Which seeds float? Male or female?

[AdaminCO]

Lol. That's funny.

I'm impressed that I still have intact memories. That was a while ago.

I can’t remember yesterday, but can remember stuff from 30 years ago.

Don't think that was the H202. H202 breaks down with the introduction of light. By the time yours sprouted it had already broken down into it's separate components of H20 and 02. It usually happens in about 24 hrs.
@InTheShed had some seeds sprout in the cups and he doesn't use H202 iirc.

I use lots ( 1:1 with H20) of H202 every time I sprout my seeds and I have never had one sprout in a cup like that before.

Wait, 2004, 2014, Saturday? Let's do the time warp again!

I do a mix of 50/50 H2O2 and distilled water for 15 minutes before I dump that and soak in just distilled for the rest of the time. Got that from Van I believe. But I haven't seen a difference between with and without.

This is from the EPA (from a prior era):

What is the half life of hydrogen peroxide?
24 hours

The average degradation half-life for hydrogen peroxide in the atmosphere (from different atmospheric conditions) is 24 hours. The direct photolysis degradation of hydrogen peroxide to generate two hydroxyl radicals occurs with a half-life of 2.14 days.

Ah. I was only half wrong.

After reading this thread I have to ask myself .... "Will the growers 10 or 20 years from now read our stuff & get a good laugh as we just did ?"

... half wrong - isn’t that like being a little bit pregnant??

They all float starting out, probably due to surface tension and oils in the seed casing. After 6 to 8 hours if they don’t sink voluntarily I push mine to bottom as many others do. Think nivek recently said he was just germing all his beans as floaters right on the surface of the water.

my seeds always float soon as they hit a cup of water I cover with a paper towel and force the seed to the bottom and let it sit for 12 hours then take the paper towel out and the seed stays submerged for another 12 hours then right into a damp towel on a heat pad until tap root sprouts

Theoretically, seeds could last indefinitely in the right environment like the Svalbard Global Seed Vault in Norway. They keep Landrace strains in their catalog to preserve Cannibus genetics there along with a lot of other stuff.

Focusing on the buoyancy of seeds would be like a purebred hog breeder focusing on the size a dog's balls.

So, you have your beans in your hand. Now you are wondering what you are gonna do to get these to start growing. If you have purchased seeds from a reputable seed bank then you can be sure that they are all fit to attempt to germinate since they have been through a screening process already. However, if you have obtained your seeds from a bag then you need to do some simple checks to see if the seeds are viable or not. One way to test yourself is to lightly squeeze the seed between your index finger and thumb. If it gets crushed, then it's no good. Usually white, dried up seeds are immature and will crush. Dark green, green or brown seeds are more apt to germinate well. You can't tell the sex of a plant by looking at the seeds. The are some theories here but there are no physical signs that one can use to distinguish male from female seeds.

Some people like to germinate the seed using methods such as the paper towel method before they grow the plant. This is to ensure that the seed(s) get off to a good start . But it is not really necessary to do this unless you have a large amount of seeds for your area (50-100+ seeds). If you only have a few seeds then you can plant them right in the soil.
To germinate in a paper towel simply place the seed between to dampened pieces of the paper towel. Next, place the seed/towel combination into a Tupperware container or plate. Set the container on top of a computer monitor, refrigerator or propagation pad and wait until the seed cracks and you see a tiny white root tip start to emerge from the seed.

After you have germinated the seed you will see a little white root sticking out of the split shell. Dig a small hole in the soil (I like to use the end of a pencil to make the hole). When planting the seed(s) or sprout be sure to only go down 1/4" to 1/2" and drop the seed in. Make sure that the root or pointy side of the seed is pointing down when inserting into the soil. Fill over the whole with soil, then keep the soil moist but not damp/wet with some water. You should provide at least 4" of vertical space for the tap root to grow down. Place one seed each in a 20oz+ cup or a one gal pot then place your pot under your lights. Start with a 24/7 light cycle (24 hours on, 7 days a week). You should see sprouts within 2-14 days depending on your individual conditions and the method you used. For quickest results try and keep the temperature in the mid to high 80's (F). You will see slower germination rates but lower temperatures are acceptable as well (70s), this will simply increase the amount of time it takes to germinate the seed.

The sprout will emerge first with the 2 seed leaves. These leaves are small, smooth and round followed by a set of single bladed, serrated leaves known as the first leaves. The height of your light from the sprout will depend on what kind you are using. If using florescent lights, they usually run cool enough to put them within 1-2 inches of your sprouts. If your going with a HPS or MH type of light, they get hot, so you won't want them too close. A good way to test a light is to put your hand between the plant (or in this case soil) and test how hot it is with your hand. If it's uncomfortable for your hand, it's too hot. Raise the light up until you reach a good temperature. These type of lights will also dry your soil out fast, so keep your eye on it. Once your light is set and the leaves start coming in you now are on you way to growth stage.

Once you see the plant break though the top of the soil (it should take from 1 day to 1 week) you will see two small round leaves. Your plant will grow up a few inches with the two leaves getting a bit bigger and new leaves starting between the two round ones. Your stem will probably look white, green or even purple at this stage. The color depends on what strain of plant you have. It's advised that you refrain from giving your plant fertilizer during the first stages of growth. These stages are quite delicate, it doesn't take much to make a fatal mistake. Remember though out the whole live span of your plant, like most other things in life, the more things you have going on at one time, the more likely for a problem to arise. Your best bet is to keep things simple

Very well written and very informative.

wich seed float male or female?~!

Remembering back to the last time I had sex in the hot tub ... I'd have to say ... 50/50.

 

[little kitten]

The ones that float are bad the ones that sink are good. Simple as that.

ALL mine float. And I know they're good, cause 2 already came up

 

[Schedapirata]

I just popped 30 year old seeds from my collection. Both floaters and non foaters sprouted. The ones that didnt pop when lightly squeezed. Let see first what they are and then how they compare.
