WHAT YOU NEED
- Three large buckets capable of fully submerging your buds in water. Standard 10l plastic buckets should be sufficient.
- Baking soda (sodium bicarbonate)
- Lemon juice
- Lukewarm water
- Large spoon (for stirring)
Fill one of the three buckets with lukewarm water. Around 20°C is good. For every litre, add 2 teaspoons of baking soda and 2 teaspoons of lemon juice. So, if you’re using a 10l bucket, add in 20 teaspoons of baking soda and the same amount of lemon juice. Using the spoon, stir for a bit to let everything dissolve.
The baking soda and lemon juice will produce a mild chemical reaction that breaks up stuff like dirt and other contaminants. Yet, it isn’t strong enough to dislodge trichomes.
Fill this bucket with some lukewarm water. Again, about 20°C will be fine. We will use this bucket to rinse off the water from bucket 1.
Fill bucket 3 with cold water only. This is our second rinsing bucket.
And that’s it! We now have a “washing bucket” (bucket 1) and two buckets for rinsing. We’re using two rinsing steps because we want to ensure all debris is cleaned off.
