Choosing a stand up soil blocker can be confusing because capacity, block size, seed-pin options, and working height all affect how useful the tool will be. A compact handheld model may suit a small seed-starting project, while a floor-standing press can save considerable effort when hundreds of seedlings are involved.
My first choice is Ladbrooke Ladbrooke Authentic Multi 35 Commercial Soil Blocker England Long. Its 1 1/8-inch blocks suit lettuce, herbs, onions, flowers, and other crops commonly grown in small cells, while the included seed pins make it ready for precise sowing.
My second choice is Ladbrooke Ladbrooke Authentic Multi 20 Commercial Soil Blocker England 20-Cell. Ladbrooke Authentic Multi 20 Commercial Soil Blocker is the alternative for gardeners who need larger 1.5-inch blocks. It produces fewer blocks at a time, but the extra growing medium gives seedlings more room before transplanting and may be a better match for crops that spend longer in propagation.
This comparison covers five soil-blocking tools, from commercial floor models to versatile handheld sets. You will see where each one fits, what its block size means in practice, which accessories are included, and how to choose a tool that matches your planting volume and growing routine.
5 Best Stand Up Soil Blocker
I selected these products by comparing their stated capacity, block dimensions, seed-pin options, construction details, compatibility, and available customer-feedback evidence. The list includes two high-capacity Ladbrooke models plus smaller alternatives so different garden sizes and budgets can be considered without pretending that any product was personally tested.

Ladbrooke Ladbrooke Authentic Multi 35 Commercial Soil Blocker England Long
The Ladbrooke Multi 35 is designed for gardeners, greenhouse growers, and farms that want to make many small soil blocks in one motion. Each press produces 35 blocks measuring 1 1/8 inches on every side, a size that closely matches the needs of crops normally started in 98-cell trays. That makes it especially practical for lettuce, herbs, onions, early mustards, kohlrabi, flowers, and similar plants that will not remain in the greenhouse for an extended period.
Its long handle and floor-oriented design let the operator work from a standing position rather than repeatedly bending over a small handheld mold. Wet potting mix is compressed into the form and released with the ejection handle, creating a fast workflow when a full tray or several trays need filling. The included seed pins form planting holes, with the product supporting either 5/8-inch seed pins or 1-inch dowel pins according to the supplied details.
Made in England from zinc-coated steel, the Multi 35 is positioned as a robust, utilitarian tool rather than a lightweight seasonal accessory. Cosmetic blemishes and water-bathing marks can occur during manufacturing, so buyers who expect a polished decorative finish should set expectations accordingly. Its main limitation is the small block size: plants needing more root room may be better served by the Multi 20.
Pros
- Creates 35 small blocks per press for high-volume propagation.
- Long handle supports standing operation.
- Includes seed pins and works with two stated pin sizes.
- Zinc-coated steel construction is intended for repeated use.
Cons
- Small blocks are not ideal for every crop or long greenhouse stays.
- Floor-standing equipment needs dedicated storage space.
- Cosmetic manufacturing marks may be present.
My Opinion
This is the strongest choice for serious seed starting where speed and small-cell capacity matter more than maximum block size. Before buying, confirm that 1 1/8-inch blocks fit the crops and trays you already use; otherwise, the Multi 20 may provide a more forgiving growing window.
Ladbrooke Ladbrooke Authentic Multi 20 Commercial Soil Blocker England 20-Cell
The Ladbrooke Multi 20 takes the same general commercial approach but creates 20 blocks measuring 1.5 inches by 1.5 inches by 1.5 inches. That difference is important: each seedling receives more starting medium, which can give the plant additional time before transplanting. For gardeners growing a mixture of vegetables, flowers, and cuttings, the larger format may be easier to manage than very small blocks.
A long handle keeps the tool suitable for standing operation, and the ejection handle is intended to release the compressed blocks into a tray. The Multi 20 uses either 5/8-inch seed pins or 1-inch dowel pins. The smaller seed pins are included, while the 1-inch dowel pins must be purchased separately, so buyers who want both planting-hole sizes should account for that extra accessory.
