Info needed on SCROG setup
well you can make or buy it, generally any chicken wire with 2-3 inch holes will be good for ScrOG, you put it about 5-20 inches above plants, depending on height restrictions which it doesn't sound like you'll have with 180cm of height. So for your tent, put it high enough that you have enough space to put your hands under and move around so say 10-13 inches or so above the top of the pots...
I have some brilliant stuff if you have a look at my journal I didn't buy it, I found it in the garden where I used to live but I'm sure you can pick it up from pretty much any hardware store, don't know what it's sold as or what it would be called as such, but the holes are a good 2 x 2 inches and perfect for ScrOG.
The idea is you just let the plant grow with no additional training, though I like to top my plants for 4 main colas and tie the main stems down a few times so it gives a chance for all the 'undergrowth' to catch up and reach the screen at the same time as the main stems. The principle is, you let the plant grow through the screen a few inches then pull the stems back under the screen to the next square (or hole) along you don't need to do any tying the strength of the screen should hold plant growth under.
Tip: If your using chicken wire its a good idea to tie a weight to the center of the screen or put a screw in the floor and tie the middle of the screen to it just to hold it down as chicken wire isn't very structurally sound with the force of plants pushing up on it
Tip: Try to fill out the screen anything from 50%-75% during VEG! and if in doubt flower a little earlier rather than later, as a very crowded canopy is less productive than a slightly looser one, eventually you'll get the timings bang on.
Do it right and you'll be scrogging for the rest of your life, if you like spending time with your plants, you'll be more than happy with the extra few grams - oz you'll get, I've pulled anything up to 3oZ a plant using my micro setup and some dodgy CFL's with a VERY underfilled canopy (could have fully filled the screen in hindsight and probably gotten 4-6 oz from 1 plant) now I have a hps I'm hoping to double the 3 oz mark, touch wood XD
