The tents are 200x200x200 ac not sure but its strong with carbon filt, i have the things. electrics are all sorted and ready, and will the 3gallons last the flower? seems to small.
There are people way more in tune with roots than me on these forums but in my personal experience i have never had problems in 3gallons. If you were to use smartpots or something similar then youll be even better. This also reflects how many plants you plan on having. With CFL's and 2 months veg you will want 3gallons since they wont be huge plants and you will want to cram as many as you can (assuming no restrictions on plant count). If you go the route of something more powerful for vegging and you have to have a lower plant count then go with the 5gallons.
For the vegging i was having it in a long cuboard so the many cfls would go along nicley, could u suggest something better similar if cfls are bad
What are the dimensions for the cupboard? Assuming it isnt some massive 4' high, 6' long and 3' wide that you could sneak a 250 or 400w in then i would look into LED's. You could pick up some cheaper Veg only (more blue) 100-200 watt sets with 3w leds.
I could tell and list you a million ways to plan your room but i dont know very much about it. So.....
I still really need to know your room size that the tents are in
Can you build your own grow room instead? IE build a divide in the middle or quarter it off.
What equipment do you already have?
How much cash can you put towards buying more stuff?
DO you prefer any training methods?
Answer all this and we can bang out a solid grow room plan to get you the best and most.
