1. The first step is to place the hash bags inside the bucket, the first to go in is the 25 micron bag (colour purple). Make sure you line the inside of the bucket properly with the Hash bag, and smooth out the mesh screen at the bottom of the bucket.

Keep on with the rest of the Hash bags in numerical order of their size. The next Hash Bag to go in is the 120 micron (yellow) one, and then after that place the 75 micron (blue) Hash Bag in the bucket.

Place the 220 micron work bag (orange) in the bucket last of all, so that all the Hash bags are now inside the bucket, nested inside each other...

2. Now you need to pour cold water into the Hash Bags in the bucket, until it's about half full. You don't have to use a flower vase like in our picture, any way you get the water in the Hash Bags is fine!

You want the plant material to float above the screens of the Hash Bags, so ensure that the water is high enough to cover the screen on the bottom of the upper HashBag. We put a little marker in our bag to show you!

3. Then take your plant material and pour it into the bucket containing the Hash Bags. Dried plant material will usually give you the best results. Regarding quantity, you can use up to 400g of dried plant material or leaves in our Hash Bags.

4.Now it's time to put ice in the bucket, filling it almost all the way up. You should have enough pieces of ice in the water so that it never all melts, this way the ice keeps the temperature of the mixture lower, and is a very important part of the process.

5. Then use something to stir the mixture in the bucket, for at least 15 but up to 20-25 minutes. The way to tell when you have mixed everything up long enough is that a foamy or frothy head will form on the top of the mixture. You can use an implement on the end of an electric drill as in this picture . . .

Or even an electric hand mixer from your kitchen! As mentioned above it's vital to keep actual pieces of ice in the mixture at all times, because the ice ensures that the water stays cool enough to cause the resinous glands (trichomes) to separate from the plant material, and then collect on the Hash Bag screens.

6.After you have mixed the ice and plant material enough to get a frothy head, then let the mixture settle for 20 minutes to half an hour. Once the mixture has had enough time to settle, take the bags out of the bucket one by one. This is done in reverse order to putting them in, so the first to be pulled is the 220 micron screen Hash bag.

When you pull out the hash bags, you let the water drain through the filtration screen at the bottom of the bag, back into the rest of the bags that are lining the bucket. The 220 micron Hash bag contains the plant matter, you can run this through your Hash bags a second time to make sure you collect all the resins.

The next Hash bag to be pulled is the 120 micron bag, followed by the 75 micron screen bag. These bags will have resinous extracts or bubble hash, in different degrees of purity.

The last Hash bag to remove is the 25 micron screen bag. As you get to the smaller screens, the water is harder to drain from the bags - to help this process, when you lift each bag out of the bucket twist the top shut, and at the same time pull down towards the bottom of the bag.

7.Once you have drained each Hash Bag of water, then turn the bag inside out and place it over a bowl in order to collect the deposits from the mesh screen at the bottom of the bag. There are many tools you can use for this, it's important that it should have a clean edge, such as a metal spoon or credit card, etc. There are 3 grades of extracts to collect. Of these the "purest" grades will come be in the 75 and 25 micron screen Hash Bags, but usually the resin extracted from the 120 micron bag can also be used!

8.After you have collected the herbal extract or resins from the screens in the Hash Bags, you have to remove any excess moisture from it. Take a tea towel and put some absorbent paper or a piece of blotter on it. Scoop the 3 extracts onto one half of the paper or blotter, and make sure to keep the three grades separate. Then fold the blotter in half, and fold the tea towel over the blotter, and press lightly down on the towel with a bottle or rolling pin. This will squeeze any remaining water out of your extracts, which will be absorbed by the towel. From this process you will get patties of herbal extract which can be used immediately if you want! If you decide you want to store your extracts for a long period of time, then cut or chop up each patty on a clean piece of cardboard, and put this in your freezer for half a day or a day. Any remaining moisture is drawn out by the cardboard, which takes away any danger of mold forming while you store your extracts.
