How to Clean Cannabis Seeds – Processing Bulk Cannabis Seeds

How a Cannabis Seed Cleaning Machine Works for Hemp and Cannabis
You have cannabis seeds…and you are wondering how do I clean these cannabis seeds easily? How do I process cannabis seeds in bulk?
Cleaning cannabis seeds in bulk can be a chore! I have found the easiest way for me was blowing on them in a shallow bowl…but this meant you did alot of blowing!
I knew there had to be an easier way…which lead me to Youtube. There I saw someone telling how to build a seed cleaning machine that used a vacuum to separate the heavier seed from the chaff. It was not difficult to build, and it works perfectly.
One can adjust things so it will even separate the immature seeds form the mature…but I have never bothered to try to dial it in that closely. I just let is give me just the seeds, then I separate the best from the rest by hand. I pride myself in only selling fully mature seeds that are for sure viable. And here is a horror story about seed quality….I was wanting to produce seeds of the strain Freakshow. I spent $10 per seed, and bought 10 so I could make seed. I will not name the seed bank, but when I got the seeds they were ALL white, and hollow, you could easily crush them with your fingers…not one viable seed out of the $100 worth! I got back to the company and he assured me they would end replacements…they of course never came.
That brings me to this….my promise to you my customer…I will never sell you seeds like that, I guarantee germination, and I pretty much guarantee satisfaction. If you have a problem with my seeds…for any reason, get back to me I can help! I love making customers happy, and I want to turn every customer into a repeat customer.
Do you know of a different way to clean cannabis seeds in bulk? Please leave a comment and tell how you do it. I would love to hear your take on it!
