Wanting to use dry ice

I am sure dry ice helps but the question is does it really make that much difference and is it worth the time and money.

Yes and yes. It works wonderful. Some people complain there can be a little plant matter because the vigorous shaking(especially if your using dry material). I wet trim and freeze everything until I have enough. Then I use that and it comes out super nice and clean.

So use dry ice right in the mini washer with the bubble bags?

So what I do is load a 5 gal bucket with layers of trim and dry ice. Let it sit for like 5 min to really freeze. Put my bubble bag over the bucket and make it tight over the opening(mine are made for 5 gal) turn it over and shake while holding the bag to keep screen tight. I do this for like 30 seconds. Let it sit for another 5 min and shake again for a minute or two. I usually shake over a few pieces of parchment paper so it doesn’t stick and it keeps the table clean. It helps it you leave it a bit on the parchment paper to warm up and let the condensation from the cold come off it a little. Gather it up with a cleaned razor blade (they come packed with a coating of oil so clean carefully with soap) and keep in a bowl to dry more. Turn it over a bit after a day to make sure the moisture is gone. Do until it looks dry. I personally then squeeze into 1gm pucks using a pollen press but you can do so much with it.
