Hi all , now I have my seeds on there way but I would like to know how many plants you can grow per square mtr , the seeds are the hash plant from Herbies , I am thinking 6 in that space , I have another square mtr but that is my sons space , pot size is 20 ltr ? [ 12 in by 12 in by 12 in ] pot dimensions, soil --- now next question , can you grow them at the same time as photo plants or would the change in light cycle stuff them up , like going from 18/4 to 12/12 ? :tiphat: Thanks guys .
