Don't "get rid of" the light seeds! Yes, they are likely immature (but I've seen pale gray seeds that were mature), but it is a sin just to toss them! Plant them in a field or park somewhere. Fight global warming- PLANT ALL YOUR SEEDS! If they grow- HURRAH and maybe you get some free bud (or some kid does). In a land fill, the chances of them growing is practically nil. Give them a chance to grow.
