I have limited space because i grow many other plants indoors under artificial lights. I mainly grow plants stacked in height, i get seed from all over the world ( cacti, eucalyptus species, tropicals etc) I have grown CBD strains outdoors many times but when winter comes i want to do it indoors. I am wondering about growing in a small space , i have have seen a tent of 2 feet in length, 3 feet wide and 3 feet high. i am planning to buy two of those. 1. what is the average height ( optimal ) in a 3 feet high space to induce flowering ( they probably stretch when flowering i guess). 2. how many plants can i put into one tent ?
