I wanted to try a bubble bucket but my air pump is already in my cloner! My god though, that root ball is otherworldly. And hell yes to the experimenting! I've been doing the same with each one of my crops, it's all a new plant's life and since my ladies usually crop out at the same time, it's a complete restart. It's a little depressing to see that area plantless for a little while.
If you are experimenting though, I suggest getting some chicken wire and revegging one of those babies into a vine/climber after you harvest it. I've always wondered what an 8'x8' weed vine would look like.
And I think I might give my until july 1st to veg up... I want MONSTERS.
