Strain question

What strains produce the greatest amount of trichromes? Are there any strains breed for that purpose, the outside trichs?
Thanks, I'm looking myself, I'm thinking White Widow would proclaim to have the highest count. Am I wrong?

they came out with a strain called elephant bud suppose to have at least 34% thc an w.w. has what bout 20 thru 25 % but then again it all depends on how you grow it is what i have also heard i havent tried either well smoked the white widow but just heard bout the elephant bud never grew any great single strain just bag seeds and some of them came out to be bad ass crystals every were including some of the big fan leafs but idk good question
