Pucks = Pressed..Substrate..Cakes.
I decided to make this thread to consolidate my ideas on Pucks. I have other puck threads but they were for testing the idea and i've learned a bunch since then.
What the fuck is a puck you ask ? Well ... a puck is substrate material that is pressed into shape. The first ones I did looked like a hockey puck and the name stuck.
They can be pressed into many different shapes and sizes. The basic idea is that you take pasteurized substrate material and place it in a form and squeeze. Here's how I do it:
Things you'll need:
Substrate materials of your choice (choose contam resistant stuff)
Slurry , 9er tek water , LC (any of them)
The first thing I do is to soak my materials. This means an overnight soak for the sub materials that will be pasteurized and a shorter soak for the cardboard.
So now we're ready to start the puck making process. First order of business is to place torn up pieces of the cardboard into the blender of water (you can add things like karo , potato water etc if you want to).
Use pulse mode (the first button) at first in short bursts so that the blender can keep up with pulping the cardboard. It takes a bit of practice to get it right , but becomes old hat eventually.
Every time your done pulping a load of cardboard in the blender dump it into the wire mesh strainer over a pail and let it drain. When its drained a bit dump it into a large bowl or other bucket and repeat.
Keep blending until you are done all your cardboard. Other things that work good for the mix and blend well are newsprint and egg cartons (not styrofoam). When its done clean up any messes and head outside.
Now its time to pasteurize your sub material. For this thread i'm using a 50 / 50 mixture of Coir and Garlic straw chips. Use whatever has been good to you over the years. The quickest way I like to pasteurize is to put the materials in a bucket of the hottest tap water possible , filled halfway. At the same time boil a large pot of water (or a pot and a kettle).
When the waters boiled add it to the half-filled hot water bucket and voila ... 160 F'ish water. Let that sit for 2 hours solid (don't skimp) and drain partially and allow to cool. When the pasteurizing is done take a clean tub and dump it in there. Don't worry about extra water because it will be pressed out later.
Take the cardboard pulp that you made and have sitting in a bucket and dump it on the pasteurized sub material. Mix very well and evenly. Make sure to get the cardboard as mixed in as you can.
Now take a jar of TV's slurry (colonized BRF cake blended in water) 9er tek water , or other spawn and slowly start squirting (or sprinkling) it on to the sub mix. Keep flipping and mixing as you add the spawn.
I made a very thick BRF slurry so I decided to water it down before this stage. This gave me a lot more Slurry. I simply added slurry to a jar of water , shook and sprinkled on the sub mix.
When that is good and mixed you are ready to form pucks ! To do that get a yogurt container and a large glass jar ready. Start stuffing the yogurt container with the innoced sub mix. Use your hands to push on the material and get it really packed in there.
Use the glass jar bottom to tamp and press the material in the yogurt container. Then flip the yogurt container over the jar (jar is upside-down) and start pressing with all your might , both hands. Rotate the container as you press , you'll see streams of water as all the extra moisture is pushed out. Keep pressing until there is not much or no water remaining to run.
You've just pressed your first puck !
Now eject the puck on a clean surface by pressing down on the yogurt container bottom. Plop , out she comes.
Repeat this process for each puck and when you are done make sure to put them in a clean , dark , warm place and don't forget to mark the strain name if you are doing multiples.
Here's some of the benefits i've found with pucks:
- Little to no contams (have'nt had one yet , touch wood)
- Long-lasting and many flushes
- Easy to handle and much less fragile then a cake
- Many sub materials can be incorporated into the mix
- Gives rise to large fruits
- All work can be done open air with no PC
I'd highly recommend pressed substrate pucks , especially when you use techniques like slurry and 9er tek that place mycelium everywhere in and on the puck. You can see growth within 48 hours.
Here's some pictures of pucks gone by. I hope you enjoyed this thread and as always feel free to try this at home.

And now you know what the Puck i'm talking about ...
