Germinating marijuana seeds. How to germinate cannabis seeds (shot Indoor). Marijuana weed seed germination. Germinating cannabis seeds is the first step in a successful garden. Marijuana seeds can be germinated in a number of different ways. This shot Indoor seed germination method is easy and works quite well. hi i bought 5 WW and 5 skunk #1 ( both feminized and both of them is seedsman ) from attitude and i put them a glass of water to crack… Just curious if it makes a difference as far as if the seed is good or not if it sinks or floats?
How to Germinate a Cannabis Sativa Seed
The following is a successful step-by-step process for germinating cannabis seeds on any budget. Germination of marijuana seeds, cannabis sativa, & pot seeds with minimum failure.
Always be sure that your work area is clean. This includes YOU. Wash your hands every time before working with seeds – it will increase your success.
Germinating Marijuana Seeds
Preparation & Supplies
In preparing to germinate your cannabis seeds whether one or a dozen, make sure you have everything you need and that it is also CLEAN. I use anti-bacterial soap in my garden for myself mostly, I recommend using it for everything (hands, buckets, tweezers, shot Indoores, etc.).
(shot Indoor method)
For our tutorial, we are using a shot Indoor, mineral water at room temperature, and our chosen seed(s). We use masking tape and a black marker to identify our seeds when germinating multiple cannabis strains.
You can use your local water with one caution. Fill a pitcher with your water 24 hours before using it & leave it open. This allows chlorine and other potentially harmful chemicals to escape into the open air.
Cannabis Seed Germination
Half fill your Indoor with mineral water. We have taken a single seed (female), and placed it in the water (shot Indoor). Notice that the seed is initially floating.
We have identified this seed and now we need to put it away in a warm and dark place for 24-30 hours. This allows the seed to absorb water. The seed does not need or like any light yet, but likes everything warm.
The cannabis seed simply needs warm air, moisture and darkness to begin a good germination process.
Keeping a temperature of between 75 to 85 degrees Fahrenheit is excellent for starting seeds. Warm, wet and dark is what they like.
Select a warm spot that stays consistent in the temperature it offers (like on your water heater). We cover our Indoor with a dark cup to keep out all of the surrounding light.
Again, leave this covered and warm for at least 24 hours. This will allow the seed to absorb water, and is an excellent indication that the seed can grow.
The cannabis seed sinks when it absorbs water (24 hours). When you return the next day and uncover your Indoor, you may notice that the seed sank to the bottom.
If it did not, have no fear. Try stirring the water with your clean finger. The seed may have absorbed water and still be afloat by a bubble or dry spot (happens all the time).
How to Germinate
If the seed still floats, you can add some fresh water* and check back again in 8-12 hours. After that, you can still plant the seed, but chances are slimmer that it will take hold (germinate).
I then take a cup of my personal grow mix (soil) that is the same mix I use in my plants through-out their maturity.
I only transplant once, and it’s moved into the same exact grow medium in it’s final container. This prevents additional shock or stress when transplanted.
Each time you change containers or transplant, it will make the plant stress for a week or so.
Use a humidity dome until the seeds break ground (already germinated).
I use a solo cup and slice four slits in the bottom for good water drainage and added aeration. It also makes the transplant very easy.
I carefully place the seed into the soil with the knot side up. I only place it about 3/16″ under the soil surface and water thoroughly. I am still only using water* at this point.
When I water* the soil, it tends to move some soil over the seed. I label my cup and place it in a dome for high humidity and added warmth (shown next to a clone). Position a small grow light above the dome and have the timer the same as your 18 hour garden clock. We want some air, moisture, warmth and light right now.
Lights should remain ON for 16 – 20 hours and OFF for 4 – 8 hours. You are deciding this right now, because changing this light cycle in mid-growth IS stress for the plant – we will control the lights completely. This is the ‘trigger’ for future growth stages. I recommend 18 hours ON, 6 hours OFF once germinated.
Keep the soil moist, but not wet. there is a difference. After my initial watering, I do not water* it again for 2-3 days, and then I am spraying water* over my cup of soil.
Usually, in about 2-5 days you will see the seedling begin to pop out of the soil. I have seen seeds take 11 days, but usually less.
Sometimes, as in this example, the seed shell stays attached while the seedling works it’s way upward and fights to exist.
Cannabis seed curling upward with seed shell still intact.
Spray the leaves with water* for two days to help transition from the high humidity dome. Don’t water yet, just spray them.
Germinating marijuana seeds
Once the seedling has broken ground and I can see green leaves, I remove the cup from the humidity dome. Move your new baby to the nursery side of your garden with the 16-18 hour grow light cycle and circulating air.
As the seed uncurls and begins it’s beautiful life, it will lose the seed case and begin to sprout it’s first leaves.
As you can see, the sprout stretches upward while wrestling with the seed casing to be released (all this work for our smoking pleasure).
As it spends more time under the light, the sprout should be able to shake the seed and begin to form it’s first 2 leaves (cotyledon).You will find that once you have a regiment down that works, it’s fairly easy to germinate your cannabis seeds indoors at any time of the year.
Congratulations! We have now moved from the germination stage to the seedling stage. Patience, cleanliness and good soil products can help insure a high percentage of germination success with your marijuana seeds.
Germinated Cannabis Seed
First Week (Seedling)
Your new seedling is alive and prospering. In our example, you can leave it in the cup for a couple of weeks while it gains strength. It has everything it needs to begin a stress free life. From here we move into the caring and growing of your marijuana.
At times, I plant more than one seed to a cup. Sometimes I leave them both in the cup, and sometimes I separate them immediately after they break ground.
