the seed sprouts in a glass of water or paper tissue it already has the taproot growing out of the cracked seed hull. While transplanting the germinated seed it is very difficult, indeed impossible, to prevent damage to the delicate taproot. Many sprouted seedlings handled in this way show retarded development, or even simply fail to appear out of the substrate after transplantation. Handling seedlings this way can impair the health & vigour of the plant for the duration of it’s life cycle - especially if other disturbing factors occur during the early stages of growth.
Professional horticulturists rarely use pre-germination methods to actually grow out the seedlings because of the shock suffered from transplanting them. For example, we use the paper tissue method only as a quick test for germination rates of aged seed stock from our genetic repository. This allows us to see beforehand how many seeds we have to put in soil to get the amount of plants we require for breeding projects.
How to Germinate our seeds
Please use high quality soil that is suitable for seedlings, or use rockwool starter cubes for germinating seeds.
Do not use jiffy’s/peat pellets: the acidic pH of pure peat can inhibit germination of cannabis seeds. Results are unreliable and depend on manufacturers, some add limestone to raise pH, some do not. Growers have also experienced problems using rapid rooter plugs (with various types of cannabis seeds). Any growing medium used for germination must also have the correct pH for cannabis seeds.
For optimal results we advise against the use of jiffy's, peat pellets, and rooter plugs. If you are absolutely keen on using such products you should at least test the product first with a few expendable cannabis seeds before sowing your valuable seed collection.
SOIL
Take 8-10 cm/3-4” (diameter) pots or a seedling tray and fill with quality potting soil. Press the soil slightly down and make a 1,5 cm/0,6” deep hole with a pencil or finger. Place the seed in a horizontal position in the hole (this is the easiest method). Fill the hole and gently tap down the soil. Use chlorine free water (preferably good mineral water without gas) with a pH of 6-6.5 to water the pots. The soil should be uniformly moist and properly watered, but not soggy or waterlogged. The pots or tray should also not stand in a tray filled with water. Use a spoon or small beaker to dosage properly if you are unsure and want to avoid accidentally overwatering the soil. Put the pots or tray at a warm location and ideally under lighting. Temperatures at 25°C/75°F or higher accelerate germination. Take care that the soil does not dry out and that the pots don’t stand in the cold (ie. at or under 21°C/70°F). Misting the soil surface with water spray is not effective. You should water the pots properly if the soil surface dries up. Within 3-7 days the seedlings should appear out of the soil. You can switch on your lamps during germination to provide warmth or when the first seedlings appear. Since they might also grow out of the soil during the night it's best to have lighting switched on 24 hrs.
ROCKWOOL
Immerse the rockwool cubes in lukewarm water with a pH of 5.6-5.8 until the rockwool is evenly wet. Overnight soaking is not required for starter cubes. Let the water drip off...squeeze lightly to assist. Place the seed in a horizontal position into the hole (this is the easiest method). The taproot can grow downwards assisted by gravity. Alternatively, you can also place the seed into the hole vertically with the rounded end facing up (cannabis seeds sprout by opening the shell at the pointy end where the taproot grows out). Cover the hole with a small piece of rockwool. Choose a fluffy piece of rockwool...you don't want to tightly plug the hole because the seedling has to grow out with ease. Water the rockwool cubes with a weak nutrient solution of 10-15% of the recommended dosage (or EC 0,6) and pH 5.6-5.8. You can also germinate using pure water. Put the rockwool cubes at a warm location. Temperatures at 25°C/75°F or higher accelerate germination. Take care that the rockwool cubes do not dry out or stand in the cold (i.e. at or under 21°C/70°F). They should also not sit in water. Usually the cubes require to be moistened with pH adjusted water every 1-2 days. Use chlorine free water such as mineral water. Within 3-5 days the seedlings should appear out of the cubes.
Hot tip: to prevent the cubes from sitting in water put some perlite at the bottom of the tray for drainage.
You can switch on your lamps during germination to provide warmth or when the first seedlings appear. Since they might also grow out of the cubes during the night it's best to have lighting switched on 24 hrs.
IMPORTANT: Don’t cover pots with plastic wrap, don’t use a humidity dome to seal off the pots, or place pots/rockwool cubes in a propagator that’s completely covered! This prevents fresh air exchange, raises humidity to excess levels, and easily facilitates the spread of fungus. The seeds will rot before they can germinate. Excess humidity combines with lack of oxygen is the [HASHTAG]#1[/HASHTAG] cause for poor germination results!
If you germinate your seeds at room temperature, and have properly watered the substrate, there is no need to be concerned that it will dry out overnight. Only the substrate requires sufficient water for the seeds to germinate - the outside humidity can and should be be low to moderate (i.e. max. 55%). Low humidity in the room does not interfere with germination or healthy seedling growth.
