I am in the US and I can only picture things in ft so excuse me for this explanation and breakdown...your tent is of a very similar dimension to mine...mine is 4 ft long and 2 feet deep and 5 ft tall...the one linked is 3 ft long 3 ft deep and 5 feet tall...so you have a foot of depth I have in length...I think depth is better, so your tent would be better than mine in the way of distribution for plant number I think, but I can squeeze in enough pot room in flower in 3-5 gallon pots to do 6, but that is really pushing it...I like to do 2 or 3 medium sized plants...but I can't transplant into final pots until right before flower, or I won't have room for clones taken and what have you in veg...so I have a lot of plants in veg, all manner of plants as well, but in flower only a couple...that way they aren't all squished up and light starved...you can put more plants in a space and get a similar yield as if you had just grown 1 or 2 plants larger, it is a preference thing...I can't seem to settle on which I like best...so I do medium plants with a small thrown in every once in awhile for fun and just to see how it turns out...I flowered a 6 in tall clone and it looks great...it is like a big cola, but instead of growing out of another plant it is growing right out of the ground. I really like it...it makes me want to do this more often...I may or may not take pics...I mean I will take some, but sharing them is a hairy issue with all the malware warnings today