This model is still a production-minded tool, but its capacity is lower than the Multi 35. Twenty blocks per press will take more cycles for a large commercial sowing, yet the larger blocks can reduce the need for an early step-up. The zinc-plated steel construction is built for long-term utility, with possible water marks or cosmetic blemishes that do not affect the stated function.
Pros
- Produces useful 1.5-inch blocks for more growing room.
- Long handle reduces the need to work on the floor.
- Commercial-style construction suits repeated propagation.
- Includes 5/8-inch seed pins.
Cons
- Lower output than the Multi 35.
- 1-inch dowel pins are sold separately.
- May be more capacity than a casual gardener needs.
My Opinion
The Multi 20 is the better Ladbrooke option when block size matters more than maximum throughput. It is a sensible alternative for gardeners who want a stand-up tool but grow seedlings that benefit from extra root space. Check your tray dimensions and handling routine before ordering, since larger blocks occupy more room per plant.
NVRGIUP 4-Cell 2-Inch Soil Block Maker
The NVRGIUP soil block maker offers a more approachable format for gardeners who do not need a commercial floor machine. Its handheld mold creates four 2-inch cubes at a time, giving each seedling substantially more room than the small-block Ladbrooke Multi 35. That size can be useful for larger seedlings, cuttings, or plants that need a longer period before moving into the garden.
Its thickened round handle is intended to spread pressure across the hand and avoid sharp edges during operation. The tool is made from iron and described as sturdy and well built, while the supplied information also says it is easy to clean and resistant to rust. Three different seed pins are included, allowing the user to select a suitable indentation for different seed sizes rather than relying on one fixed hole.
The trade-off is speed. Four blocks per press is practical for a home garden, but it will require many more cycles than either Ladbrooke model when starting a large number of seedlings. The process also depends on moisture: the soil must be properly wet and mixed or the blocks may not form completely. Because it is handheld, the user must supply the downward pressure and keep the mold level during ejection.
Pros
- Makes four roomy 2-inch blocks at once.
- Includes three seed-pin sizes.
- Rounded handle is designed for more comfortable pressing.
- Reusable format reduces dependence on disposable pots.
Cons
- Much slower for large planting runs.
- Requires consistent hand pressure and moisture control.
- Does not provide the standing workflow of the top two models.
My Opinion
This is a useful middle ground for home growers who want large blocks without investing in a floor-standing commercial tool. Its 4.1-star customer rating from 230 ratings suggests meaningful buyer interest, but the handheld design remains the central limitation. Choose it for manageable batches, cuttings, and larger seedlings rather than production-scale sowing.
BL2911 BL2911 Amazon.com KUAFU Soil Block Maker Soil Blocker
The KUAFU soil block maker is aimed at growers who organize seed starting around standard 1020 trays. Its stated output is 105 small blocks measuring 1 1/8 inches on each side, filling a 1020 tray over three cycles. That tray-oriented capacity can help gardeners plan sowing sessions around a familiar greenhouse and propagation format instead of guessing how many blocks a press will supply.
Small blocks conserve bench space and work well for plants that move outdoors or into a larger container relatively soon. The manufacturer also positions the tool for seed starting, cuttings, and transplant preparation. Soil blocks are intended to hold together during movement, which can make transplanting less disruptive than removing a root mass from a conventional pot.
The supplied information does not identify a long handle, floor-standing frame, or seed-pin assortment, so this model should not automatically be treated as equivalent to the Ladbrooke stand-up machines. It does include instructions, and the 1020 compatibility claim is its clearest practical advantage. With only two customer ratings shown, the perfect 5.0-star score is encouraging but too limited to carry the same confidence as a larger pool of feedback.
Pros
- Designed around 1020 tray organization.
- Can create 105 small blocks across three filling cycles.
- Useful for seeds, cuttings, and transplant preparation.
- Compact block size makes efficient use of shelf space.
Cons
- Available customer feedback is very limited.
- Seed-pin details are not supplied.
- There is no stated stand-up or long-handle feature.
