i have chem91 skva bx4 from elite kings genetics and my green crack clone only at 17 days 12/12 today,i have 5 chem females and 4 males that i culled today,but i pollinated all plants lower branches with one of the chem males the other day...the male i used has great structure and has an incredibly offensive pure chem/fuel smell....so ill have tons of seeds to play with.the gc is completely done at 52 days and is a wicked potent,tasty clone with a great yield,it took 4 years of begging to get it.i think the chem will just improve on the smoke,which is already killer sativa smoke with a fruity,lemon,skunk smell.....ill update as flowering progresses....im pretty pumped to try the new cross in the future