Remember: cannabis is not an orchid! Fungal spores are everywhere: in the air, in substrates, ... and they await the conditions to spread and attack organic substances such as seeds or the roots. Common fungal infections are pythium and fusarium. Young seedlings are also prone to such infections because their cell tissue is very soft. Over-watering and/or high humidity trigger such diseases like “damping off” which quickly kills seedlings.
Heating mats should be avoided unless you need it in the wintertime. A dysfunctional heating mat, or a mistake in the temperature control, can easily boil the seeds or dry up the substrate and shrivel the freshly emerging seedling. Your pots/rockwool cubes should be placed in a space with ambient room temperature (ie. 24-26°C/75-78°F). In the winter use a small electric or gas heater to warm up your grow space. You can also switch on the HPS lamp and put the pots at a close distance underneath.
A [HASHTAG]#1[/HASHTAG] seed killer is a closed humidity dome/mini-greenhouse.
Humidity domes are only required for rooting cuttings.
Many growers make the mistake of thinking that they need a high ambient humidity for germination or seedlings. This is an unfortunate myth of cannabis cultivation. The high humidity and lack of fresh ventilation quickly causes fungus in the soil or growing medium and the seeds can rot!
Cannabis is not an orchid or swamp plant! The seeds need a well aerated growing medium to germinate well. Seedlings also cannot tolerate high humidity and can easily be attacked by fungus such as fusarium and pythium. Only the soil or growing medium should be moist for optimal germination and seedling growth. Ambient humidity is best at or below 50%.
You can use a humidity dome/mini-greenhouse as a tray for germination but you must keep the lid half-way open or completely seperate to ensure fresh air exchange and humidity levels at or below 50%.
This Indoor Grow Garden includes reusable trays that can grow the plants for a week until transplanting into a bigger pot. The trays sit beneath 2x2ft 24W fluorescent bulbs for healthy growth. This setup provides light & warmth, it also ensures that fresh air & average humidity levels prevent negative factors from disturbing germination. The lights are housed in the canopy of a sturdy aluminium stand that has an adjustable height (up to 38cm H from base) and a reflective hood to maximize usable light. There are many different models of fluorescent or CFL fixtures on the market to suit every taste and budget. Give seedlings maximum light to prevent stretching and support fast development. Use additional light from a window if available. For best results we recommend HPS lamps from the start. A 70-150W HPS lamp does not use more electricity than standard CFL lamps but provides much more lumens (light intensity). If you are growing with 250-600W HPS then you should germinate or put your seedlings under the lamp as soon as possible to ensure quick and vigorous growth.
Things to avoid
soaking seeds in water/wet paper tissue
humidity dome/mini-greenhouse fully covered
heating mat too hot
covering pots with plastic
germinating in jiffy's and peat pellets
wrong soil for germination
fertilizing seedlings
too much/too little water
cold and dark germination room
cold outdoor temperatures; frost
wrong pH of water
bad water quality
high EC of nutrient solution in hydroponics
spraying seedlings with water/organic teas/pesticides
Seedling care
Within 3-7 days the seedlings should appear out of the soil/rockwool cubes.
Step 1
Provide sufficient light. Seedlings require sufficient light (this applies to the strength and length of daylight or artificial light) and fresh air to grow. Switch on your lamp(s) as soon as the first seedlings appear at the latest. Seedlings should be moved directly under a HPS lamp if you have one. The more light your provide the better your plants can grow. Not all strains are suited for low light such as CFL lamps and fluorescents. Make sure you choose the right strain for your lights.
Step 2
SOIL
As soon as the first pair of leaves grow on the seedlings transplant them into 14-16 cm/5,5-6,5” pots, so that they have sufficient space for their root development and nutrients. You can also choose larger containers if you are confident that you will not over-water. We recommend a 4-5L/1 gallon container for the first 4 weeks of growth and subsequent period of sexing under 12/12. Repot females into larger containers after sexing.
HYDROPONICS
Start with a mild EC such 0.7-0.8 and slowly increase the EC of your nutrient solution after one week of growth. The best EC depends on the quality of your water and it's basic EC level. If the water has a high EC then you should filter it with a household reverse-osmosis filter and mix this 50-50 with tap water.
Step 3
Do not fertilize in the first weeks of growth on soil! This is the [HASHTAG]#1[/HASHTAG] cause for sick plants. Transplant into quality horticultural grade potting soil and bigger containers as the plants grow larger. Rootbound and sick plants should be avoided. Our plants grow quicker and more vigorously than most other strains. Do not let your good plants vegetate in tiny cups and cramped pots. You can get a high % of males or male flowers on your females if you do not care for your plants properly.
