Cannabis enthusiast and student of the art of solventless extraction.
Preparing all the equipment and going through the labor-intensive process of ice water extraction takes a good amount of time and energy, so most bubble hash extractors won’t wash anything under a quarter pound (4 ounces) per run. Anything less may only yield a few grams of high quality hash, which may not be worth the effort to some growers.
However, don’t let this stop you if you want to make bubble hash at home and you’re not sitting on pounds of material. You can wash some premium bubble hash starting with just 1-3 ounces of high quality cannabis material.
As always, the key is to start with exceptional cannabis. Aim to use cannabis flower or trim leaf that’s been dried and lightly cured, as older material may not produce as effectively. Or, you can use fresh frozen material as well, and skip the drying and curing process altogether.
When deciding how much material to use for making ice water hash, we have to consider the volume of our bubble bags. The most common sizes of bubble bags are 1 gallon, 5 gallon, and 20 gallon. For the extraction, we need to fill the bags without over stuffing them.
Take into account the space needed for water and ice, in addition to the cannabis material. There should be enough space in the bag to generate turbulent water currents while mixing/stirring.
Here’s a reference guide for how much cannabis material you can use for each size bubble bag set.
- 1 gallon wash bags: 1-2 ounces or 28-56 grams
- 5 gallon wash bags: 3-8 ounces or 80-225 grams
- 10 gallon wash bags: 6-16 ounces or 160-450 grams
- 20 gallon wash bags: 1-2 pounds or 450-900 grams
- 32 gallon wash bags: 2-3 pounds or 900-1350 grams
- 44 gallon: 3-4 pounds or 1350-1800 grams
Fresh Frozen Cannabis:
- 1 gallon wash bags: 5-10 ounces or 140-280 grams
- 5 gallon wash bags: 15 to 36 ounces or 420-1008 grams
- 10 gallon wash bags: 40 to 80 ounces or 1120-2240 grams
- 20 gallon wash bags: 5-10 lbs or 2200-4500 grams
- 32 gallon wash bags: 10-15lbs or 4500-6800 grams
- 44 gallon: 15-20lbs or 6750-9000 grams
With 1 ounce of high quality dried and cured cannabis flowers in a 1 gallon bubble bag set, you can expect somewhere between 3-5 grams of hash.
For Dried, Air-Cured Cannabis, 15-20% yield is a good target. For fresh frozen, look for 3-8%. The rule of thumb for calculating wet (fresh frozen) weight to dry (air cured) weight is 5:1. So if you get 4% wet, that’s equivalent to 20% dry.

It's better to err on the side of using less material for the size of your bags than overcrowding the material in bags that are too small. If you've got a lot of material to put through 1 or 5-gallon bags, you can always split up the material and run multiple washes.
Success depends not only on the starting material, but on your technique and the equipment you’re using. See our Guide To Washing Bubble Hash for an outline of the entire process.
FREQUENTLY ASKED QUESTIONS
How many grams in one pound?
There are about 453 grams in one pound.
What is the least amount of cannabis you can wash for bubble hash?
You can wash as little as one ounce of cannabis material, but most people will wait until they have several ounces of material.
What happens if you try to wash too much material in your bubble bags?
If you crowd the bubble bags with too much material, it will be difficult to effectively remove all resin glands from the cannabis. It's better to leave extra space in your wash bags than not enough space.
Should you use trim or whole cannabis flowers for washing hash?
Either type of material is fine, as long as it's covered in trichomes!
What size bubble bags should I buy?
For most home extractors, a 5-gallon bubble hash wash bag set is sufficient. The larger sizes are great for commercial operations.
