Honestly that's waay to big for a newbie & a tent.

I would take a bunch of cuts for clones, even if I had to give them away.
Guessing it might be your first time taking cuts, so do a little reading. It's not hard and if you need more straightforward answers ask here (there's a lot of what seems like conflicting info out there). Since it is probably the first time, take more cuts then what you need, and then take some more... You might get lucky and get all of them to survive but just in case... If they all survive, give some away to other patients (could always sell them I guess but giving them away builds karma).

Keep one as your new mom - read up on keeping bonzai mothers.

Veg your new clones for a couple of weeks - get them well-rooted, then flip the switch on them.
Depending on the height of your system (buckets, pots, tray, etc...) will determine how tall you'll want those clones to grow. They'll probably at least double in height after the flip so factor that in.

Good Luck!
