Hey every body ! So im new to this an i have 2 starter's (foot an a half tall) a freind tried to kill them cause they are kinda runty and they wouldnt die so i took em an now they got mold and the tips of the leaf's are bent and crunchy. Using these one's to get the hang of it before i start my room so here we go . On the mold i know you can use spray's or sulfer burner's , so which is more affective an why ?
