I tried using an electric device to stir my trim. Made a mess out of it and took for ever to rinse the green out.
My method is to use multiple buckets with the bottoms cut off. The bottom bucket has 1.5" holes around the base so it will not hold water. I put the 25 bag in the bottom bucket then drop a bucket with no bottom in. Place the next bag in that bucket and insert the next bucket with no bottom. continue till all of the bags accept the 220 are stacked up. I place the 220 in a bucket that holds water.
Ice, trim, ice, water..
Let it set for 15 minutes then "gently" stir with a wooden spoon for 30 minutes. Pull the 220 bag and set it in a large glass bowl. Dump the water into the stacked buckets while they are sitting in the kitchen sink. Use the sink sprayer to rinse the bags completely of any impurities.
The stacked buckets hold the screens completely flat and about 4-5 inches apart. No need to pull each bag and wrap it around a bowl for scooping, just reach into the bucket and scoop it up. Use the sprayer to re- center what is still in there and scoop again!!
All of the bags produce beautiful blonde trichomes accept for the 25 which no matter how much you rinse it, will be green.
I will purchase a mini washing machine soon enough which will take the place of the first bucket, 220 bag and wooden spoon. My current method eats up 4 hours per month since I run my trim 4-5 times.