My Opinion
The KUAFU earns its place for growers who already use 1020 trays and prioritize organized, space-efficient batches. Confirm exactly how the three-cycle filling process fits your workflow and check whether the package includes every forming component you expect. Buyers wanting a clearly documented standing operation should favor one of the Ladbrooke models.
Jownupp 2-Pack Soil Blocker Set
Jownupp takes a flexible accessory-based approach by combining two handheld molds in one set. The larger tool makes six blocks measuring approximately 2 by 1.8 inches, while the smaller tool makes 28 blocks measuring 0.67 inches. This gives a home gardener two propagation sizes without buying separate products, making the set appealing for both larger seedlings and tiny starts.
The package also contains a seedling tray, six grow tweezers, and three types of seed pegs: square, short cylindrical, and long cylindrical. Those extras are practical for sowing different seed sizes and handling delicate seeds, although the supplied information does not specify the exact hole dimensions created by each peg. The metal construction is described as sturdy and resistant to deformation for repeated use.
Operation is straightforward: mix the soil until wet, place the selected seed peg, press the mold, and use the handle to eject the blocks. The six-block large mold is faster than the NVRGIUP for modest batches, while the 28-cell small mold is useful when many tiny starts are needed. Neither tool offers the standing posture or commercial output of the Ladbrooke models, so larger operations may find the repeated handheld pressing tiring.
Pros
- Two block sizes cover different stages and crop types.
- Includes tray, tweezers, and three seed-peg styles.
- Large mold produces six blocks per press.
- Small mold provides 28 compact blocks per press.
Cons
- Handheld operation is less efficient for high-volume work.
- Exact seed-hole dimensions are not provided.
- Block measurements differ between the two molds.
My Opinion
This is the most versatile value-oriented format in the group because it covers both 2-inch-class starts and very small seedlings. Its 4.4-star customer rating indicates generally positive feedback, but buyers should verify that the included tray and accessories match their existing setup. It is best for varied home propagation rather than a single high-output crop.
How I Selected These Soil-Blocking Tools
The rankings emphasize useful differences rather than treating every soil mold as interchangeable. Output per press, block size, working position, seed-pin availability, tray compatibility, construction notes, and the amount of customer feedback all influenced the order.
The two Ladbrooke products rank highest because their long handles, floor-oriented designs, and commercial capacities are clearly documented. The Multi 35 leads for high-volume small-block production, while the Multi 20 follows because its larger blocks may suit a broader range of seedlings even though it produces fewer at once.
The remaining choices serve different needs. NVRGIUP offers four large blocks with three seed-pin options, KUAFU focuses on a 1020-tray workflow, and Jownupp supplies two sizes plus several accessories. Those distinctions matter more than a simple star score when the tools are built for very different planting routines.
Choose by block size and planting volume first; a higher-capacity mold is not automatically better for every crop.
Customer feedback was considered when available, but the amount varies substantially. NVRGIUP has 230 ratings, whereas KUAFU shows only two, so the numerical scores should be read as one piece of evidence rather than a complete measure of long-term ownership.
How to Choose a Stand Up Soil Blocker
The right tool depends on how many seedlings you start, how long they remain in propagation, and whether you prefer standing work or occasional handheld batches. Before buying, match the block dimensions to the crop and confirm that the tool’s output fits the trays, shelves, and transplant schedule already used in the garden.
- Match block size to crop duration: Small blocks save space, while 1.5- to 2-inch blocks offer more growing medium for larger or slower-starting plants.
- Estimate your batch size: A 35-block press is valuable for repeated large sowings, but a four- or six-block mold may be easier to justify for a small garden.
- Check the working position: Long-handle floor models support standing use; handheld tools require direct pressure and more repeated bending or table work.
- Confirm seed-pin options: Included pins add flexibility, while missing or separately sold pins can change the true cost and usefulness.
- Verify tray fit: A stated 1020-tray relationship is helpful, but block count and tray layout should still be checked against your actual propagation equipment.
Capacity Versus Block Size
Capacity describes how many blocks appear after one press, but it does not tell the whole story. Thirty-five tiny blocks may be ideal for lettuce starts, yet twenty larger blocks can be more efficient if those seedlings would otherwise need to be potted up before planting.
