The Calculator
Fill in what you know. The calculator uses real-world yield data from hundreds of home wash reports to estimate your return.
Your Results
When It's Almost Always Worth It
Fresh frozen sugar trim from known washer genetics. This is the sweet spot. You're turning waste material into something genuinely valuable. Even 50g of fresh frozen trim from a strain like GMO or Papaya can yield 2-4g of quality hash.
You already own the equipment. Once you've bought bags and a bucket, your per-wash cost is basically just ice. At $5-10 in ice per session, the math almost always works out.
You grow your own. Your material cost is effectively zero. The question isn't "is it worth it?" — it's "why aren't you doing this with every harvest?"
When It's Probably Not Worth It
Less than 30g of dried trim. You'll spend 2-3 hours washing, drying, and cleaning bags for maybe 1g of hash. Your time has value. Wait until you've accumulated more material — freeze it as you go.
Fan leaves with no visible trichomes. You can wash fan leaves, but the yield is dismal (under 1%) and the quality is almost always 1-2 star. Only worth it if you're making edibles and have nothing better to do.
Old, dried-out trim that's been sitting in a paper bag for 6+ months. Trichome heads degrade and oxidize over time. You'll get dark, low-quality hash. If you have old trim, edible infusion is a better use.
The Time Factor
This calculator doesn't account for your time, and that matters. A typical 4-wash session takes 3-4 hours from setup to cleanup. Drying without a freeze dryer adds 3-14 days of occasional attention.
If you enjoy the process — and most people do after the first run — time isn't a real cost. If you're doing it purely for economics, factor in your hourly rate.
At minimum wage ($17.40/hr in BC, $16.55 in Ontario), that 4-hour session costs you $66-70 in time. For most home growers, the first wash is always worth it because you learn the skill. After that, you'll know if it's your thing.
Comparison: Making vs. Buying
OCS (Ontario Cannabis Store) bubble hash: $25-37/g for mediocre quality. CannaFarms BC Bubble Hash at $37/g gets routinely trashed in reviews — people report dark colour, harsh smoke, and "barely 2-star" quality.
Your homemade hash from decent genetics: Typically 3-4 star. Costs $2-8/g when you account for equipment amortized over multiple runs and ice. Fresher, more flavourful, and you know exactly what's in it.
The legal market's hash offerings are, bluntly, overpriced and underwhelming. Making your own is both cheaper and better — once you have the technique down. Our beginner's guide walks you through the full process.
