Making dry sift comes down to three things: the quality of your starting material, the mesh sizes you run it through, and how gently you work the flower. If you are shopping for equipment, buy a multi-screen set (about 150, 120, 90, and 73 micron stainless mesh) instead of a single-screen shaker box. A three or four screen stack lets you grade and clean resin in one pass, and that matters far more than the name stamped on the frame. Skip solvent kits, presses, and anything marketed as a shortcut until you can pull clean sift with plain screens.

What You Need Before You Start
- Dried and cured flower or trim that has been chilled in a freezer for at least an hour
- A set of stainless screens or a sifting box with swappable mesh
- A cold, dry space, ideally under 70 degrees Fahrenheit
- Parchment paper, a silicone mat, or a glass collection tray
- A stiff plastic card, a soft brush, and nitrile gloves
No press or solvent is required. Dry sift is a mechanical process, so your only consumables are plant material and the screens themselves. That is why screen quality is the one place worth spending on.

Screen Sizes and What They Catch
- 150 micron: First pass. Removes stems, leaf fragments, and large debris while letting most resin heads through.
- 120 micron: Working grade. Good yield with a small amount of plant matter mixed in.
- 90 micron: The sweet spot for most home growers. Clean resin with decent yield.
- 73 micron: High grade. Mostly intact trichome heads and very little green material.
- 45 micron: Full melt territory. Slow to collect and easy to clog, so treat it as a bonus screen.
Step by Step
- Chill your flower in a sealed bag or jar in the freezer for one to two hours. Cold resin turns brittle and releases from the plant more readily.
- Work in a cold room. Set your screens on a clean surface with parchment underneath the bottom screen.
- Load the top screen with a loose, thin layer of material. A heavy pile pushes plant matter into lower grades.
- Move the flower around with your card or gloved hand. Use soft, circular passes rather than pressure.
- Collect from each screen separately and label the grades. Keep them apart for storage.
- Clean your best grade by carding it across a finer screen a second time. This removes residual green matter.
- Store in a glass jar in a cool, dark place. Refrigeration slows terpene loss.
What to Look For in a Dry Sift Kit
- Mesh material: Woven stainless steel holds tension better than nylon and does not stretch with repeated use.
- Frame fit: Stacking rings should seat snugly with no gaps where material can escape.
- Micron coverage: A set spanning 150 down to 45 micron handles almost every home setup.
- Replaceable screens: Swappable mesh costs more upfront and less over the life of the kit.
- Surface area: Larger screens process more material per pass but need more freezer space for chilling.
Ask a budtender at a shop you trust about local strains with heavy trichome coverage. Dense, resinous flower produces more sift per ounce than fluffy sativa flower, and the difference shows up fast in your yield.

Common Pitfalls
- Running warm flower. Heat makes resin sticky and smears it into the mesh.
- Using a grinder or blender first. Breaking the plant releases chlorophyll and plant fibers into your sift.
- Pressing hard. Pressure crushes resin heads and drags green material through.
- Overloading the top screen. Thin layers always produce cleaner grades.
- Ignoring humidity. Above 60 percent relative humidity, static and clumping ruin your cleanup pass.
FAQ
What is the best micron for dry sift?
For most home setups, 90 micron gives the best balance of purity and yield, with 73 micron as an upgrade for a cleaner, smaller batch. Start with two screens before buying a full stack.
Can I use trim instead of flower?
Yes, and trim is often the better choice since it would otherwise be discarded. Expect lower yield and a slightly greener result than whole flower.
Do I need to freeze my material first?
It helps a great deal. Chilled resin separates more cleanly, and the difference is obvious on the first pass.
How much dry sift will I get?
Yield depends on trichome density, freshness, and technique. Well grown, resin-heavy flower returns more than average flower, and trim returns less than both.
Is dry sift the same as kief?
The terms overlap. Kief usually refers to whatever collects in the bottom chamber of a grinder, while dry sift is a graded product separated by screen size.
Is making dry sift legal where I live?
Rules vary by state and country, and home production of concentrates is treated differently from possession of flower in some places. Check your local law before you start, and keep all products away from minors.
