I have heart problems and my last grow really took it out on me, I was looking after 11 sativa plants in a 4x4 space and they were all massive, I had to take them out everyday just to feed them until run off, it took me over an hour every day just to feed them. It's not that I'm lazy, I just want to make things more simple and less time consuming, in my new grow I only have 6 plants this time so it should be a lot easier to deal with. And from what I understand, with LED lights you can get more yield with less plants
