Cold makes trichomes brittle — Ice water causes the resin glands (trichomes) to become stiff and snap off easily
Agitation separates trichomes — Stirring or mixing breaks trichomes free from plant material
Trichomes sink — Being heavier than water, they fall to the bottom
Screens filter by size — Multiple mesh bags catch trichomes of different sizes while letting plant matter through
The result is pure trichome heads — the part of the plant that contains cannabinoids and terpenes.

Choosing Your Starting Material
The quality of your bubble hash depends heavily on your starting material:
Fresh Frozen (Best Quality)
Cannabis that’s frozen immediately after harvest produces the best bubble hash. The trichomes are preserved at peak ripeness, resulting in:
Maximum terpene preservation
Lighter colour (blonde to gold)
Superior flavour
“Live” hash designation
Dried and Cured Flower
Quality dried flower like Black Diamond or Bubba Kush makes excellent bubble hash. While not quite as terpy as fresh frozen, it’s more accessible for home producers.
Trim and Shake
Sugar leaf trim works great for bubble hash. It’s economical and produces solid results, though yields and quality will be lower than flower.
Pro tip: Whatever material you use, freeze it for at least 24 hours before extraction. This makes trichomes more brittle and easier to separate.
Step-by-Step: Making Bubble Hash
Step 1: Set Up Your Bags
Place your bubble bags inside the bucket, largest micron on the outside
Common order (outside to inside): 220µ → 160µ → 120µ → 73µ → 45µ → 25µ
The 220µ “work bag” goes in last — this holds your cannabis
The bags filter from largest to smallest micron. Plant matter gets caught in larger screens while pure trichomes pass through to smaller screens.
Step 2: Combine Ice, Water, and Cannabis
Add your frozen cannabis to the work bag (220µ)
Add enough ice to create a 1:1 ratio with your cannabis
Pour in cold water until everything is submerged
Add more ice on top
Let it sit for 15-20 minutes to get everything cold
Temperature is critical: Water should stay between 32-40°F (0-4°C). Add more ice as needed throughout the process.
Step 3: Agitate
Using your paddle or spoon, stir the mixture vigorously
Mix for 15-20 minutes for the first wash
Use a circular motion, occasionally changing direction
Be thorough but not aggressive — you want to break trichomes free, not shred plant material
If using a washing machine, run it on gentle cycle for 15-20 minutes.
Step 4: Drain and Collect
Let the mixture settle for 15-20 minutes after agitation
Slowly lift the work bag (220µ), letting water drain back into the bucket
Set the work bag aside (you’ll reuse this material)
One by one, pull each bag out of the bucket
Let water drain through, then use a spray bottle to wash trichomes to the bottom
Scrape the collected hash from each bag onto parchment paper
Label each collection by micron size
Step 5: Repeat (Multiple Washes)
One wash doesn’t get everything. For maximum yield:
Put the work bag back in the bucket with the material
Add fresh ice and cold water
Agitate again (you can be more aggressive on later washes)
Collect and separate each wash
Typical wash schedule:
Wash 1 (15 min) — Highest quality, most terps
Wash 2 (15 min) — Still excellent quality
Wash 3 (20 min) — Good quality, slightly darker
Wash 4-6 (20 min each) — Decreasing quality, darker colour
Step 6: Dry Your Hash
Proper drying is crucial. Wet hash will mold.
Air Drying Method (Most Common):
Spread wet hash thinly on parchment paper or cardboard
Break into small pieces with a spoon or card
Place in a cool, dark area with good airflow
Turn/break up the hash daily
Dry for 7-14 days until completely dry
Freeze Dryer Method (Professional):
Spread hash on freeze dryer trays
Run full cycle (24-48 hours)
Results in superior colour and terpene preservation
Understanding Hash Grades by Micron
Micron Size
Quality
Description
73-120µ
⭐⭐⭐⭐⭐ Premium
Full melt, pure trichome heads
45-73µ
⭐⭐⭐⭐ High
Near full melt, excellent quality
25-45µ
⭐⭐⭐ Good
Half melt, good for pressing
120-160µ
⭐⭐ Medium
More plant material, cooking grade
160-220µ
⭐ Low
Mostly contaminant, discard or edibles
The 73-120 micron range is often called the “golden zone” — this is where you’ll find the purest, most potent bubble hash.