For a home grower, reducing the number of handling steps can matter as much as making blocks quickly. A larger block may use more shelf space, but it can provide a longer window before transplanting. Conversely, small blocks are efficient when the crop will be moved promptly and hundreds of plants must fit into limited space.
Preparing the Soil Mix Correctly
Moisture is the foundation of successful soil blocking. The supplied instructions for NVRGIUP specifically state that moist soil is required, and the same principle applies broadly: a mix that is too dry will crumble, while an overly saturated mix may smear, deform, or resist clean release.
Mix the growing medium thoroughly before loading the mold. The goal is an even texture where the material holds together when compressed but is not dripping wet. If blocks break as they leave the mold, adjust moisture gradually rather than adding a large amount of water all at once.
Keep the mix consistent throughout a session. A batch that begins at the correct moisture level can dry as it sits, producing weaker blocks later. Covering the unused mix between presses can help maintain a more uniform texture.
First-Time Setup and Operation
Start with a clean tray or flat surface that can receive the blocks without shifting. For a handheld model, place the mold on a stable work surface and keep your pressing motion straight. For a long-handle model, position the tool where the ejection area can be reached comfortably and where completed blocks can be moved without bumping them.
- Prepare and moisten the soil mix evenly.
- Install the seed pin or peg that matches the intended seed size.
- Fill the mold completely, pressing firmly enough to eliminate weak spots.
- Use the ejection mechanism smoothly instead of twisting the mold.
- Place the blocks close together in the tray so they support one another.
- Inspect the first batch before making a large run.
The first few blocks are a useful calibration step. If corners collapse, the mix may need more moisture or compression; if the blocks stick, reduce excess water and clean the forming surfaces before continuing.
Using Seed Pins and Pegs Effectively
Seed pins create a repeatable indentation, which is especially helpful when sowing many cells. The Multi 35 and Multi 20 use stated 5/8-inch seed pins, with the Multi 35 also supporting 1-inch dowel pins and the Multi 20 requiring separate purchase of those larger dowel pins.
NVRGIUP includes three seed-pin sizes, while Jownupp provides square and cylindrical peg styles. Because the supplied data does not define every resulting hole dimension, choose conservatively: smaller seeds generally need shallower, narrower indentations, while larger seeds can use a deeper opening according to the crop’s normal sowing instructions.
A seed pin should be seated securely before pressing. Loose or misaligned pins can create uneven holes, and forcing a peg through compacted dry mix may damage the block or make ejection less consistent.
Tray Compatibility and Workspace Planning
Soil blocks are technically pot-free, but they still need support while roots develop. A tray keeps blocks organized, makes watering easier, and reduces the chance of fragile edges being damaged during movement. The KUAFU model specifically references 1020 trays, while the other products should be matched to trays based on their stated block dimensions and output.
Leave enough room to place the mold, store unused mix, and move finished trays. The Multi 35 is efficient when a full propagation bench is available, but its long floor-oriented body also needs more storage consideration than a small handheld tool.
Do not assume that a tray designed for one block size will accommodate another. Small blocks can leave unused gaps in a tray intended for larger cubes, while oversized blocks may press against one another and become difficult to remove without disturbing roots.
Cleaning and Maintenance
Remove remaining soil from the mold after each session, paying attention to seed-pin openings and ejection areas. Dried mix can interfere with clean release and make the next batch less uniform. A soft brush or gentle rinse is preferable to aggressive scraping that could distort edges.
Dry the tool before storage, particularly after washing. The Ladbrooke products use zinc-coated or zinc-plated steel, and NVRGIUP and Jownupp are also described as durable metal tools, but keeping any metal garden implement clean and dry is a sensible ownership habit.
Inspect handles, pins, pegs, and moving parts periodically. Replace or set aside any bent accessory that creates uneven holes. For the Multi 20, remember that 1-inch dowel pins are separate accessories, so store them with the blocker if you purchase them later.
Storage and Long-Term Ownership
Store the blocker where the frame and handle will not be struck by other tools. Long-handle models are more substantial than handheld sets, so a dedicated corner, rack, or shelf is preferable to leaving them in a damp greenhouse aisle.
