I also wanted to point out I will be growing auto-seeds so I don't need to change light cycles. I'm using a 18/6 light cycle all the way through. I read that these plants are great for beginners to get a feel for how the plant grows. After a few rounds I am gonna try regular strains. I got the tent that size because I planned on getting a 600 watt system down the road and led panels. The fan/filter combo I got isn't even close to that. So I think I'm gonna need a bigger one.