Tips for Better Quality Hash
1. Keep Everything Cold
Temperature is the most important variable. Work in a cold room if possible, and don’t let the water get above 40°F.
2. Be Gentle on First Wash
Aggressive agitation breaks up plant material, contaminating your hash. Save the vigorous mixing for later washes.
3. Start with Quality Material
You can’t make great hash from bad cannabis. Use the best flower you can — strains like Durban Poison or Do Si Dos produce excellent hash.
4. Freeze Your Material
Minimum 24 hours in the freezer. Longer is better — some producers freeze for a week or more.
5. Use Quality Water
Filtered or reverse osmosis water produces cleaner hash. Tap water minerals can affect quality.
What to Do With Your Bubble Hash
Smoke It
Top a bowl of flower with a piece of hash, or smoke it pure using a pipe with screens.
Press It Into Rosin
Bubble hash can be pressed with heat and pressure to create “hash rosin” — considered by many to be the pinnacle of cannabis concentrates.
Make Edibles
Lower-quality hash (larger micron) is perfect for cooking. It’s already decarbed slightly from the drying process.
Dab It
Full melt hash (73-120µ) can be dabbed like other concentrates. It won’t leave residue on your banger.

Making bubble hash at home is a rewarding process that connects you to one of the oldest forms of cannabis extraction. With just ice, water, and some patience, you can create a clean, potent, full-spectrum concentrate that rivals what you’d find in any dispensary.
Start with quality material, keep everything cold, and take your time with the drying process. Your reward will be some of the purest, most flavourful hash you’ve ever tried.
The most traditional infusion method. Kief (the trichome crystals collected from cannabis flowers) is either mixed into the flower or coated on the outside of the joint.
Pros
Cons
Natural, full-spectrum experience
Moderate potency increase
Burns evenly
Can be messy on outside
Preserves terpene profile
Less potent than other infusions
Hash-Infused Pre-Rolls
Hash is compressed kief that’s been processed into a solid form. Hash-infused pre-rolls feature hash crumbled and mixed into the flower, providing a smooth, potent smoke with classic flavour.
THC distillate is a highly refined cannabis oil that’s nearly pure THC (90-99%). Pre-rolls infused with distillate are extremely potent but may lack the complex flavour profile of full-spectrum products.
Pros
Cons
Maximum THC potency
May lack entourage effect
Consistent effects
Can taste harsh
No plant taste interference
One-dimensional high
Live Resin-Infused Pre-Rolls
Live resin is made from flash-frozen cannabis, preserving the plant’s full terpene profile. Live resin-infused products offer the best of both worlds: high potency AND exceptional flavour.
This is considered the premium option for cannabis connoisseurs who want potency without sacrificing taste.
Rosin-Infused Pre-Rolls
Rosin is a solventless concentrate made using heat and pressure. Rosin-infused pre-rolls are popular among those who prefer concentrates made without chemical solvents.
Some pre-rolls are infused with added terpenes to enhance flavour and effects without necessarily increasing THC. Products like King Palm Terpene Infused Rolls offer unique flavour experiences.
How Are Infused Pre-Rolls Made?
There are several methods producers use to create infused pre-rolls:
1. Interior Infusion
Concentrate is mixed directly with ground flower before rolling. This creates even distribution and consistent burning.
2. Core Infusion (Snake Method)
A “snake” of concentrate runs through the center of the joint. As you smoke, the concentrate melts and vaporizes along with the flower.
3. Exterior Coating
The outside of the joint is coated with oil and then rolled in kief. These are visually impressive but can burn unevenly.
4. Combination Method
Premium infused pre-rolls often use multiple methods — concentrate mixed in, a core, AND an exterior coating. These “caviar” or “moon rock” pre-rolls are the most potent.

Who Should Try Infused Pre-Rolls?
Infused pre-rolls are ideal for:
Experienced users with higher tolerance
Medical patients needing stronger relief
Special occasions and celebrations
Those who want efficiency (more effect per puff)
Concentrate enthusiasts who also enjoy flower
You might want to skip infused pre-rolls if:
You’re new to cannabis
You have low THC tolerance
You need to stay functional
You’re on a tight budget
Tips for Smoking Infused Pre-Rolls
1. Start Slow
Take 1-2 puffs and wait 10-15 minutes before continuing. The effects are significantly stronger than regular joints.
2. Use a Proper Holder
Infused pre-rolls can get sticky and hot. A pre-roll case or holder keeps your fingers clean and cool.
