Your welcome and I'm sure it will be a good grow either way. I just kind of chuckle at the way plant limits have changed the way we grow. The common advice now is to grow fewer plants and fill your canopy out by topping or using LTS or whatever, but back in the day we filled a canopy out by having more plants in smaller containers. In an area that size I've had as many as 49 plants using 3 liter containers. (I used to stay under the 50 plant mandatory minimum sentencing rules). Back then we often grew what was called a "sea of green". It's faster because you don't have to veg for much time, if you even have a veg cycle, instead of simply starting from 12/12. By the way, the strains you are talking about were for the most part bred to be used as part of a sea of green operation, they have fewer side branches and do great without the topping (the jack herer is the acception, it's a bit stretchy and should be topped to keep it tamed down a bit)
It's just something to keep in mind, you can fill your canopy quicker with more plants and you can grow a larger variety of strains at the same time. Variety is the spice of life. I've also never felt like I got a smaller harvest because I packed too many plants into a small space, I have gotten smaller harvests because I didn't fill my canopy though. Don't be shy about packing plants more plants into a small area, just remember that you don't have to veg for long if you do it that way.
I see this all the time when it comes to beginner mistakes, not filling out the canopy, even with old hands like me it's still tough sometimes with new strains to know how big to grow them. But sadly I see many beginners who start with just a couple plants and then waste a ton of light and a ton of time too because in that same area and in the same time they could have doubled or tippled their harvest. Since big harvests are your goal then I really do suggest starting more plants, if the limits allow it, you can veg them for less time or even start them from 12/12. Your canopy will be full and at harvest time you won't have to worry that you are only harvesting a couple of small plants. I honestly have seen more people discouraged by small harvests than anything else, they pour months of work into harvests that amount to a couple ounces of dry weed and then it never even comes close to keeping them high. The first goal of growing should be to make yourself independent of other growers, that's easy to do if you pack enough plants and light into a closet that size, in fact with that much room you should be able to grow way more than you can smoke, but only if you get into a cycle that's fast and only if you keep your canopy full, that's much easier to do with more plants.
Good luck and hit me up any time for suggestions, I love to help people out if I can.
