Let me see the Northern Lights

Growth is still going nicely with no issues. They are really out growing their pots, but there is method to my madness. I am actually trying to keep them as small as possible as i have another plant that is a couple of weeks behind that i wish to flower alongside. So i am just focusing on topping and keeping them level so when i put one or two of them into a 5 gal, they can have a week of veg and then flip. They are drinking a full litre a day and barely last two days at the moment. I'm thinking one more week, and i'll put one or two into a 5 gal. I was only going to keep one, but i might do two now.
