How to water cure weed?

Water curing is the process of submerging your harvested weed into water within five to seven days to remove its dirt and impurities. There is no professional skill needed to water cure your harvested buds. All you need is freshwater, a container, and harvested Cannabis buds. To do this curing process, you need to trim the buds and remove the stem and fan leaves. Then, submerge your buds in the water. During the procedure, regulate the water temperature between 65 degrees to 75 degrees Fahrenheit (18°-24° Celsius) only. Also, you have to change the water at least once a day to make sure that buds are soaked in freshwater during the entire process. When water becomes clearer, it means that a few dirt and impurities are left in your weed. Then, hang your buds to dry if you are sure that dirt and impurities have been removed.

What is a water-cured weed?

Harvesting is one of the best parts of being a cannabis grower after a series of weeks of taking care of your crops. However, it is not safe to try and use it immediately. If you are excited to try your harvested Cannabis, water curing is one of the best alternatives, especially if you do not want to wait that long.

Water-cured weed undergoes osmosis that washes out chemicals, chlorophyll, pesticides, pests, or anything else you do not want to smoke when you consume your weed. It removes unwanted substances and purifies your Cannabis. The water curing process involves submerging your buds in water and is a faster method than traditional curing.

How does water curing work?

Like any other traditional curing, water curing works the same in many ways. Though you have to sink the buds in water for around a week only, unlike air curing, you need to wait longer to break down the residual substances. 

Water-soluble substances in your weed like insecticides, salts, sugars, chlorophyll, and other unwanted substances diffuse in the water once buds are submerged in it. Water curing is a fast method than waiting for your buds to digest sugars and salts.

Cannabinoids in weed are fat-soluble, making water alone not enough to remove them from your Cannabis plant. Thus, you can safely use water to remove harmful chemicals from your buds without negatively affecting your harvest.

On the other hand, water curing may not be best for someone pleased by their aroma and flavors. It is because terpenes that produce their smell and taste are water-soluble that could get easily washed out.

How does water curing differs from bud washing?

Water curing and bud wishing are different from each other. The goal of bud washing is to clean the buds after the harvest. It only takes place over a matter of minutes, unlike water curing, which submerged buds for 5 to 7 days. In bud washing, growers dipped their harvest into a series of buckets of water to clean the buds and improve their taste. After giving the buds a quick dip in the water, they move them to the drying rack.