Recommendations
Take advantage of our low prices and plant an extra 1-2 seeds if you don't use the whole pack of 10 seeds. Although we, and the plants, do everything in our power to produce 100% viable seeds please remember this is a biological product. Therefore, even if a seed looks perfect from the outside, it can't be prevented that a minor % of seeds does not germinate, or that the seedling is not completely healthy. That's why it's a good idea to have an extra seed sprouting as a back-up and then you can always select the best seedlings for your grow.
Keep your fingers from those fertilizers and potions. Yes, it happens again and again: growers feeding their seedlings on soil with mineral or biological fertilizers & rooting products, spraying them with homemade teas, or killing them not so softly with harsh biological pesticides. Seedlings are baby plants with delicate young leaves and roots. Let's put it this way: you don't feed a T-bone steak to a baby. Seedlings require 3 weeks to develop into stouter and tougher plants. During this phase of development a good soil mix and decent container size provides all the nutrients they require.
Don't forget to check your water pH with every watering and use cheap vinegar to adjust it downwards instead of mineral salts (to prevent salt build-up). The correct pH is essential for healthy growth! For soil it should range between 6.2-6.5. In hydroponic systems start with 5.6-5.8 on fresh rockwool cubes, or 5.8-6.0 on new expanded clay pebbles if they are not pH neutral. Check the pH of drained water in hydroponics and adjust the pH as required.
Our strains are unique in their high level vigor and fast growth. For optimal plant growth you don't require to perk them up with root stimulators. Our genetics already come with an inbuilt turbo boost. Root stimulators can in some cases be counterproductive. None of these products have been adequately scientifically tested on cannabis by manufacturers!
To support the vigorous growth of our strains you should buy quality soil and choose/adjust container sizes according to the size of the plants. Repot quickly if you germinate in small cups. Rootbound plants quickly develop nitrogen deficiency and other deficiencies. “Rootbound” is a condition which exists when a potted plant has outgrown its container. The roots become entangled and matted together, and the growth of the plant becomes stunted. Rootbound plants can lead to a higher % of males and trigger male flowers on female plants!

If the water has a high EC then you should filter it with a household reverse-osmosis filter and mix this 50-50 with tap water.
Step 3
Do not fertilize in the first weeks of growth on soil! This is the [HASHTAG]#1[/HASHTAG] cause for sick plants. Transplant into quality horticultural grade potting soil and bigger containers as the plants grow larger. Rootbound and sick plants should be avoided. Our plants grow quicker and more vigorously than most other strains. Do not let your good plants vegetate in tiny cups and cramped pots. You can get a high % of males or male flowers on your females if you do not care for your plants properly.
Recommendations
Take advantage of our low prices and plant an extra 1-2 seeds if you don't use the whole pack of 10 seeds. Although we, and the plants, do everything in our power to produce 100% viable seeds please remember this is a biological product. Therefore, even if a seed looks perfect from the outside, it can't be prevented that a minor % of seeds does not germinate, or that the seedling is not completely healthy. That's why it's a good idea to have an extra seed sprouting as a back-up and then you can always select the best seedlings for your grow.
Keep your fingers from those fertilizers and potions. Yes, it happens again and again: growers feeding their seedlings on soil with mineral or biological fertilizers & rooting products, spraying them with homemade teas, or killing them not so softly with harsh biological pesticides. Seedlings are baby plants with delicate young leaves and roots. Let's put it this way: you don't feed a T-bone steak to a baby. Seedlings require 3 weeks to develop into stouter and tougher plants. During this phase of development a good soil mix and decent container size provides all the nutrients they require.
Don't forget to check your water pH with every watering and use cheap vinegar to adjust it downwards instead of mineral salts (to prevent salt build-up). The correct pH is essential for healthy growth! For soil it should range between 6.2-6.5. In hydroponic systems start with 5.6-5.8 on fresh rockwool cubes, or 5.8-6.0 on new expanded clay pebbles if they are not pH neutral. Check the pH of drained water in hydroponics and adjust the pH as required.
Our strains are unique in their high level vigor and fast growth. For optimal plant growth you don't require to perk them up with root stimulators. Our genetics already come with an inbuilt turbo boost. Root stimulators can in some cases be counterproductive. None of these products have been adequately scientifically tested on cannabis by manufacturers!
To support the vigorous growth of our strains you should buy quality soil and choose/adjust container sizes according to the size of the plants. Repot quickly if you germinate in small cups. Rootbound plants quickly develop nitrogen deficiency and other deficiencies. “Rootbound” is a condition which exists when a potted plant has outgrown its container. The roots become entangled and matted together, and the growth of the plant becomes stunted. Rootbound plants can lead to a higher % of males and trigger male flowers on female plants!