Keep seed pins and pegs together in a labeled container. The Jownupp set includes several small accessories, and the NVRGIUP set includes three pin sizes; losing one can reduce the flexibility that made the set attractive in the first place.
Before the next sowing season, check that the mold opens and ejects smoothly. A short test with damp, inexpensive mix can reveal a blockage or alignment problem before valuable seed-starting medium and seeds are involved.
Common Mistakes to Avoid
Most poor results come from mismatched moisture, unsuitable block sizing, or trying to make a high number of blocks without planning the handling workflow. A careful first batch prevents many avoidable problems.
- Using dry mix: Blocks may crack or fall apart during ejection.
- Overwatering the mix: Excess water can create soft, misshapen blocks.
- Choosing tiny blocks for slow crops: Seedlings may outgrow the available medium too quickly.
- Ignoring the ejection motion: Twisting or forcing the mold can damage block edges.
- Skipping tray support: Loose blocks are harder to move and easier to disturb.
- Assuming all pins are included: The Multi 20 does not include its optional 1-inch dowel pins.
- Buying by capacity alone: More blocks per press can be counterproductive if the size does not suit the crop.
Make a small test batch before committing an entire tray of seed. It is easier to correct moisture and block size at the beginning.
Which Tool Fits Different Garden Sizes?
A small home garden with a few varieties may be happiest with Jownupp or NVRGIUP. Their handheld formats require more pressing, but they offer manageable output and useful block sizes without dedicating space to a large floor tool.
A gardener who starts multiple trays of small seedlings will benefit more from the Ladbrooke Multi 35. Its 35-block output is aimed at exactly the kind of repetitive work that makes handheld pressing tiring.
The Multi 20 is a better fit when plants need larger blocks or a longer propagation period. KUAFU is most compelling for someone whose workflow already revolves around 1020 trays and who values an organized small-block layout over clearly documented stand-up operation.
FAQS About Stand Up Soil Blocker
What size blocks does the Ladbrooke Multi 35 make?
The Ladbrooke Multi 35 makes 35 blocks per press, with each block measuring 1 1/8 inches on all sides. This size is intended for crops commonly grown in small-cell trays, such as lettuce, herbs, onions, and flowers.
Is the Ladbrooke Multi 20 better for larger seedlings?
It may be a better fit because it creates 1.5-inch blocks, providing more growing medium than the Multi 35. That extra room can help seedlings remain in propagation longer, although the Multi 20 produces only 20 blocks per press.
Can a handheld soil blocker replace a floor-standing model?
It can for smaller batches, but handheld models generally require more repeated pressing. NVRGIUP makes four 2-inch blocks and Jownupp makes six larger blocks, while the Ladbrooke models are designed for higher-volume standing work.
Do soil blockers require wet soil?
Yes. The mix must be moist enough to hold together under compression. NVRGIUP specifically states that moist soil is necessary, and blocks that crumble usually indicate insufficient moisture, inadequate compression, or an unsuitable mix.
Does the Ladbrooke Multi 20 include 1-inch dowel pins?
No. The supplied information says 5/8-inch seed pins are included, while 1-inch dowel pins must be purchased separately if desired.
Which listed tool works with 1020 trays?
KUAFU is specifically described as compatible with 1020 trays and capable of producing 105 small blocks over three filling cycles. Tray fit for the other models should be checked against their block dimensions.
Final Thoughts
For high-volume small seedlings, the Ladbrooke Authentic Multi 35 Commercial Soil Blocker is the most convincing stand up soil blocker choice. If larger blocks are more important than maximum output, choose the Ladbrooke Authentic Multi 20 Commercial Soil Blocker instead; both provide the clearest match for gardeners seeking a durable, standing propagation workflow.
For the final decision, my first two recommendations are Ladbrooke Ladbrooke Authentic Multi 35 Commercial Soil Blocker England Long and Ladbrooke Ladbrooke Authentic Multi 20 Commercial Soil Blocker England 20-Cell. They are the two options I would compare first based on the ranking and buying factors covered above.
