Cannabis concentrates can be made with different techniques. Concentrates contain the full spectrum of cannabinoids and terpenes. This is because unlike extracts, when making concentrates you’re removing the whole trichome head instead of dissolving it in a chemical solvent, where you can lose some compounds.

1. Dry Sift Hash

Dry sift hash is also known as kief. This is the traditional method of collecting trichomes, it consists of separating the trichomes from the plant material by sifting.

Dry sift hash is also known as kief.

This method has been used for a long time all over the world, especially in places where hash is consumed a lot like Morocco, Lebanon, and Afghanistan.

2. Bubble Hash

Bubble hash (or water hash) is another way of making hash, it uses water as a way to separate the trichomes from the plant material and the result is fairly similar to dry sifting, although it can reduce the amount of impurity, resulting in a higher quality hash.

3. Bubble Hash vs Dry Sift Hash

Dry sift and bubble hash produce kief, the main difference being the process they go through. While dry sift is made by rolling the buds or trims in a fine mesh, bubble hash uses extremely cold water to separate the trichomes from the plant material.

Both of these techniques have advantages and disadvantages, although water hash is considered to have better quality, the end result solely depends on the quality of the flowers going in and your experience.

Kief can be turned into hash by applying heat and pressure with your hands.

You can achieve a very good quality hash either way if you know what you’re doing, although each way of doing it has its pros and cons.

Either way, the only way to guarantee a good quality is growing buds full of trichomes.

Dry Sift Hash Cost

There’s a big difference between them when it comes to cost. Dry sifting only requires a sift screen and a flat surface while for bubble hash you will need bubble bags, ice, cold water, and a water hash machine.

Materials needed for dry sifting cannabis plant material.

Note: Instead of the extraction machine you can use several buckets and a long spoon to stir but it is not ideal if you want to produce the best quality possible.

Obviously the cost will depend on where you live, but you can find the material required for dry sifting starting at $15 up to $60.

Bubble Hash Cost

For water hash, the machine by itself can cost up to $250 and it doesn’t even come with the bubble bags.

Not only is it expensive but also requires experience, making it better suited for more experienced growers.


When talking about quality, most growers agree water hash is better.

Have in mind that the quality solely depends on the quality of the flower going in, but because water hash uses water to separate the trichomes, the end result can have way fewer impurities.

Dry sift hash can also have great quality, but because the trichomes fall directly to the surface where you collect it, it can contain a lot of impurities.

If you’re making hash for your own consumption at home, this won’t be a huge deal, but commercial growers who need to produce the best hash they can always opt for bubble hash because it is better for producing 5 or 6-star full melt hash.


Neither of these techniques is actually super hard, although you will need a minimum amount of knowledge for both of them.

When dry sifting buds, you need to know the amount of pressure so you don’t disintegrate the buds, and with bubble hash you need to know for how long you can run the machine and at what strength.

You can easily look up this information on the internet, so it's just a matter of preference when talking about the level of difficulty. Although you can make a mess when making bubble hash because it uses water but that shouldn’t be a problem. 


Yield depends on the number of trichomes your plant material has and this also depends on the quality you aim for.

When dry sifting there’s usually only one screen, this means all the trichomes fall in the same place, so they’re mixed and there’s no way to separate them. So you can actually get more hash but you cannot separate it by quality.

With bubble hash you may (sometimes) get lower yields because the water (with the trichomes mixed in) goes through several bubble bags and sometimes it can be hard to collect everything, also it is really easy to spill water. 

Although the several bubble bags can be an advantage if you want to separate your hash by quality because the micron size of the filter separates the trichomes by size (and consequently, quality).

4. In Conclusion

Although water hash can be a little bit more expensive, both methods are fairly simple. The decision is obviously up to you and will depend on the amount of plant material you want to process and how much you’re willing to spend.

I got 134g off this gal growing in 3 gal pot with 24 hours of light. i'm stoked with the result! Smells like diesel. Was a great grow overall.

Not only it has a delicious terpene profile but it also produces a huge amount of resin.

Remember that although the way you make your hash can affect the quality of the product, it mostly depends on the quality of the flower that goes in.