3. Don’t Rush
Smoke slowly to let the concentrate vaporize properly. Fast puffing wastes product and creates harsh smoke.
4. Store Properly
Keep infused pre-rolls in airtight containers. The added concentrates can dry out or become degraded when exposed to air.
5. Share the Experience
One infused pre-roll can easily serve 2-4 people. They’re perfect for sharing at parties or sessions.
Infused pre-rolls represent the next evolution in pre-roll technology. By combining premium flower with potent concentrates, they deliver an experience that’s significantly stronger and longer-lasting than traditional joints.
Whether you opt for kief-dusted, hash-filled, or live resin-infused, remember that these products pack a serious punch. Start low, go slow, and enjoy the ride.
Pro tip: A proper grinder will give you an even, consistent grind that burns better in a gravity bong. Finely ground flower creates optimal airflow.
For the Waterfall Method
Same materials as above, but you only need one bottle (no bucket required). You’ll poke a hole near the bottom of the bottle instead.
Method 1: Classic Bucket Gravity Bong
This is the most popular method and delivers the biggest hits.
Step 1: Prepare the Smaller Bottle
Take your smaller plastic bottle (a 500ml water bottle works great)
Cut off the bottom 2-3 inches using scissors or a knife
Remove the cap and set it aside
Step 2: Create the Bowl
You have two options:
Option A: Aluminum Foil Bowl
Poke a hole in the bottle cap (slightly smaller than your fingertip)
Mold aluminum foil over the cap opening, creating a bowl shape
Use a toothpick to poke 5-7 small holes in the foil for airflow
Option B: Socket Bowl (Recommended)
Find a socket wrench piece that fits snugly in the bottle cap opening
Push it through the hole — it should fit tightly
This creates a more durable, reusable bowl
Step 3: Prepare the Water Reservoir
Fill your bucket or larger container with water
Leave about 2 inches of space at the top
If using a 2L bottle as your reservoir, cut off the top portion
Step 4: Assemble and Use
Submerge the smaller bottle in the water (cap off), leaving just the neck above water
Pack your bowl with ground flower — don’t overpack
Screw the cap/bowl onto the bottle
Light the bowl while SLOWLY lifting the bottle upward
Watch the bottle fill with thick, milky smoke
Stop lifting before the bottle comes completely out of the water
Remove the cap, put your mouth over the opening
Push the bottle down into the water as you inhale
Important: The water pressure forces the smoke into your lungs — you don’t need to inhale hard. Let gravity do the work.
Method 2: Waterfall Gravity Bong
The waterfall method is easier to make and great for solo sessions.
Instructions
Take a plastic bottle (1-2L works best)
Create a bowl in the cap using the same method as above
Poke or cut a small hole near the bottom of the bottle (about the size of a pencil)
Cover the hole with your finger
Fill the bottle with water while covering the hole
Screw on the cap/bowl
Pack the bowl with ground flower
Light the bowl and release your finger from the hole
As water drains out, smoke fills the bottle
Once drained, unscrew the cap and inhale
The waterfall method is more portable and only requires one bottle, making it perfect for outdoor sessions.
Tips for the Best Gravity Bong Hits
1. Grind Your Flower Properly
A medium-fine grind is ideal. Too fine and it might pull through; too coarse and it won’t burn evenly. A quality 4-piece grinder gives you the perfect consistency every time.
2. Don’t Overpack the Bowl
Less is more with gravity bongs. Start with a small amount — you can always do another round. A quarter of what you’d put in a regular bowl is plenty.
3. Lift Slowly and Steadily
Rushing creates thin, weak smoke. Slow, steady lifting produces thick, milky hits. Aim for about 3-5 seconds to fill the chamber.
4. Use Fresh, Cold Water
Cold water makes the smoke slightly smoother. Change the water between sessions to keep things clean.
5. Corner Your Bowl
Light only a portion of the bowl to get multiple hits from one pack.
Best Strains for Gravity Bongs
Since gravity bongs deliver such potent hits, strain selection matters. Here are some favourites:
Making a gravity bong is a classic cannabis tradition. Whether you’re looking for a more efficient way to consume flower or just want to try something different, the gravity bong delivers an experience unlike any other method.
Remember: start slow, use quality flower, and enjoy responsibly. The gravity bong is called a “gravity bong” for a reason — it’ll put you on your back if you’re not careful!
