Large tents. No experience. Advice welcome.

I've been lucky enough to have a chance to grow in a large bedroom of a rented apartment.
With this in mind, I thought 'great, finally some real space'.. Then i realised all my experience is with growing small 2-3 foot plants and i've no idea how to do anything else!

I've decided to purchase 2-3 large tents as the operation may need to move etc if the landlord turns out to be unsuitable etc.

I would like to get decent yeilds and use less number of plants.
My only requirements so far are soil, cooltubes in a closed loop system. No AC is apartment, but the outside temps are low enough to not need it except in the dead heat of the summer. I plan to buy a couple of dual hose portable ACs if needed. So having a sealed tent is perfectily possible.

I'm looking for some advice on plant numbers, lights, veg time, vert V horizontal.

The tents are 8 x 4 wide x 8 height.

I think 3*1000 is Max possible in this size. Would 2 be better? maybe 2 horz n one vert? how does the vert get cooled?

How tall should i grow these plants (end flowering height)?

Is using a Dual hose portable AC powerful enough to cool each tent? Along with 6inch cooltubes n Fan exhausting outside with cooling intake from outside also?

Would 10 plants be enough to fill these tents with maybe 5 weeks veg? What size pots would be needed? I've only used 7 liters.

How much would setting up a CO2 system for 2 tents cost overall? I've never used it.

Thanks for any advice. All is welcome.

I run an 8x4. 3 1000's is a little too much IMO, you'd need one hell of an AC to cool that even w/ air cooled hoods. And you'd probably end up bleaching out your plants. I do 2 600's in mine. You could probably get away with two 1000's but 3 would be pushing.

Setting up a c02 system in each tent will be roughly 800 a pop. 200 for regulator, 400 for controller, 150 ish for 20lb tank.

As for AC the rule of thumb is 5000btu per 1000w of lighting if I am not mistaken. I use a dual hose portable in mine, should work fine for you as well.

10 plants should fit perfectly in that area. I use two 3x3 flood tables in mine with a scrog to keep vertical height managed, 4-5 plants each table. Yields well.

Ah thats exactly the type of information I'm looking for. Thank you.
Would you mind if I ask roughly what you yield overall? What size pots are you using? And what are your veg times like? Thanks a bunch

In each 8x4 tent run a light rail with just one light. saves on power and reduces heat spots. I mounted my rail to a fence board and then hung it from the tent poles.
