Seeds Float.

Seeds of the coca plant, used for producing cocaine among other thing, are checked for quality by placing in water. If they float, they're typically bad.

I realize we're talking about different plants, and the seeds of marijuana weigh less, but is this true with marijuana as well?

Personally, I don't pay attention, I just soak in water overnight before going damp paper towel waiting for them to crack to plant. I was just curious.

People put pot seeds in water so they can soak up enough water to germinate (more quicky??). Anyways, I know they float at first but once they soak enough water they sink. Hope this helps at all..

if mj seeds float they usually have a better chance of germinating...but if they dont float they CAN still work, i think the its just less likely...i got a few that sunk right off the bat to germinate after multiple soakings and in between the sheets...good luck...

^hey run them on 24-48 hours in the shot glass, they should sink btw...and 24-72 hours with the towels, repeat if neccesary...i had really really old seeds, like 2 years, and i got them to germinate with this method...it took two soakings to get the last ones to sprout!
