    Ok, so I have had success putting them root down.. its what I have always done. Im no expert but ive grown a couple times with shitty grow rooms, and they have always come outta the ground. But, I was reading a post the other day that said to put it root UP, because the root curls , and it will only have to curl once to make its way down. So instead of having the root down , where it wastes energy curling twice, once towards to "top" of the seed casing, and then down again to the bottom of the pot. u put it root up so it only curls once, downward.

    is this true?

    Im starting to think its true, because after looking closely at a germinating seed, it down infact look like its curling towards the "top" of the seed casing.

    I soak my seeds in water and just throw them any way they land on the soil and cover them. It is good to put the root down.

    thats what everyone says. And also what I believed. But after reading about it , and actually looking at a seed when the root is first coming out. It does look like the seed should be placed root up , as the root looks like its curling down like the post I looked at said.

    Dunno , i never put em in exactly perfect anyway. Anything will work really.

    I see what ya mean about the root curling. I just looked at my sprouts before coming to where i have internet service. When i go home im going to check that out. Mine always grow as well. Interesting thought.

    i just put mine in the pot root up it always works and the plant will grow faster this way

    I used to put them root down. Then read somewhere to put them root up and have been doing it that way since. I think it works better. Makes more sense to me anyway.

    Yea on my first grow i planted root up and they sprouted in less than 1 day. Now this is my second grow and i planted root down and they still havent sprouted and its been 3 days so now im worried :(

    A CUT and PASTE for you all I have read ssen and heard of both up and down

    [​IMG]Marijuana seeds should be placed with the POINTED END UP into a prepared cannabis seeds germination bed or just good soil at a depth of 1/2 to 3/4 inch. The embryo tap root emerges from the pointed (stylar) end and the natural method of growth is for this root to make a turn and grow downward (see the illustration) This bend formed by the downward curve of the taproot is what emerges from the soil and the friction of dragging the cannabis seeds upward helps the new plant to loosen and cast off the seed case when it breaks through the surface. If the cannabis seeds are placed with the pointed end down, the embryo will be required to expend a great deal of its stored energy for twisting and turning to position the tap root when it realizes that it is heading the wrong way (see illustration of germinating marijuana seeds) The seedling will need this energy to exert the forces required to later lift its head (now enclosed by the two halves of the seed case) above the soil, cast off the seed case and then spread its two embryo leaves and begin the life-giving photosynthetic process. This is a critical stage in growth and carelessness in placing the marijuana seeds will exhaust even the most hearty seedling and result in a slow start and a feeble plant in later life. Cannabis seeds should be placed in a small hole at a depth of 1/2 to 3/4 inch. An excellent medium for germination is a mixture of rich humus and fine sand, such as the type used for aquariums. The soil needs a ph of 7.5 to 8.0 and should not be so moist that it sticks to your fingers. If the medium is too moist, the seeds will rot and ferment before they can sprout. A simple test for moisture is to stick a pencil into the soil and if soil adheres to it when removed, then it is too moist. Sort of like when you test a cake by sticking a straw into it to see if it is baked through to the middle. The ideal is not too moist, and not too dry - and be sure that the soil is well-drained. Research has shown that a soil temperature that is at, or slightly above, the air temperature promotes the best survival rates and growth.

    My question is in the wild when plants drop their seeds do the drop them point up or point down think about it
    im not sure it really matters it has to work harder one way then the other but it would only seperate men for boys or should i say girls from woman

    I'm new to growing and i purchased some seeds from a website. My plants are about 2 weeks now and they are about 8 inches tall with the four leaves... I think they are on pace, what sort of things should i do to improve growing at this point? I have them under a hp gro light 24 hours a day. Also what new stages should I be looking for to know their healthy?

    Thank you

    Check out the grow faq at the top of the page. It will tell you what to look for.

    Good info on the seeds. I never looked for how to put seeds in soil. I wondered why sometimes they seem to take off in what seems like hours, other times taking days.
    I'm soaking beans right now, i'll plant point up from now on.

    before i saw this seed position artical i was planting point down i would always get sprout up with helmet on seed husk still on seedling once i started planting point up they seemed to work out of husk before surfacing look at skeeth above think of what im saying and imagine stem pushing split bean upwards ..... hugh what you think

    Hey fellas,

    Pointed end should always be up. You are learning what it took me a while to learn 15-20 yrs ago. Then I had no net & since growing pot was a BIG no no in my small town community, I was very paranoid about trying to find grow books.

    When the root tip pops the shell, it ALWAYS grows straight out at 1st. So it seems, "Hey, that end [pointed] should go down!" Doesn't work that way. That's where the confusion comes in. After the tip pops, it won't be much time before it curves BACK toward the fat end. Cannabis seeds ALWAYS do that.

    So if the fat end is up, the tap root has to do a 'double take' & do a turn around, because with fat end up, the root is heading toward the surface of the soil, not down into it. That costs a bit of time & plant energy. If the pointed end is up, the seed's root tip can do it's thing uninterrupted. It'll go up for a shot distance, then do it's curve toward the fat end & down into the soil & soon will lift the shell & leaves through the soil.

    I have had roots come all the way to the surface of a soil cup or 10 & head back down. Some of the root was exposed to the light, a no no. These took longer for the rest of the seed pod, with the leaves in it, to come to the light. I put a bit of soil on the exposed section of the root & waited. These I only dug up once or twice, as I found there was too much root to make doing the correction myself safe for new sprouted seed.

    Sure, they grew out OK in the end, but it took a few days longer & they were not quite as big as their strain siblings, but they were OK. Cannabis is very forgiving. Boy, I needed it a few times...

    You can have success doing seeds side ways or fat end up. Sideways is a far second best. But for best, less stressful results? Pointed end always up toward the surface of the soil. Less time wasted & seed energy is saved for growing.

    Happy growing! If you disagree, fine. I'm easy. Good fortune to all!

    Yers in the green grow,