You should now be on your way to some wonderful romance with your plants.
Do not be afraid to “talk to” and raise your youngsters to be strong, vigorous and ‘stinky’ young ladies.
Be careful not to over water* your seedlings. Wait for the top of the soil to get dry and crusty before you consider watering again.
Water* – In this Chapter, the term water relates to mineral water, distilled or bottled water, or house water that has sat in open air for 20-30 hours.
Giving the seedlings a mild nitrogen mixture in your water* will help vigorous, healthy growth at this stage (if your soil does not compensate in this important area). Be careful! They are still young and very impressionable.
Once your seedling has 5-7 growing days in the cup, you can transplant it anytime to it’s larger container. Make this large enough for the life of the plant (I use 5 gallon containers) I never want to run out of room (soil) at the point of flowering.
I recommend water* throughout this process because my soil mixture contains initial nutrients like nitrogen, phosphates, guano, seafood, and more. At some point, you’ll probably develop your own soil too.
seeds directly sinked when i put them into a glass of water
i bought 5 WW and 5 skunk #1 ( both feminized and both of them is seedsman ) from attitude and i put them a glass of water to crack.
however,some of seeds directly sinked as soon as when i put into water while others floating .after 5-6 hours,all seeds sinked and i put all of them into rockwool cubes.
deoes it mean directly sinked seeds are dead ?
Some seeds are simply initially denser (heavier) than others because of an internal greater water content. In other words: some seeds sink immediately, others take time.
:party0044: thanks chunkymunky
i didnt know that ,i was in panic. i am relax now :sun
You are fine. Some seeds sink right away & some dont. The fat round seeds usually always sink. The small ones seem to float. But you can leave the seeds in the water until you see cracks. Just make sure the water is PH’d just right.
Do not keep them in water for more than 24h. After 24h take them out and put them into wet paper towel.
what is the longest you ‘ve left a seed in water before you took it out of the glass blueskies?
I ‘ve seen pics of seeds(floating) with well developed taproot in glass of water but I ve never left seeds for more than 24-36 hrs myself.. I don’t really soak seeds to be honest tho , only old ones or seeds from hard to germ strains. Usually go strait with wet towels or in wet soil.
Yeah, I’ve drowned a few seeds myself.:sad0123:
I use a slightly damp hand towel now, its amazing how little water it takes to germ a seed. Less is more for me on the waterfront, maybe I’m just a clusterfuck when i comes to germing though. Glass of water= mushy seeds for me.
For fresh seeds I soak them in a glass of warm PH’d tap water with a drop of superthrive for 1 Hour at the most!! Then straight into coco or soil. I use tap water because it has a small amount of chlorine in it to kill off any bacteria on the outside of the seed.Great results. ROOT
My friend put a seed in a shot glass with plain tap water and put it in a draw and forgot about it for a week!, was absolutely fine lol. Had a long tap root though.
Seeds soak any longer then 48 hours will likely suffer from oxy deprivation. I use a lil heat and soak over night adn usaully have tails from 12 – 24 hours then I go directly to soil.
It works well with warm to slightly hot water with first droppin seeds. After 24hrs to 36 you may want to change the water. This is one way to gurantee germination! Ive seen people report on the paper towel method but guess what. water is by far the fastest. Do make sure that you store the cup or whatever you choose somewere kind of warm. The water technique sucks in cold temp rooms. to answer your ques Ive started some of outlaw genetics magic merlin and there were just a few that didnt do anything in the water within 48hrs. I forgot about them noticed 4to 5 days later that they had popped and had completely removed the shell off layin at the bottom of the water!
blueskies -with respect, just because your seeds survived 5 days submerged in water doesnt mean it is good advice to do it.
one way that gardeners kill weeds and their seeds is to submerge them in water for a couple of weeks before putting them on the compost heap!
i soak for 12 hours max and then straight into soil. i have lots of books about horticulture and not one of them advises you to germ any type of seeds in paper towel before planting it .
i know that is the most popular way amongst weed growers but a germinating seed is the most delicate stage of plant growth and there is a high risk of some damage to the tiny root hairs by ripping them off a paper towel and planting them.
if i knew for sure that my seeds were really fresh i wouldnt even soak them – just plant them. soaking helps older seeds that have lost some of their natural water content
Does it mean amything when seeds float vs sink?
I don’t think the good egg/ bad egg rule applies here. Never tried germinating my seeds in a cup of water.
Soak them for 24 hrs and plant them sink or float or regardless how they look.
Float or sink they may still grow.
dont throw a non floater away i have a few steps
1- underwater first night on heating pad in dark most split then to soil
2-dont slit then soak under peroxide overnight slit to soil
3-dont slit pour off liquid leave between napkins for abup to a week to split and go to soil
4-dont split after week start scarcification includes sandpaper picking pieces of husk off scraping the little cover over seem off and fanal dont like to do but have done succesfully must be carful not to injur inside has a high success rate is to split with exacto knife at seam easy easy
for finish stages at about 99 5 success rate after step 3 at about 75 % after step 3 i feel like nothing to lose and actually improve percentages step 4 has a lot to do with how i feel but always get better numbers after if i have to go that far
i had always heard that sinkers are the good seeds, takes a while for good ones to sink, usually a few hours
all my sinking seeds have germinated
i dont do float thing at all i use bottom of beer cup about 1/2 of it then trace folded paper towel till it opens like a book cut out put bean in it i have a tarced piece of terry cloth i use one on bottom to hol mois terry on top keeps it below water anyway nekt day if not split take off top terry pour out water leave in moist paper towel on top of moist terry to hold moisture no need to keep misting all the time
