Seedling is growing upside down, taproot is above the soil!

Is your cannabis seedling growing upside down? Has the tap root come above the soil?

If your root is growing straight up like in the picture below, it’s not good. This is most common in seedling plugs. The tender white root tip has a good chance of drying out or being exposed to too much light. You want to strongly consider doing some “plant surgery” to turn this little seedling around to the right direction

The first thing to do is get a new Rapid Rooter. Since your seed already has a relatively long root, cut the plug open lengthwise so you can gently place the seedling inside in the right position without having to “push” down on the seed.

Now gently extract the seed from its original home with a pair of tweezers making sure to touch only the shell and not the root (the root is the most sensitive part)! Now lay the seedling in the middle of your newly split open Rapid Rooter and gently close the plug around it again.

Most seedling plugs will go back into place easily, and you’ll barely be able to tell it’s been opened

Since your seedling has already sprouted and has been in placed into the right growing position, it’ll probably pop its head out within just 12-24 hours! Sometimes you see just the leaves, but occasionally you actually see the seedling push the shell above ground.

When this happens the shell usually falls off on its own as the seedling grows!

When Should I NOT Do Surgery?

Sometimes you can see the young taproot of a cannabis seedling but the situation isn’t as dire. If the root is already pointed in the right direction, it’s probably going to be just fine! But if you’re worried, you can cover up the root until the leaves actually make it to the surface.

For example you could tear a tiny piece off the edge of this Rapid Rooter and gently lay it on top. Or if you were in soil you could sprinkle a tiny bit of soil over the seedling. The seedling will push it off as it grows upward.

This case isn’t so bad because the root is already facing down, in the correct direction. Note: This seedling was just watered, but typically the Rapid Rooter should never look this wet. It should be moist but not shiny.

If you leave it alone, the seed will start to rise up, and open to reveal the seedling’s cotyledons (first, round leaves)

The cotyledons unfurl and then the regular cannabis leaves between to grow. Here’s another view of that same seedling from above only a few hours later. Even though it may have looked a bit weird at first, this seedling is completely normal and will grow just fine from now on!

Most of the Time Seedlings Take Care of Themselves!

When you see your seedling looks like this, where the part of the root exposed to the surface already looks green like a stem, you don’t need to do anything.

After germination, the tip goes down and stays white, and the other side that’s contained in the shell tries to work its way up, and that part of the stem turns green. Sometimes it looks like the root is going upside down because it appears that it’s not strong enough to be able to push the seed up.

As long as the tip of the root stays wet the seedling will be fine! The “root” is the same as what is going to become the stem. If it appears green it means that part of the root is already in “stem” mode and isn’t sensitive to the light.

If you just wait a little everything will have righted itself Here’s that seedling 12 hours later…

12 hours after that, the leaves have completely emerged!

If you hadn’t been watching you wouldn’t even have known anything happened!

Putting seeds in soil , root up , root down.

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.

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 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.

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

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?

Seed Germination & Planting

Hi Cori, thank you for writing us! Your question is pretty simple to answer, but sometimes not so simple to do! In short, yes, most growers tend to germinate seeds before planting them into their grow medium of choice.

To be clear, however, germination of seeds is not necessary prior to planting in medium. You can sow seeds directly into the medium and they will also germinate there, but not always with the same success rate. The reason growers choose to germinate outside the grow medium is because it is easier to control the conditions surrounding the seeds. This leads to the second part of your question, which is the best-case practices for germinating seeds – this leads to the harder answers.

There are many different ways to germinate seeds. Probably the best methods involve keeping the practice as natural as possible. The simplest methods use water, warmth and darkness – all conditions the seed would naturally encounter underground. Many folks simply lay some seeds down on a paper towel on a flat plate, cover them with another paper towel, then moisten the paper and place the plate in a warm dark place. A popular hiding spot has always been on top of the refrigerator, while more professional growers employ heat mats that lie flat beneath seedling/ clone trays. Heat mats are an excellent and inexpensive aid for seed germination. Whatever you decide, the temperature should be 10-20 degrees above room temperature, or range between 78 – 90F.

Of course, there are always the tricky strains or the old seeds that are quite fussy and refuse to pop. These seeds require a bit more attention and creativity. Some people prefer to soak the seeds for a short period before placing them in a moist and warm place for germinating. Some people go as far as to use mild chemical solutions to help soften the shell and prod the seeds. Other growers will even use very sharp and sterile razors to carefully slice seed shells or tips to help induce germination. These practices are all risky and should only be used as a last resort.

Once a seed cracks open, the taproot appears. This taproot will become the plants primary root from which all other roots will grow. Technically, the seed is germinated once you can see the white of the taproot. Some grows prefer to wait until the taproot is 1-2 cm long before planting the germinated seed into a medium. Once you are ready to do so, be sure to place the seed about a half-inch below the surface of the medium with the taproot point downward and the seed shell on top. Be sure there is some space for the seed shell to push upwards through the medium, towards the light. At this point, the very young seedling still needs moisture, warmth and a bit of light now to direct its growth in the right direction. The seedling will likely be in this medium and container for a few more weeks before the seedling is ready to be transplanted into a larger container for vegetation.

Thanks for reading everyone and remember: Grow… And help the world grow, too!
