Whether or not you need a middle sized tent is up to you. You have to
make a plan for your propagation room, veg room, and flower room. It also
depends on how many plants you intend on keeping alive as MOMs
You can use the same space for propagation as you do veg, but I like a
separate space for all 3.
You could also use another big tent with a table to devide upper and lower
area, creating 2 chambers. Moms underneath with soft T5 lighting, and
your veg area on top, with well more T5 lighting.
Use the other tent to flower.
There you go, a couple options to chew on. Peace, lw
