1 tent with 2 lights vs 2 tents with 1 light

Hi guys, I have a couple of clones sitting around here that I plan on switching to flower in the next few weeks but I'm in a new living situation and am trying to figure out how to get the best yield with smallest use of space. My question is, how different will my yields be from 2 different situations. One being a 2x4 tent with a T5 48 and a 600w HPS and the other being 2 2x4 tents, one with the T5 to flower under a scrog, and the other with a 600w and a SOG.

2 tents for a perpetual setup.. you can do starters/clones/moms in one, flower in the other.. if i had the space i would get three tents.. 2 flower 1 veg/clone.. so you can clone, keep in the clone tent for however long u wanna veg, then put some in 1 tent.. take clones from your mom plant, veg again and put these in the other flower tent.. that way you harvest every so often...

if you dont understand what im trying to say here is the easiest way i can think of.. the two flower tents are tent 2 and tent 3, the veg tent is tent 1.

start seeds in tent 1, veg for lets say 3 weeks...
put the plants you vegged for 3 weeks in tent 2 for flowering..
start more seeds or use clones and veg for another 3 weeks (however long u veg)
put these in tent 3.. so you would have a tent that is 3 weeks into flowering, and a tent just starting to flower...
veg another set of plants, so when the ones in tent 2 are done, you can flower and keep the cycle going...

thats the easiest way i could put it..

That is my intention a little bit down the road, I had a little bigger set up going on before but had to relocate and have to downsize for a few months so this is just one harvest I'm talking about. I only have 2x4 space to work with but I can stack 2 2x4 tents. I have a T5 48 and a 600w HPS set up and I'm just wondering which will give me a better harvest and be more convenient if I use 2 tents both for flower or just 1 with both lights in it.

Id just use the 1 tent and switch the lights when you flower bro
