Cannabis seed cracker tool

The Seed Cracker

First, I want to thank Lester Beans for his thread and mention of cracking seeds, and that someone made a device to aid with this. And big thanks to Thailer for following up with details.

I have never been too keen on the idea of scuffing. Can’t remember now the member here who recommended using nail clippers to clip the very end of seeds to help with germination, but I liked it. And cracking even more so. I have more than a few packs of seeds in the vault that may not be viable. Here’s a short list off the top of my head without actually looking.

G-13 IX
Dutch Dragon
Thai Tanic
Schnazz #2
Ancestral Skunk #1 (known to have around 10% viability)
Thai Lights
Bubble Gum
BOG Bubble
Sweet and Sour Cindy
Critical Romulan

I ended up buying “The Seed Cracker” to hopefully improve the possibility of getting these older, questionably viable seeds to pop. I have other projects and fresher seeds I had wanted to be popping next but I really need to shelve those plans to work my way through these seeds to see if anything can be saved from them. I will pair them with similar lineages when possible. For example, when I try to pop Thai Lights I will follow that up with Thai Tanic if results are poor. So maybe I get two girls from TL and only one plant, a male, from TT. I will toss some pollen around. Likewise, Afghanica and Exile will pair as both are basically Afghan Skunks (Afghanica more so than Exile). And Bubble Gum with BOG Bubble, etc. If I have a high germ rate – 70% – or above on any pack, I will work with those first before popping a similar counterpart. My goal is to try to produce fresh seed stock from each, but depending on viability it may end up as crosses that attempt to stay within similar familial lines. I have two packs of G-13 IX and will start with it. Depending on the results, that may be it until July. If no luck with G-13 I will try to start the Thai crosses next. All this will be to gear up and get practiced before July, when I plan to try to pop 75 AS #1 beans. This will tie me up for some time as I work my way through these packs. I will use this thread to document the results.

The Seed Cracker cost $55 and $10 shipping within the US. For an additional dollar per letter, up to 16 letters can be stamped on it and/or for three dollars a cannabis leaf. Kind of pricey. Especially when you consider that you could get this from Amazon for less than $15.

Mill out a nesting bed right in the center, mount it to a board or something else so as to fix it into an upright position, and get cracking. Looks like it would work… ?

Here’s my Cracker:

When I was looking around online to see pics of it I found this video of it in action:

I am going to get some GA3 to see if it improves chances. I plan to prep five beans of G-13 as shown in the video using GA3. The other five I will prep with a variation of Chimera’s method as well as soak after washing. I found the claim in the video of gravity aiding by taping the baggie to the cupboard door to be, questionable. Anyone think that makes sense? I suppose it couldn’t hurt and would also allow excess solution to drain away.

Cracking seed shell with pliers

I had some seeds that I was trying to germinate but nothing happened for like 4 days. These seeds have been in a moist paper towel in my closet for 4 days and nothing happened. No white tap root. So I figured that I’d take my chances and take a pair of pliers and split the shell manually for the seed. Then I put them back in the paper towel. I work up this morning with tap roots showing! Little ones because the seed just recieved moisture. Hope this might help someone in the future!

thats risky man. you shouldnt even touch the tail that comes out with your hands. cause of the oils you got in your skin.
it may turn out half cannabi half human

I used tweezers to make sure that i didnt cross-breed the plant with myself. They are actually growing quite fast. Faster that my last seeds. One has already dropped its shell and the others are on their way. This was a neat little technique. I cracked 2 out of 4 seeds that i had and the 2 cracked ones germinated while the other 2 had zero progress.

after i wait for like seven days i get into scarcification of seeds i feel like ther is nutin to lose and sumtin to gain
most tmes it improves rate of germ
i normally split at seam wit razor crack off pieces of shell and sandpaper sumtimes i try all kinds of tricks i might try plyers next time

whatever technech you use try not to damage the inside embrio of seed
good luck

Another trick is to peel off the shell at the pointed end of seed. The taproot can then come out easy. As was said, whichever way you go, do not mash or cut the insides of the seed.

If you scrape the outside seed coat with a knife or sandpaper is increases the chances of water absorption and germination. Pliers seems a bit extreme but if it worked it worked.

The Coral Reefer

They have germinated and the cotyledon opened and was green by the time i turned the lights off tonight. This morning they were white. Much progress! I didnt have anything to lose and i took a chance and it paid off! Thanks for all the tips and tricks! We need a thread for tips and tricks or does one already exist?

Well-Known Member

lmao!! Thanks, that made my morning!

Actually what you’ve done is re-discovered an old time technique. As someone else said too, scuffing seeds w/sandpaper also works well. The trick is to make it easier for moisture to get to the inside of the shell casing.

i just had a seed germinate after a month of sitting in paper towels on a plate on my cable box. i might try “helping” a few of the seeds that haven’t popped yet.


I need some help.I got some lowryder from attitude n I’m on day five of the paper towel germination n there showing no signs of life. I’ve done this before n Its never took more them three for me.I may have put a little to much water once or twice but I don’t think I killed them.has anyone had there seeds take this long or have any advice on how to speed this process up,cause its slowly killing me on the inside

The Coral Reefer

Yeah this same thing happened to me so I figured that i would take my chances and experiment. I actually did this to a lowryder 2 seed and she is growing nicely. Im growing them right in my living room.

If they don’t germ in paper towels, put it in soil with saran wrap or a dome over it, with light and keep it moist. That worked for two fem seeds we ordered that didnt do anything in the paper towels.

Sometimes you just gotta up the temp. To get them to crack. I think 77f is good distilled water but i do get out my tweezers alot just to help em out a lil get the leaves showen, after there cracked though.

Ok first and foremost, killing them with a little to much, well first you woulda seen a taproot, i mean the shell needs to soak up water, and then a tap comes, so to kill them unless they are rotted or mushy you didnt kill them odds are the just are hard ass shells and havent received enough water.

I am having issues with popping ATM I had like 6 or 7 from this batch i have pop just fine now the next 10 literally are like all 3-5 days inside with warmer temps and no popping, I cut into 2 just to see, inside you can see the baby bundles and tap developed slightly. This makes me wonder if the bun in the oven just takes a tad longer or maybe the shell was 2 hard and towel not wet enough.

Right now i am messing with bag seeds cause I dont wanna fuck up my nice attitude seeds until i have a pretty solid system down.

We all have our own plans and ways, I am gonna try a light scoring with a razor blade or scalp, not deep just a light score along either the sharp edge, or maybe a couple over the rounded top and bottom edged on some of these bags seed see if it helps take in some more water and crack. Seeds have some stored energy which is there to help a tap and base leaves develop. but if they use it all breaking the shell they cannot then push to set the tap and break the earth/soil/medium. NO BUENO. ( Learn this farming ** not bud btw real farming ** since I was a child so over 20 years. )

Also the soaking in water can be good, it can do some harm if your tap water or whatever has toxins in it. I perfer like Arrowhead or other Mt. Spring water, they have no chem and good trace minerals.

Also the towel has to be wet, I mean soaking wet, not dripping but soaking, you do not want a puddle but moister, it helps it soak through the shell and makes it easier for the tap to absorb.

Hum what else. I have bad luck on my last batch of 10 first time in years, my guess the towels were not wet enough and I may have had toxins on my fingers or the shells where to hard.

I am going to try cracking or scoring but cracking sounds a tad risky with $10 a pop seeds to me. ‘
