They aren't evergreens. How big (tall) is that thing.Most people bloom after 4-6 weeks. When it starts blooming it will stretch to at least twice the size it is. A 75 watt light won't penetrate much more than a foot.So what should I do. Should I switch it to flowering 12/12 or what do u think. This is the first time I've heard that there falling off cuz there old so idk. N isn't that enough light though
