Some equipment innovations are easy to spot. Others solve a problem that only becomes obvious once you look inside the vessel.
Hashtek’s staggered wash bags fall into the second category.
The key innovation is built into the bags themselves: each bag has a different finished length, so its bottom sits at a different depth.
That staggered geometry creates natural separation between filtration layers.
The hidden problem with equal-length bags
In a conventional nested wash-bag set, the bags are all approximately the same length. Once they are loaded into the vessel, their flat bottoms settle at the same depth and press together.
The micron ratings may be different, but physically, the filtration surfaces are compressed into the same area. With the bottoms pressed together, there is less open space between layers for water to move.
That crowding can make recirculation, rinsing, lifting, and collection more cumbersome than they need to be. The problem is the bottoms of the bags pressing against one another because every bag is trying to occupy the same depth.
What Hashtek changed
Hashtek created the staggered collection bag system to solve that exact problem.
Instead of making every bag the same length, we vary the finished depth of each bag in the set. When the bags are nested in the vessel, their bottoms naturally land at different levels.
The result is simple:
- The filtration layers remain vertically separated.
- Water has more room to move between the bags.
- Each layer is easier to rinse and work with during collection.
- Separation is built directly into the geometry of the bag set.
The bag lengths do the work automatically.
Hashtek was the first to develop this staggered-length approach for collection bags. It came from looking closely at what actually happens inside a working wash vessel and designing around the physical behaviour of the bags—not just changing the list of micron sizes.
Why natural separation matters
More space for water movement
When equal-length bag bottoms press together, the open space between filtration layers is reduced. Staggering the depths preserves that space and gives water a clearer path through the nested set.
That is especially useful in recirculating workflows, where consistent movement through the bag stack matters throughout the wash and collection process.
Easier rinsing and collection
Vertical separation also makes the individual layers easier to manage. Operators can work one filtration layer at a time with less interference from the bags below it.
The practical benefit is a smoother collection process: easier access, cleaner rinsing, and less fighting with several compressed bag bottoms at once.
Separation built into every bag
The bags load into the vessel like a familiar nested set. Their differing lengths automatically place the filtration bottoms at separate depths, so the advantage is present every time the set is loaded.
Why we replaced the 25 micron bag with a 140 micron bag
The 25 micron bag was the least useful layer in traditional sets. It clogged quickly, slowed collection, and the material it captured was usually poor quality. Many hashmakers threw that collection out rather than mixing it with better grades.
Traditional sets also leave a wide gap between 120 and 160 micron. Replacing the 25 micron bag with a 140 micron bag puts a useful collection point right in that gap.
That gives hashmakers a more practical eight-bag progression and another meaningful grade to inspect, rinse, and collect—instead of a bottom bag that often became a bottleneck.
The micron configuration is a practical improvement, while the larger innovation remains the staggered geometry that creates natural separation throughout the complete bag set.
Available now in 20 gallons
The 20-gallon STAGGERED Collection eight-bag kit is available as a complete set.
Individual 20-gallon staggered replacement bags are also available across the micron range. That means you can replace a worn bag without purchasing a complete set or build a custom stack around your cultivar and workflow.
There are no tariffs or duties on any bags we sell.
44-gallon staggered bags are coming soon
The staggered system is growing. Hashtek is preparing a 44-gallon version for larger-scale workflows, built around the same principle: different bag lengths keep the filtration bottoms naturally separated throughout the stack.
We will share full specifications and availability when the 44-gallon system launches.
A better bag set starts with the space between the bags
Micron selection matters. Mesh quality matters. Construction matters. But the physical relationship between the bags matters too.
When every bag is the same length, the bottoms press together. Hashtek’s staggered system builds separation directly into the set, creating more room between filtration layers and a cleaner, more practical workflow from recirculation through collection.
For a limited time, use code STAGGERED15 for 15% off eligible 20-gallon staggered wash bags through August 25, 2026.
