  2. Hey Jack, I was wondering how to get the MSB discount at the Soil Cube Website?
    Thanks! Greg

      1. Log into the MSB

      2. Click on “The Soil Cube”

      3. Follow the instructions there


  3. I get so much info from your podcasts. A family member started me on them last fall and I try to get in several a week. My son is now hooked and getting himself on board in many things. Making me very proud of him.

  4. Jack,

    I recently purchased ‘Seed of Change’ seeds from North Haven Gardens in Dallas, they told me they were having the same issues with the company as you, plus they were not getting their seed orders in a timely manner, if at all. They suggest there are issues with this company and that they might not remain in business much longer.


    • Got my soil cube early this week! Got so excited I forgot to post back here! This thing is COOL! I have a ridiculous number of soil cubes prepped for seeds for this weekend!

  5. Mine arrived. I think it took about 8 days or so. He is a one man operation.. I think a lot of people ordered after this podcast. Good job jack!1

  6. Got my soil cube maker a few weeks ago and have been busy with it. My comments:

    The recommended soil recipe didn’t work well for my first batch. I ended up with hard bricks, but my pole bean starts did good in them anyway. Smaller plants may have struggled with it. Now I mix the components by feel, and have a good idea what it should feel like when I compress the wet mixture in a fist and release it. What works better for me seems to be less dirt and more peat. Oh, and the instructions say “wet like oatmeal…” Perhaps Clayton eats really really dry oatmeal, but what I know as oatmeal consistency is too wet. A bunch of water will squeeze out when you compress the cube, it will be muddy and dry to a hard brick if it’s that wet.

    Yes, the roots don’t seem to come out the SIDES of a soil cube, but they most definitely will come out the bottom, big-time. I had my pole bean cubes in the Sterilite tray as Jack recommends… this definitely makes it super easy to water the cubes from the bottom with about 1/4″ of water. After 10 days my beans were 3″ tall and I saw no roots… however, what I found when I pulled them out of the tray is large super-well developed root structures out the bottom of the cubes up to 12″ long! I would have seen them if I had looked up through the bottom of the translucent tray. Needless to say, they were tangled and I lost some of them trying to pull them apart. Some had even started growing into adjacent cubes.

    My soil cube tool has large spaces between the aluminum paddles and the plastic forms. This allows a lot of soil mix to get worked up into the recesses of the tool during production, and if you don’t notice it and keep the tool clean every cube will end up a little smaller than the previous one until they are very short. It’s a pain to get that soil out of there without disassembling the unit. I’m gonna make better fitting paddles for mine and find out if there is a good reason for such a sloppy fit.

    Oh, and use a light touch when compressing the soil cubes with the tool. Develop a soil recipe that holds together well with light pressure and just enough water.

  7. To be clear, my cubes were not floating in water. When they’re dry enough to justify watering, you add about 1/4″ of water, and it sucks up into the cubes in five minutes or so. Super convenient. Does this in itself promote excessive root structures outside of the cubes? Is there a better way?

  8. Oh, one more idea you might not think of right away… if some of your cubes end up too short, or if you simply want taller ones, just stack two of them when they’re fresh and wet! Simple and works great.
