On the Weed the Trichomes look like little Mushrooms,i had 4 Weeds which i could compare and there was clearly a difference,i had a White Whidow which was not White at all it looked more Brownish.Under Microscope i could see that all Trichomes turned into a Amber colour and that there was soo many of them that the whole Weed looked brownish,they also all was bend over.
Other Weeds had straight Trichomes.Also intresting was that with the Microscope you cannot only see how many Trichomes the Weed has,you also can see how big the "Resindrop" on their Top is.
I think when the Trichome bends over cause the resindrops weight is a good sign
I also watched Tobacoo under it,and it was a bit scary to see that it was coated in some white cristall stuff,i guess thats some extra shit they put into the tobacoo
