I’ve had the RosinBomb Rocket for about a year now, and I’ve used it quite often. It’s a portable electric rosin press. It’s light – weighs less than 20 pounds – you can carry it around to different places. It’s rated for between 1 and 5 grams. You will find that the sweet spot is 2.5 grams to get maximum yield. 

This article will illustrate five different presses ranging from 1 to 5 minutes. In the end, you will see the difference that time of press makes to rosin yield. This short demonstration will be pressing Walter White. You may also want to use a prepress. A prepress is a device that you can use to squeeze your marijuana into shape so that it’s easier to place it on the Rosin press.

What you will need

  • RosinBomb press
  • Pre-press
  • Marijuana
  • Weigh scale
  • Parchment paper
  • Scraper

Prepress five snugs of White Walter Marijuana each 2.5 grams and set them aside. Normally, you want to prepress before placing it into your prepress because some strains of marijuana expand after an initial press. 

Pressing on the RosinBomb

When using the RosinBomb press, take your marijuana and place it between sheets of parchment paper. It’s very important that you use parchment paper and not wax paper. Wax paper will melt and ruin your marijuana. I like to repress my snugs so that they are properly compressed. 

Place your first snug into the middle of a parchment paper and place it onto the lower jaw of a RosinBomb press. Make sure that all four sides of your parchment paper are extending over the sides of the pressing plate. Turn on ResinBomb press and hold the press function button until your snug is fully compressed. Leave the ResinBomb in the compressed mode for one minute. 

Repeat this step for durations 2 minutes, 3 minutes, 4 minutes and 5 minutes respectively. From first glance, I could see that there was a difference in the quantity of resin yielded from each duration of the press. The four-minute press yielded the most amount of resin. 

Scraping Rosin

When scraping rosin, think about using a block of marble that you have chilled in the freezer and use it as a cold base. It makes it a lot easier to scrape up resin when it has been chilled. 

Results

You might not get much from the 1-minute press. This DIY resulted in 0.01g, and the scale could barely register this yield. The two and three-minute press yielded 0.1 grams of resin, slightly under 5 per cent yield. My four-minute run managed 0.14 grams, the best result yet. The last run, 5 minutes, yielded 0.1 grams as well. Alternatively, you can also extract rosin using a hair straightener

Conclusion

As more time is applied, each one is going to be less quality as time goes on. The four-minute run yielded a little extra, about 40 per cent or so. Overall, I got about 4.4 grams of resin from 12.5 grams of marijuana. I bought my weed at about $3 a gram, so I say it’s a good rate and it’s a lot cheaper than buying the resin yourself because you know exactly what you are getting.
