i highly recommend silicate as a moisture absorber more effective than rice i use them for both seeds and pollen there the little packets found with vitamins and the like.
Around here hemp polination can be a real problem.. There are alot of industrial hemp crops within a few miles of here,, I've watched a few lines go downhill, only wishing they'd herm'd more definately, but alas hemp pollen is worse..
wow there is not a spore of hemp pollen in cali that i have ever heard of. my friend from new orleans says hemp called ditch weed grows wild along highways very commonly. i know in spain that pollen from herb grown in morrroco can travel many miles to pollinate outdoor grows. im glad i dont deal with that where i am.
I know that Wisconsin is planted pretty thickly with ditch weed.. Might suck hard I'm sure, but I'd love to be able to plant wherever I damned well pleased and not have anybody take notice of it..
slowly but surely people including law enforcement are letting cannabis take a back seat to real societal problems its a long time coming but still much progress to be made.
