This reduces the volume and allows more leaf to be stirred at once.

Add a second later of ice, more weed then top off with Ice lots of rough shaped ice. Top off with water leaving about 1” from top of bucket.
Place in the fridge for about 30 minutes.

After the mix sits and is really cold remove place in sink and start stirring in a motion so that the stuff on bottom comes to top and the ice and water agitates to the bottom. The roundy roundy will come later but at first concentrate on moving the mix in a up to down motion as the trichomes break off and pass the screen they will naturally fall into the bottom of the bucket. As the ice breaks apart and you get more room you can increase the stirring action and really whip it up. This takes 6-8 minutes and it took a few batches before I could do it the entire time without a small break but you get used to it.
