<p>Spring is in the air, so its time to plant some seeds and grow some veggies!</p> <p>Soils blocks are an excellent way to sow seeds indoors or in the greenhouse to prepare for planting outside. You don't need a lot of plastic pots, can quickly plant a lot of seeds, and most importantly, plants in soil blocks don't get root bound like they do in pots, so get less transplant shock once you plant them in the garden.</p> <p><br/></p> <h5>This set contains three different size blockers:</h5><ul> <li><p>5x5x6 cm soil blocks with a dimple on top for the seeds<br/></p> </li> <li><p>Small 3.5x3.5x4 cm soil blocks for smaller seeds.</p> </li> <li><p>Micro 1.8cm soil blocks for germinating seeds indoors that will be planted out directly into the garden or<br/></p> </li> <li><p>Screw the square form in the large blocker and make blocks with a large hole that you can fit the micro blocks into if you want to keep the seedlings indoors for longer<br/></p> </li> </ul> <p><br/></p> <h5>How to make a soil block:</h5><ul> <li><p>Make a fine potting soil in a bucket. You can mix your own but store bought potting mix also works fine. make sure there are no big pieces of wood or fiber; you could print a sieve if needed<br/></p> </li> <li><p>Water the soil thoroughly. The soil needs to be really wet but not muddy. If you can make a ball in your hand that keeps it shape, and if you can squeeze water out the ball with your fist its good.<br/></p> </li> <li><p>Fill the blocker by pressing it into the soil, or with your hands until it is completely full.<br/></p> </li> <li><p>Put the blocker in a shallow tray, press the plunger to compress the soil a bit extra, then raise the mantle while keeping light pressure on the plunger. You should press quite hard, the block should have well-defined edges.<br/></p> </li> <li><p>You now have a soil block! Seed it, lightly cover the hole with some extra soil if needed. The block needs to be watered after about two days.<br/></p> </li> </ul> <p><br/><br/><br/><br/> Updated: added mini-blocker, changed microblocker clearance and added flanged nub (should release better)</p> <p>Icon made by Freepik from www.flaticon.com</p> <h3>Print instructions</h3><p>Files print in-place without extra supports. tested at .3 mm</p> <p>Included Gcode prints the complete set, with the 'ears' attached to the large blocker to help against the thin wall lifting. When printing the files separately you can add the ears to the corners or add a brim.</p> <p>The microblocker prints up-side down as in the STL, after printing remove the breakaway supports. Make sure thin line and perimeter bridge detection are turned on.</p>
