Yeah, I want to try and split my closet up too. Once I put mine into flower, I was gonna use the room under the grow tray to do clones. Figure id take em 1-2 weeks into flower, and im figuring 2 weeks to root, them.
This is my first grow, and I dont know the strain, so if the flowering takes anywhere from 4-5 weeks, ill be able to swap in clones after 2-3 weeks of veg, and swap the bulb back to an HPS till the next flower.
Dont always have to go horizontal ya know? If its tall, try going vertical.
Wont be or awhile till I get that set up, but ill definetly be postin pics up in my journal when I do.
Good luck man, and keep us updated. Id love to see what you workout.
I know what you mean about the grow speed though. They take off after they get some leaves, first two weeks were slow for me.
